=== Setting up a truly wireless surround sound system involves two challenges: wireless audio transmission (to eliminate speaker cables) and wireless power (to eliminate power cords). Below, we outline solutions for both aspects, prioritizing sound quality. We focus on a 5.1 setup (five speakers + subwoofer) with options to expand to 7.1, and analyze whether emerging wireless power technologies (like Etherdyne’s) can power such a system. ===

==== Modern TVs like the Sony 65A95K support HDMI eARC (Enhanced Audio Return Channel), which can pass high-bitrate surround sound from the TV to an external audio system. To maintain top audio quality without wires, you’ll want a wireless audio transmitter that plugs into the TV’s eARC port and sends multi-channel audio to powered speakers: ====
* WiSA SoundSend Transmitter: A compact HDMI-ARC/eARC wireless transmitter that decodes the TV’s audio (up to Dolby Atmos) and broadcasts up to 8 channels of uncompressed 24-bit/48–96 kHz sound to compatible speakersplatinaudio.com<ref>{{cite web|title=platinaudio.com|url=https://www.platinaudio.com/products/wisa-soundsend-wireless-audio-transmitter#:~:text=As%20a%20small%20wireless%20home,room%20into%20a%20home%20theater|publisher=platinaudio.com|access-date=2025-11-29}}</ref>platinaudio.com<ref>{{cite web|title=platinaudio.com|url=https://www.platinaudio.com/products/wisa-soundsend-wireless-audio-transmitter#:~:text=Key%20Features|publisher=platinaudio.com|access-date=2025-11-29}}</ref>.

* Enclave CineHub (WiSA) Transmitter: Enclave Audio’s systems include a small HDMI hub that similarly connects to the TV’s ARC port and transmits high-quality wireless audio. (This is essentially a dedicated WiSA transmitter branded for their speaker kits.) For example, the Enclave CineHub uses the WiSA standard to send up to 8 channels of 24-bit/96 kHz audio with <5.2 ms latency, and on interference-free frequenciespopsci.com<ref>{{cite web|title=popsci.com|url=https://www.popsci.com/reviews/enclave-cinehome-wireless-home-theater/#:~:text=The%20CineHub%20wireless%20unit%20ties,Fi%20and%20Bluetooth|publisher=popsci.com|access-date=2025-11-29}}</ref>. It’s ARC-compatible (with eARC firmware updates adding support for lossless formats)popsci.com<ref>{{cite web|title=popsci.com|url=https://www.popsci.com/reviews/enclave-cinehome-wireless-home-theater/#:~:text=Raiders%20of%20the%20Lost%20ARC|publisher=popsci.com|access-date=2025-11-29}}</ref>.

Both options achieve the goal of wirelessly delivering surround sound from the TV to the speakers. WiSA (Wireless Speaker & Audio Association) is the key technology here – it’s a standard for high-res, low-latency wireless home theater audio. Many modern wireless surround systems use WiSA under the hood (including the Platin and Enclave systems discussed below). With WiSA, you avoid the lag and sync issues that plague Bluetooth solutions – WiSA is designed specifically for home theater, maintaining microsecond-level sync between speakerspopsci.com<ref>{{cite web|title=popsci.com|url=https://www.popsci.com/reviews/enclave-cinehome-wireless-home-theater/#:~:text=The%20CineHub%20wireless%20unit%20ties,Fi%20and%20Bluetooth|publisher=popsci.com|access-date=2025-11-29}}</ref>.

7.1 Channels: If you want to expand to 7.1, WiSA can support it by adding two additional surround speakers (WiSA handles up to 8 discrete channels). For instance, the SoundSend transmitter can transmit to up to 11 speakers (e.g. a 7.1 or 5.1.2 Atmos setup) as long as they are WiSA-enabledplatinaudio.com<ref>{{cite web|title=platinaudio.com|url=https://www.platinaudio.com/products/wisa-soundsend-wireless-audio-transmitter#:~:text=included%29%20,DTS%20formats%20are%20not%20supported|publisher=platinaudio.com|access-date=2025-11-29}}</ref>platinaudio.com<ref>{{cite web|title=platinaudio.com|url=https://www.platinaudio.com/products/wisa-soundsend-wireless-audio-transmitter#:~:text=any%20position%2C%20with%20a%20maximum,WiSA%20wireless%20formats|publisher=platinaudio.com|access-date=2025-11-29}}</ref>. This means you could start with a 5.1 set and later add two wireless rear-back speakers to achieve 7.1, configuring the system via the WiSA transmitter’s app.

==== Since sound quality is the top priority and no brand is off-limits, we recommend the following wireless surround speaker systems that pair with the above transmitters. These systems deliver true surround sound with no audio cables to the speakers (only power cords are needed for each unit): ====
* Enclave CineHome Pro 5.1 (THX Certified): This is a high-end 5.1 speaker package that delivers excellent sound. It consists of separate front left/right towers, a center speaker, two surrounds, and a 10-inch subwoofer (all speakers are active/powered). The CineHome Pro uses the WiSA wireless audio standard (24-bit, 96 kHz) for lossless surround transmission with THX certification for audio qualitypopsci.com<ref>{{cite web|title=popsci.com|url=https://www.popsci.com/reviews/enclave-cinehome-wireless-home-theater/#:~:text=however%2C%20because%20while%20Bluetooth%20surround,HDMI%20cable%20from%20your%20TV|publisher=popsci.com|access-date=2025-11-29}}</ref>. A central Enclave CineHub transmitter (included) connects to your TV’s HDMI ARC/eARC and sends audio to all speakers with only a 5 ms latency. In reviews, this system is praised for “wireless surround done right,” delivering immersive, high-fidelity sound without any speaker wires running across the roompopsci.com<ref>{{cite web|title=popsci.com|url=https://www.popsci.com/reviews/enclave-cinehome-wireless-home-theater/#:~:text=actual%20theater%20experience%3A%20the%20sound,system%20offers%20considerable%20audio%20quality|publisher=popsci.com|access-date=2025-11-29}}</ref>popsci.com<ref>{{cite web|title=popsci.com|url=https://www.popsci.com/reviews/enclave-cinehome-wireless-home-theater/#:~:text=The%20CineHub%20wireless%20unit%20ties,Fi%20and%20Bluetooth|publisher=popsci.com|access-date=2025-11-29}}</ref>. (Do note that each speaker and the subwoofer still plug into a wall outlet for power.) The Enclave Pro’s sound quality is superb – it has 11 Class-D amps built-in (one per driver) and can get loud and detailed enough for a true home theater experiencepopsci.com<ref>{{cite web|title=popsci.com|url=https://www.popsci.com/reviews/enclave-cinehome-wireless-home-theater/#:~:text=Altogether%2C%20the%20CineHome%20PRO%20system,any%20time%20if%20they%20wish|publisher=popsci.com|access-date=2025-11-29}}</ref>. It supports standard Dolby Digital/DTS formats; a promised firmware update is adding eARC support for HD audio. If desired, Enclave allows adding a second subwoofer for 5.2, though expanding to 7.1 might require using a WiSA transmitter like SoundSend with additional WiSA speakers (Enclave currently focuses on 5.1). popsci.com<ref>{{cite web|title=popsci.com|url=https://www.popsci.com/reviews/enclave-cinehome-wireless-home-theater/#:~:text=Altogether%2C%20the%20CineHome%20PRO%20system,any%20time%20if%20they%20wish|publisher=popsci.com|access-date=2025-11-29}}</ref> Enclave CineHome PRO 5.1 – a WiSA-based wireless surround system. All speakers receive audio wirelessly from the central HDMI CineHub (small box in front), requiring only power cables for each speaker.
* Platin Monaco 5.1 (WiSA Bundle): The Platin Monaco is another WiSA-certified 5.1 system, often sold bundled with the WiSA SoundSend transmitter. It includes compact high-performance speakers (4 satellites + 1 center + 1 sub). You simply connect the SoundSend to the TV’s eARC port, place the Platin speakers around your room, and plug each into power. The SoundSend will transmit lossless 5.1 audio to them with 24-bit clarityplatinaudio.com<ref>{{cite web|title=platinaudio.com|url=https://www.platinaudio.com/products/wisa-soundsend-wireless-audio-transmitter#:~:text=As%20a%20small%20wireless%20home,room%20into%20a%20home%20theater|publisher=platinaudio.com|access-date=2025-11-29}}</ref>. This system is known for easy setup and very clean, accurate sound for its size (it even earned a THX Select certification for room-filling sound). It supports Dolby Digital Plus and even Dolby TrueHD/Atmos (up to 5.1.2 channels) when using eARCplatinaudio.com<ref>{{cite web|title=platinaudio.com|url=https://www.platinaudio.com/products/wisa-soundsend-wireless-audio-transmitter#:~:text=The%20wireless%20home%20cinema%20Audio,2%20Dolby%20Atmos|publisher=platinaudio.com|access-date=2025-11-29}}</ref>. The satellites are small enough to be unobtrusive, but deliver a balanced soundstage. Like the Enclave, no speaker wires are needed – only AC power to each unit.
* Other WiSA-Compatible Speakers: One benefit of WiSA is that you can mix-and-match any certified speakers and subs. High-end audiophile brands offer WiSA options – for example, Bang & Olufsen, Buchardt Audio, Harman/Kardon, System Audio, and Klipsch have WiSA-enabled speakersplatinaudio.com<ref>{{cite web|title=platinaudio.com|url=https://www.platinaudio.com/products/wisa-soundsend-wireless-audio-transmitter#:~:text=SoundSend%20meets%20the%20highest%20globally,Buchardt%2C%20System%20Audio%2C%20B%26O%2C%20etc|publisher=platinaudio.com|access-date=2025-11-29}}</ref>. If budget is no issue and quality is paramount, you could assemble a premium 5.1 system using such speakers. For instance, Buchardt makes the WiSA-enabled A500 active speakers which could serve as superb front channels, or Klipsch Reference Wireless speakers could be used for mains and surrounds. These would all work seamlessly with a WiSA transmitter like the SoundSendplatinaudio.com<ref>{{cite web|title=platinaudio.com|url=https://www.platinaudio.com/products/wisa-soundsend-wireless-audio-transmitter#:~:text=SoundSend%20meets%20the%20highest%20globally,Buchardt%2C%20System%20Audio%2C%20B%26O%2C%20etc|publisher=platinaudio.com|access-date=2025-11-29}}</ref>platinaudio.com<ref>{{cite web|title=platinaudio.com|url=https://www.platinaudio.com/products/wisa-soundsend-wireless-audio-transmitter#:~:text=,WiSA%20wireless%20formats|publisher=platinaudio.com|access-date=2025-11-29}}</ref>. Keep in mind each speaker still needs a power source. (Some of these higher-end speakers come with external power bricks supplying DC power, which might be helpful for integrating wireless power as discussed later.)

7.1 Upgrade: If you start with a 5.1 WiSA system (like Platin or Enclave), you can later add two extra wireless surround speakers to create a 7.1 configuration, provided the transmitter supports it. The WiSA SoundSend, for example, supports up to 8 channels (7.1) – you would designate the additional speakers as “rear surrounds” in the WiSA controller app. This gives you flexibility to expand your setup for even more immersive sound.

Soundbars vs. Discrete Speakers: Note that while some soundbar systems offer wireless rear speakers and subs, they often use compressed transmission or lower power drivers. Discrete speakers will generally yield better sound quality and channel separationpopsci.com<ref>{{cite web|title=popsci.com|url=https://www.popsci.com/reviews/enclave-cinehome-wireless-home-theater/#:~:text=actual%20theater%20experience%3A%20the%20sound,system%20offers%20considerable%20audio%20quality|publisher=popsci.com|access-date=2025-11-29}}</ref>. Since quality is your priority, the WiSA-based separates (like Enclave or Platin) are recommended over an all-in-one soundbar kit. For example, the JBL Bar 9.1 does have truly wireless battery-powered rear modules, but those are a compromise in fidelity and are meant to dock into the soundbar for charging. A dedicated WiSA system with full-range speakers will outperform such solutions in audio quality and dynamics.

==== Eliminating the power cords for each speaker is far more challenging, as high-quality speakers and subwoofers require significant power. Currently, mainstream wireless surround systems still require each speaker to be plugged into an outlet for powerpopsci.com<ref>{{cite web|title=popsci.com|url=https://www.popsci.com/reviews/enclave-cinehome-wireless-home-theater/#:~:text=Altogether%2C%20the%20CineHome%20PRO%20system,any%20time%20if%20they%20wish|publisher=popsci.com|access-date=2025-11-29}}</ref>. However, you mentioned Etherdyne’s wire-free power technology – an emerging solution that can beam power through the air over a short range. Let’s examine this and similar technologies for wireless electricity, and see if they could drive a 5.1 speaker setup: ====
* Etherdyne Technologies (ETI) Wire-Free Power: Etherdyne’s evaluation kit demonstrates a magnetic resonance power system capable of delivering usable power within a 3D zone (for example, a desktop area). It consists of a 100 W RF power transmitter and a large loop antenna that you can embed in a surface (like under a desk or into a ceiling panel)etherdyne.net<ref>{{cite web|title=etherdyne.net|url=https://www.etherdyne.net/evalkit#:~:text=%2A%20|publisher=etherdyne.net|access-date=2025-11-29}}</ref>. On the device side, you attach small receiver coils that convert the magnetic field to DC power. The kit includes receivers of various sizes; notably, the largest (130 mm diameter) receiver outputs 24 V DC at up to ~7 W of power, with smaller coils providing proportionally less poweretherdyne.net<ref>{{cite web|title=etherdyne.net|url=https://www.etherdyne.net/evalkit#:~:text=Rx2%2046mm%2C%205V%20Output%20Voltage%2C,Output%20Voltage%2C%207W%20Output%20Power|publisher=etherdyne.net|access-date=2025-11-29}}</ref>. The system can power multiple devices simultaneously (up to a combined 100 W across the zone) – e.g. in a demo, one creator powered a monitor, LED lamp, a microphone, and a pair of small stereo speakers all at once, showing “the power these things can pull”hackaday.com<ref>{{cite web|title=hackaday.com|url=https://hackaday.com/2025/06/08/wireless-power-makes-for-cable-free-desk/#:~:text=The%20kit%20from%20ETI%20contained,power%20these%20things%20can%20pull|publisher=hackaday.com|date=2025-06-08|access-date=2025-11-29}}</ref>.

In the Etherdyne evaluation kit, multiple sizes of these receiver coils are provided, outputting DC power (5–24 V) at a few watts each. To use Etherdyne for your speakers, you would embed a receiver coil into each speaker and the subwoofer, connecting it to the speaker’s internal power input. Many active speakers run on DC internally (often 12 V or 24 V), so in theory a 24 V wireless receiver could feed the amplifier directly. Compatibility in terms of voltage is promising – e.g. Etherdyne’s larger receivers output 24 V which matches common amp supply rails. However, power output is the limiting factor: ~7 W per receiver is much lower than what a decent speaker or subwoofer typically draws. For context, a small bookshelf speaker might use on the order of 20–50 W when playing loud, and a subwoofer can easily demand 100 W+ for deep bass. With only 7 W available, a speaker would either be very quiet or starved of headroom. Even if each speaker had one coil, the total 5.1 system could only get ~35 W plus ~7 W for the sub (42 W total), which is likely insufficient for dynamic home theater sound. The 100 W transmitter capacity isn’t the bottleneck – the issue is each receiver’s limited wattage. There are a few workarounds one might consider: using multiple receiver coils per speaker to increase power (for example, two coils could double the available wattage). In practice, this would be a complex DIY modification – you’d need to physically attach multiple coils in or on the speaker, each wired either to separate power circuits or combined to feed the amplifier. The transmitter’s 100 W budget could support this in aggregate (e.g. 4–5 coils drawing ~20 W each), but it’s unclear if the system can efficiently drive many large receivers concurrently. Etherdyne’s tech is still in an R&D phase (the product is an evaluation kit intended for prototyping), so scaling it up would require experimentation. Also, to cover an entire living room, you might need a larger or differently placed transmitter loop. The standard loop is optimized for a desk-sized areaprnewswire.com<ref>{{cite web|title=prnewswire.com|url=https://www.prnewswire.com/news-releases/powercast-adds-etherdynes-magnetic-resonance-to-its-wireless-power-portfolio-302495266.html#:~:text=Powercast%27s%20Magnetic%20Resonance%20technology%2C%20powered,Free|publisher=prnewswire.com|access-date=2025-11-29}}</ref>. For a living room, you might need to embed the loop in the floor or ceiling to encompass the seating area and all speaker positions. This is technically possible but would involve a custom installation (e.g. running the loop wire under your floorboards or in the attic above the room). Signal strength diminishes with distance, so each speaker likely needs to be within a meter or so of the loop plane for reliable power.
* Other Wireless Power Technologies: Etherdyne (now partnered with Powercast) is at the forefront of mid-range wireless power. Alternatives include WiTricity (magnetic resonance, known for wireless EV charging and some consumer electronics) and Energous WattUp or Powercast RF (far-field RF power). WiTricity focuses on higher-power transfer (tens to hundreds of watts) but usually at short range (inches to a few inches, or targeted solutions like car charging pads). It’s not commercially available as a living-room-spanning system yet – mostly in prototype stages for TVs/monitors or automotive use. Energous/Powercast (RF) can send power over longer distances, but only in the milliwatt-to-watt range suitable for small gadgets and sensorsprnewswire.com<ref>{{cite web|title=prnewswire.com|url=https://www.prnewswire.com/news-releases/powercast-adds-etherdynes-magnetic-resonance-to-its-wireless-power-portfolio-302495266.html#:~:text=%2A%20Over,toothbrushes%20and%20shavers%2C%20and%20more|publisher=prnewswire.com|access-date=2025-11-29}}</ref> – not nearly enough for speakers. In fact, Powercast has integrated Etherdyne’s resonant tech to fill this mid-power, mid-range gap (i.e. powering multiple devices in a room with up to ~100 W total)prnewswire.com<ref>{{cite web|title=prnewswire.com|url=https://www.prnewswire.com/news-releases/powercast-adds-etherdynes-magnetic-resonance-to-its-wireless-power-portfolio-302495266.html#:~:text=Powercast%27s%20Magnetic%20Resonance%20technology%2C%20powered,Free|publisher=prnewswire.com|access-date=2025-11-29}}</ref>. So at this time, Etherdyne’s solution is the most viable for attempting a truly wire-free audio setup.

Bottom Line – Is True Wireless Power Feasible for Now? In its current form, **wireless power tech can run low-power audio devices (like small desktop speakers or voice assistants), but for hi-fi speakers and subwoofers it’s on the bleeding edge. You could certainly experiment with the Etherdyne kit in a DIY project – for example, embed a transmitter coil in your living room ceiling and install 2–3 receiver coils into each speaker’s circuitry. This might power small satellite speakers at modest volume. In fact, the DIY Perks project demonstrated powering stereo speakers on a desk along with other peripherals using Etherdyne’s kithackaday.com<ref>{{cite web|title=hackaday.com|url=https://hackaday.com/2025/06/08/wireless-power-makes-for-cable-free-desk/#:~:text=The%20kit%20from%20ETI%20contained,power%20these%20things%20can%20pull|publisher=hackaday.com|date=2025-06-08|access-date=2025-11-29}}</ref>. However, to faithfully drive a full 5.1 home theater at reference volume, the technology isn’t quite ready to replace all power cables. You’d risk clipping or reduced sound quality if the amps can’t draw enough power for demanding scenes.

==== Given the analysis, here’s what we suggest: ====
# Use a WiSA-based Wireless Audio System for 5.1 (Expandable to 7.1): This ensures top-tier sound quality and hassle-free surround sound with no speaker wires. For example, the Enclave CineHome Pro 5.1 or a WiSA SoundSend + Platin Monaco 5.1 will leverage your TV’s eARC output and deliver true surround with minimal latencyplatinaudio.com<ref>{{cite web|title=platinaudio.com|url=https://www.platinaudio.com/products/wisa-soundsend-wireless-audio-transmitter#:~:text=Key%20Features|publisher=platinaudio.com|access-date=2025-11-29}}</ref>popsci.com<ref>{{cite web|title=popsci.com|url=https://www.popsci.com/reviews/enclave-cinehome-wireless-home-theater/#:~:text=The%20CineHub%20wireless%20unit%20ties,Fi%20and%20Bluetooth|publisher=popsci.com|access-date=2025-11-29}}</ref>. These systems have proven performance (THX-certified in the case of Enclave) and will fully utilize high-bitrate audio from Blu-rays, games, and streaming. You’ll get the immersive experience you’re looking for, and you can upgrade to 7.1 later by adding speakers if needed.
# For Now, Plan on Wired Power (AC outlets) for Each Speaker: In the interest of sound quality and reliability, it’s prudent to use normal power cables (at least until wireless power tech matures a bit more). Each speaker in the recommended systems comes with its own power adapter or cord – you can hide these along baseboards or use outlets behind furniture. This ensures each speaker’s built-in amplifier can draw ample power (often tens of watts) for dynamic audio. It’s a small concession – as one reviewer noted, you avoid running long speaker wires, but you will need several wall outlets for the wireless speakerspopsci.com<ref>{{cite web|title=popsci.com|url=https://www.popsci.com/reviews/enclave-cinehome-wireless-home-theater/#:~:text=Altogether%2C%20the%20CineHome%20PRO%20system,any%20time%20if%20they%20wish|publisher=popsci.com|access-date=2025-11-29}}</ref>.
# Keep an Eye on Wireless Power Developments: If you’re keen on true wireless power, you can start experimenting with kits like Etherdyne’s. They are compatible in principle – for instance, Etherdyne receivers output 24 V DCetherdyne.net<ref>{{cite web|title=etherdyne.net|url=https://www.etherdyne.net/evalkit#:~:text=Rx4%2068mm%2C%2012V%20Output%20Voltage%2C,Output%20Voltage%2C%207W%20Output%20Power|publisher=etherdyne.net|access-date=2025-11-29}}</ref>, which matches many speakers’ requirements. You would likely bypass or supplement the speaker’s AC power supply with the wireless receiver. Just be mindful of the power limitations (7 W per receiver in the current eval kitetherdyne.net<ref>{{cite web|title=etherdyne.net|url=https://www.etherdyne.net/evalkit#:~:text=Rx2%2046mm%2C%205V%20Output%20Voltage%2C,Output%20Voltage%2C%207W%20Output%20Power|publisher=etherdyne.net|access-date=2025-11-29}}</ref>). It might be feasible to use wireless power for low-draw components (say, the rear surround speakers at low volume, or LED indicators, etc.) and still plug in the power-hungry subwoofer, as a hybrid approach. In any case, as technology improves, we expect higher-power wireless transfer (e.g. future Etherdyne/Powercast systems or WiTricity solutions) to become available – perhaps making truly cable-free home theaters viable in a few years. For now, to achieve top audio quality, a partly wired solution is the safe bet.

In summary, you can absolutely create a high-fidelity wireless surround setup for your Sony TV today: use an eARC-connected WiSA transmitter with quality wireless speakers for the audio, and accept that those speakers will each need a power source (whether a cord or an ambitious DIY wireless-power mod).
