If you want immersive, noise-cancelling earbuds for Switch, choose Yamaha TW-E7B; if you need a Bluetooth transmitter to share audio from an AUX source, choose Avantree Relay. The key distinction is simple: Yamaha is the listening device, while Relay sends sound from a wired audio output to Bluetooth headphones. For Switch use, choose based on whether you want earbuds or need an AUX transmitter in your setup.
• Yamaha TW-E7B: In-ear Bluetooth earbuds with active noise cancellation, Yamaha True Sound and IPX5 water resistance; the trade-off is up to six hours of battery life.
• Avantree Relay: A Bluetooth 5.3 AUX transmitter that can connect to two headphones or earbuds; the trade-off is that it is not a pair of headphones and requires an AUX audio source.
• For Switch: Yamaha is the more direct choice if you want Bluetooth earbuds for personal listening; Relay is relevant only if your setup provides audio through a 3.5 mm AUX output.
• Choose Yamaha for a self-contained listening option with noise control, call-focused microphone features and water resistance.
• Choose Relay for sending AUX audio to Bluetooth headphones, sharing with a second listener or connecting to a compatible travel or TV output.
The Yamaha TW-E7B is a pair of true wireless, in-ear earbuds with Bluetooth 5.2. Its listed audio features include active noise cancellation, Yamaha True Sound and Advanced Listening Care, which adjusts loudness to retain a fuller range at lower listening volumes. That combination makes it the more straightforward pick if your priority is wearing earbuds and listening to Switch audio without a separate transmitter.
There are practical extras beyond music playback. Yamaha lists Qualcomm cVc Clear Voice Capture for calls and an IPX5 water-resistance rating for sweat and weather. The included eartips come in five sizes, from XS through XL, so you can choose among the supplied options. That makes the TW-E7B a better fit for someone who wants one set of earbuds for gaming, calls and active use—not just a device for an airplane seat.
The main trade-off is battery life: Yamaha lists an average of six hours. That may be enough for a gaming session or commute, but it is a shorter figure than Relay’s stated maximum runtime. Skip the TW-E7B if your actual need is to transmit sound from an AUX port to two listeners; these are earbuds, not an audio adapter.

Relay’s standout flexibility is its ability to connect up to two listening devices, so two people can share audio. It supports aptX Adaptive and aptX Low Latency when paired with compatible listening devices. That makes it worth considering if you are looking for low-latency audio from an AUX source, though the codec support alone does not establish that it will work with every Switch setup or produce a particular latency in every pairing.
The device offers up to 20 hours of battery life, built-in controls for functions such as volume and pairing, and LED indicators for connections and battery levels. It can also continue operating while charging. But it cannot replace earbuds: you need a separate pair of Bluetooth headphones or earbuds, and you need an AUX audio output. If you want a direct, wearable Switch listening option, Relay is not the same kind of product as Yamaha.
• Best fit for personal Switch listening with earbuds → Yamaha TW-E7B. It is the actual listening device, with in-ear placement and Bluetooth 5.2. Relay needs a compatible AUX source and separate Bluetooth headphones.
• Best for sharing AUX audio with another listener → Avantree Relay. It can connect to up to two headphones or earbuds; the Yamaha earbuds are a personal listening choice.
• Best for noise control → Yamaha TW-E7B. Active noise cancellation is listed as a feature. Relay transmits audio and does not provide noise cancellation itself.
• Best for water and sweat resistance → Yamaha TW-E7B. It has an IPX5 rating, which suits buyers who want an option for sport or weather.
• Best for long stated battery life → Avantree Relay. It is listed for up to 20 hours, compared with Yamaha’s six-hour average. These figures describe different kinds of devices, so think about whether you need transmitter runtime or earbud listening time.
• Best for calls → Yamaha TW-E7B. Its advanced microphone design and Qualcomm cVc Clear Voice Capture are intended to support clearer calls. Relay’s listed role is audio transmission.
• Best for AUX-based travel setups → Avantree Relay. It connects to AUX outputs, includes a dual 3.5 mm adapter and can send audio to two listening devices.
• Best low latency earphones for Switch → Yamaha is the more relevant product category, but neither sheet establishes a guaranteed Switch latency. Relay supports aptX Low Latency with compatible headphones, yet it is a transmitter rather than earphones, and the connection depends on the source and listening devices.
My Verdict
I’d choose the Yamaha TW-E7B for Switch if I wanted a pair of earbuds for personal listening, especially because it combines active noise cancellation with IPX5 water resistance and call-focused microphone features. Its six-hour average battery life is the main compromise to weigh.
No. Yamaha TW-E7B is a pair of in-ear Bluetooth earbuds. Avantree Relay is a Bluetooth transmitter that sends audio from an AUX output to separate Bluetooth headphones or earbuds.
Relay is described for devices that output audio through AUX. The product information does not specifically confirm a Switch connection, so check that your intended setup provides a compatible 3.5 mm audio output before choosing it.
Relay supports aptX Low Latency when used with compatible listening devices, but that does not guarantee low latency with every source or pair of headphones. The Yamaha sheet does not specify a latency figure. For Switch gaming, confirm that the complete source-and-headphone setup supports the connection you need.
Avantree Relay is listed for up to 20 hours and can be used while charging. Yamaha TW-E7B is listed with an average battery life of six hours. These are different device types, so consider whether you need longer transmitter runtime or earbuds for direct listening.
