If you want an airplane-ready Bluetooth audio adapter with noise cancellation and a battery display, choose Avantree Relay; if you need Bluetooth earbuds with no specified noise-control feature, choose SoundPEATS PearlClip Pro &. For someone looking for the best headphones for big head, the key distinction is that Relay adds a transmitter and ANC earbuds, while the SoundPEATS listing gives much less detail about its design and features.
Avantree Relay vs SoundPEATS PearlClip Pro & at a Glance
• Avantree Relay’s biggest strength: It combines Bluetooth earbuds with an AUX audio transmitter, including a dual 3.5 mm adapter for airplane connectors. Trade-off: Its main advantage depends on having an AUX source when you want to use the transmitter.
• SoundPEATS PearlClip Pro &’s biggest strength: It is identified as wireless Bluetooth earbuds. Trade-off: The available details list no noise-control feature or additional functions to weigh against Relay.
• Avantree Relay fits: Travelers and listeners who want an airplane audio adapter, hybrid ANC, and an ambient mode in one package.
• SoundPEATS PearlClip Pro & fits: Buyers who want Bluetooth earbuds and prefer to choose based on the basic information provided, rather than on a broader feature set.
Relay is more than a pair of earbuds. It includes a Bluetooth 5.3 transmitter that takes audio from an AUX output and sends it to Bluetooth headphones or earbuds. That makes it useful with compatible sources such as airplane entertainment systems, TVs, and gym equipment. A dual 3.5 mm adapter is included for flight connectors, so the setup is designed to cover more than one common airplane jack arrangement.
It also includes Avantree Clan N1 earbuds with hybrid active noise cancellation, which the product information says can reduce environmental noise by up to 24 dB. Ambient mode uses built-in microphones to pass surrounding sound through, giving listeners an option when they need more awareness. aptX Adaptive support is another point in Relay’s favor, though the benefit depends on using a compatible listening device. The case has a display for checking battery level and charging status.

For a traveler who wants to pair wireless earbuds with a seatback entertainment system, Relay has a clear use case. It may also suit someone who wants ANC and an awareness mode without buying into a headband-style headphone design. If you only want straightforward Bluetooth earbuds for a phone and have no use for an AUX transmitter, the Relay’s adapter function may not matter much to you.
For the “big head” question, the supplied earbuds avoid a headband pressing across the top or sides of the head. That does not tell us how the earbuds will fit every person’s ears, though, and the product details don’t specify their physical dimensions or fit adjustments. I would treat Relay as a practical option for someone who dislikes headbands, not as a guaranteed fit solution.
SoundPEATS PearlClip Pro &: Who It's For
That limited feature detail matters when comparing it with Relay. Relay has a defined travel role and several listed functions; SoundPEATS is identified primarily by its wireless earbud format. I wouldn’t infer that it has a particular clip-on fit, battery life, microphone capability, or sound profile from the product name alone.
If your goal is simply to consider Bluetooth earbuds and you don’t need an airplane AUX adapter or stated noise-control features, SoundPEATS may be the more straightforward candidate to investigate. But if you need clear evidence of how a particular feature works before choosing, the information here leaves more unanswered. For a buyer searching for earphones for big head, the in-ear label suggests there is no headband, but it does not establish comfort, ear fit, or suitability for every ear shape.
• Best for airplane entertainment systems → Avantree Relay. Its transmitter accepts AUX audio, and the included dual 3.5 mm adapter is intended for airplane connectors.
• Best for connecting to an AUX source → Avantree Relay. The product specifically lists planes, TVs, and gym equipment as possible audio sources.
• Best for stated noise cancellation → Avantree Relay. Its hybrid ANC is specified as reducing environmental noise by up to 24 dB; SoundPEATS lists noise control as none.
• Best for hearing more of your surroundings while listening → Avantree Relay. Ambient mode uses microphones to transmit environmental sound.
• Best for a basic Bluetooth-earbud listing → SoundPEATS PearlClip Pro &. Its specified details cover wireless Bluetooth earbuds and in-ear placement, without a stated transmitter or noise-control mode.
• Best for codec details → Avantree Relay. aptX Adaptive is listed, with the qualification that the listening device must support it to benefit.
• Best for checking case battery status → Avantree Relay. Its case includes a battery and charging-status display.
• Best for someone avoiding a headband → Neither has a listed headband. Both are described as earbuds, but the available details do not establish which will fit more comfortably for a particular head or ear shape.
My Verdict
I would choose Avantree Relay for a big-head listening setup, especially if I wanted earbuds for flights and a way to use airplane AUX audio. Its transmitter, hybrid ANC, ambient mode, and battery display make its purpose much clearer. SoundPEATS PearlClip Pro & remains a reasonable option to consider for basic Bluetooth earbuds, but the listed details give me less to go on when comparing features.
FAQ
Avantree Relay is the clearer choice for airplane entertainment systems because its transmitter takes AUX audio and includes a dual 3.5 mm adapter for flight connectors. The SoundPEATS details identify Bluetooth earbuds but do not list an AUX transmitter.
Avantree Relay includes hybrid ANC, with noise reduction specified up to 24 dB, plus an ambient mode that passes environmental sound through its microphones. SoundPEATS PearlClip Pro & lists no noise-control feature.
Neither product is described as using a headband, so either may be worth considering if headband pressure is your concern. The information provided doesn’t establish how each will fit your ears, so it can’t determine comfort for a specific person.
Value depends on the features you need and the current price, which you should check on Amazon. Based on the listed features alone, Relay offers more specified functions; SoundPEATS is identified as Bluetooth earbuds without those extras.
