How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one purchase that covers hi-res listening on the ground and serious noise cancelling on the move, choose SoundPEATS Air6; if you need to turn a plane's seat-back screen into a two-person wireless listening session, choose Avantree Relay & SoundJet. Those are two different jobs, and the spec sheets make the split unusually clean. The Air6 bundle is a pair of listening devices — earbuds plus over-ear-style headphones. The Avantree kit is a transmitter, not a listening device at all, and it exists for one scenario: flights.
• SoundPEATS Air6 — biggest strength: two hi-res audio devices in one bundle, with LDAC support, Bluetooth 6.0 on the earbuds, and up to 55dB adaptive hybrid ANC on the H3 headphones.
• SoundPEATS Air6 — biggest trade-off: it's a bundle of two products, so the feature set is split between them — the 55dB ANC, the 37-hour figure and the six mics belong to the H3, not the Air6 HS earbuds.
• Avantree Relay & SoundJet — biggest strength: it pairs two Bluetooth headphones to one in-flight audio source at the same time, with Qualcomm aptX Adaptive and up to 25 hours of playtime.
• Avantree Relay & SoundJet — biggest trade-off: it is a Bluetooth transmitter only. It does not pair with phones or tablets and is not for TVs, hearing aids or musical instruments.
• Who each pick is for: the Air6 bundle suits someone who wants better everyday audio across earbuds and headphones; the Avantree Relay suits frequent flyers and couples who want to share a seat-back screen.
The Air6 HS earbuds are built around a 13mm triple-magnet driver — one main magnet plus two auxiliary ones in a Neodymium circuit. The engineering claim behind that design is a higher magnetic flux, which the sheet links to more driving force, lower distortion and a faster transient response. In plain terms: this is a driver configuration aimed at punch and clarity rather than a generic single-magnet setup. Add Bluetooth 6.0 on a 22nm chipset, and the pitch is power efficiency plus a stable connection with multi-device switching and stronger anti-interference. LDAC support is the part that matters most for the "aptX HD" question — more on that below.
Who should buy it: anyone who wants a single purchase covering both in-ear and over-ear listening, values LDAC hi-res playback, and wants a genuinely deep noise-cancelling mode for commuting or travel. Who should skip it: someone who only needs one pair of earbuds, or whose priority is a specific aptX codec rather than LDAC.
Avantree Relay & SoundJet: Who It's For
The Avantree Relay & SoundJet R1 is not earbuds and not headphones. It's a Bluetooth transmitter designed for airplane use, and the sheet is refreshingly blunt about its limits: not compatible with TVs, hearing aids or musical instruments, and it does not pair with phones or tablets. If you were hoping to use it as a general-purpose audio adapter at home, this is not that product.
What it does, it does specifically. It lets you pair two Bluetooth headphones or AirPods to the same source at once, so two people can watch the same in-flight entertainment side by side. Audio runs on Qualcomm aptX Adaptive, which the sheet frames as balanced sound and dependable wireless performance. Playtime is up to 25 hours on a single charge — a figure aimed squarely at long international flights rather than short hops.
Who should buy it: frequent flyers, couples and travel partners who want to share a seat-back screen wirelessly, especially if they already own good Bluetooth headphones. Who should skip it: anyone looking for earbuds, anyone who wants noise cancelling, and anyone who needs an adapter for a TV at home. It's a single-purpose travel tool, and it should be bought as one.
Side-by-Side: Which Should You Choose?
• Best for hi-res everyday listening → SoundPEATS Air6. LDAC support on both the Air6 HS and the H3, plus a 13mm triple-magnet driver in the earbuds.
• Best for battery on a single device → SoundPEATS Air6. 7 hours per charge and 37 hours total with the case on the H3, plus 10-minute quick charging for 2 hours.
• Best for sharing audio with a travel partner → Avantree Relay & SoundJet. Two headphones or AirPods paired to one source simultaneously.
• Best for long-haul flights → Avantree Relay & SoundJet. Up to 25 hours of playtime, sized for international travel.
• Best for frequent recharging → SoundPEATS Air6. Quick charging is an explicit feature; the Avantree sheet lists playtime but no fast-charge figure.
• Best for app-based personalisation → SoundPEATS Air6. The PeatsAudio app covers EQ, custom touch controls, multi-point, battery display and fit test.
• Best for a single, narrow purpose → Avantree Relay & SoundJet. It's a transmitter only, and it knows it.
In my opinion, the SoundPEATS Air6 bundle is the better buy for most people, simply because it covers far more ground: two devices, LDAC, deep ANC on the H3, quick charging and app control. If you fly often — or you travel with someone and want to share the screen — the Avantree Relay & SoundJet earns its place as a dedicated travel accessory, and I'd recommend it for exactly that. But as a standalone purchase, it only solves one problem. Check the current price on Amazon for both before deciding, since the value math shifts depending on what you already own.
which earbuds support aptx hd
Neither product here lists aptX HD by name. The SoundPEATS Air6 bundle specifies LDAC as its hi-res codec, while the Avantree Relay & SoundJet uses Qualcomm aptX Adaptive. If aptX HD specifically is your requirement, these two are not the match — but if you want hi-res wireless audio, LDAC on the Air6 is the relevant credential.
They're different codec families from different developers. LDAC, listed on the SoundPEATS Air6 bundle, is Sony's hi-res codec. aptX Adaptive, listed on the Avantree Relay & SoundJet, comes from Qualcomm and is described in the sheet as delivering balanced sound with dependable wireless performance. Both aim at better-than-basic Bluetooth audio; the sheet doesn't rank one above the other.
Yes — the H3 headphones in the bundle are the travel-oriented half, with adaptive hybrid ANC rated up to 55dB and a transport mode among the four app-selectable settings. Battery runs 7 hours per charge and 37 hours total with the case, and 10 minutes of charging returns 2 hours of playtime. Note that the Air6 bundle does not include a Bluetooth transmitter for seat-back screens.
Yes. The sheet states it pairs two Bluetooth headphones or AirPods to the same source simultaneously, which is its headline feature for couples and travel partners. Playtime is up to 25 hours per charge. Just remember it won't work with TVs, phones, tablets, hearing aids or musical instruments.
