If you want a travel-ready Bluetooth transmitter that turns any wired audio source into a wireless listening station, choose Avantree Relay; if you need open-ear earbuds with hybrid ANC, long playback and built-in AI translation, choose TAGRY Hybrid Active Noise.
• Avantree Relay — biggest strength: It is a Bluetooth 5.3 transmitter with aptX-Adaptive codec support, so it takes audio from any AUX-output device (plane seatback screens, TVs, gym equipment) and sends it wirelessly to essentially any Bluetooth headphones or earbuds. The bundled dual 3.5mm adapter means it works on any flight connector type.
• Avantree Relay — biggest trade-off: It is not a standalone listening product. You need your own Bluetooth headphones or earbuds to hear anything through it, and its ANC (up to 24dB) lives on the paired Clan N1 earbuds side of the bundle, not the transmitter itself.
• TAGRY Hybrid Active Noise — biggest strength: A complete all-in-one package: open-ear C-shaped clip design, hybrid ANC that claims to block over 95% of ambient noise, Hi-Res audio with 13mm drivers, Bluetooth 5.4, up to 56 hours total playback with the charging case, plus real-time AI translation across 164 languages with no subscription.
• TAGRY Hybrid Active Noise — biggest trade-off: Open-ear designs trade some passive isolation and deep bass seal for situational awareness, and the translation and 8-in-1 assistant features are only useful if you actually need them — otherwise you are paying for complexity.
• Who the Avantree Relay is for: Frequent flyers, hotel-room TV watchers and gym users who already own good Bluetooth headphones and want to cut the cord on wired audio sources.
• Who the TAGRY Hybrid Active Noise is for: Runners, commuters, travelers and multilingual users who want one pair of earbuds to handle music, calls, awareness and translation without juggling accessories.
The Avantree Relay is best understood as a bridge, not a pair of earbuds in the usual sense. Its core job is to take a wired audio signal — the 3.5mm jack on an airplane seatback, a hotel TV, a treadmill console — and rebroadcast it over Bluetooth 5.3 to the headphones you already own and like. That is a genuinely useful trick, because airplane entertainment systems and gym machines are exactly the places where your nice wireless earbuds are otherwise useless. The included dual 3.5mm adapter covers both the standard single-plug and the two-plug airline configurations, so you are not stuck hunting for an adapter at 30,000 feet.
The wireless side is where the specs get interesting. aptX-Adaptive support means that when you pair the Relay with a compatible listening device, you get high-quality audio at low latency — the low-latency part matters a lot when you are watching a movie, because it is what keeps lip movements and dialogue roughly in sync. Bluetooth 5.3 gives you a stable, reliable connection rather than a flaky one that drops every time someone walks past. And the case has a battery display, so you can see charge level and charging status at a glance instead of guessing.
On the audio side of the bundle, the Clan N1 earbuds bring hybrid ANC rated to block up to 24dB of environmental noise, plus an Ambient Mode that flips the built-in mics on so surrounding sound reaches you and you stay aware of what is happening around you. That combination — cancel when you want quiet, transparency when you need awareness — is the practical setup most commuters actually want.
TAGRY Hybrid Active Noise: Who It's For
The TAGRY H37 is a very different proposition: it is the whole kit, and it tries to be several products at once. The headline is hybrid active noise cancellation that TAGRY says blocks over 95% of ambient noise, paired with Hi-Res certified audio, 13mm dynamic drivers and Bluetooth 5.4. In plain terms, that is the modern flagship-earbud recipe — a driver large enough to move real air for bass, a codec-and-chip generation new enough for a stable connection, and ANC that targets the low, droning frequencies of commutes and crowded spaces.
The physical design is the more distinctive part. These are open-ear buds built around a lightweight C-shaped ear clip, with an over-ear placement and an open-ear structure. That means no pressure pushed into your ear canal, all-day comfort that does not turn into soreness, and — crucially — situational awareness. You can hear traffic, a coworker, or a boarding announcement while still hearing your music. For runners, cyclists and people who work in shared spaces, that is a feature, not a compromise. The trade-off is real, though: open-ear designs simply do not seal off the outside world the way in-ear tips do, so passive isolation is limited and bass impact depends more on the driver than on a sealed fit.
Then there is the part that makes the H37 unusual: AI-powered real-time translation across 164 languages, with no subscription required, a claimed 0.3-second response and 99% accuracy. The 8-in-1 feature set covers AI dialogue, audio and video call translation, free-talk, voice notes, photo translation and sleep-aid soundtracks. If you travel internationally, work with clients in other languages, or are learning one, that is a capability almost no ordinary pair of earbuds has.
Battery is straightforward and generous: about 7 hours on a single charge and up to 56 hours total with the charging case, with an LED display on the case so you can monitor remaining energy in real time. Touch controls handle music, calls and volume, and the buds pair with phones, tablets, laptops and smart TVs. The package includes the charging case, eartip, Type-C cable and user manual.
Side-by-Side: Which Should You Choose?
• Best for airplane and hotel TV audio → Avantree Relay. It converts any AUX output to Bluetooth, and the dual 3.5mm adapter handles both airline plug types.
• Best for all-in-one listening → TAGRY Hybrid Active Noise. Earbuds, case, ANC, controls and translation are all in the box; nothing else required.
• Best for battery life → TAGRY Hybrid Active Noise. Up to 56 hours with the charging case versus a transmitter whose runtime depends on its own internal battery.
• Best for noise cancellation → TAGRY Hybrid Active Noise, on paper, with hybrid ANC rated above 95% of ambient noise; the Relay's ANC is the 24dB hybrid system on the bundled Clan N1 earbuds.
• Best for staying aware of your surroundings → TAGRY Hybrid Active Noise. The open-ear clip design keeps your ears unsealed, while the Relay's Ambient Mode does the same job through mics on the paired earbuds.
• Best for low-latency movie watching on a wired source → Avantree Relay. aptX-Adaptive and Bluetooth 5.3 are aimed squarely at that use case.
• Best for travel and language barriers → TAGRY Hybrid Active Noise. Real-time translation across 164 languages with no subscription is a genuinely different category of feature.
• Best if you already own great headphones → Avantree Relay. It upgrades what you have instead of replacing it.
In my opinion, the right answer depends entirely on whether you are buying a listening device or a connectivity device. If you already own Bluetooth headphones you like and you fly, travel or use gym equipment regularly, I would buy the Avantree Relay — it solves a specific, recurring annoyance and it does it with modern codec and Bluetooth support. If you want one pair of earbuds that does everything on its own, including open-ear comfort and real-time translation, I would buy the TAGRY Hybrid Active Noise. For most people who just want earbuds, the TAGRY is the more complete purchase; for frequent flyers with a good pair of headphones already in their bag, the Relay is the smarter add-on.
what is hybrid anc earbuds
Hybrid ANC means the earbuds use microphones on both the outside and the inside of the ear to cancel noise. The outer mic samples ambient sound, the inner mic samples what reaches your ear, and the system generates opposing sound to reduce it. Both products here use hybrid noise cancellation — the Avantree bundle on the Clan N1 earbuds, and the TAGRY H37 across its open-ear design.
what is anc earbuds
ANC stands for active noise cancellation: the earbuds actively generate sound waves that cancel out unwanted ambient noise, rather than just blocking it with a physical seal. It is most effective against steady low-frequency sounds like engine drone, air conditioning and road noise. The Avantree Clan N1 is rated to cut up to 24dB, while TAGRY states its hybrid system blocks over 95% of ambient noise.
what are hybrid anc earbuds
They are earbuds that combine feedforward and feedback microphones for noise cancellation, which generally handles a wider range of frequencies than a single-mic setup. In practice you get quieter commutes and steadier bass, at the cost of more circuitry and battery draw. TAGRY also layers Hi-Res audio and 13mm drivers on top, while Avantree pairs its ANC with an Ambient Mode for awareness.
what are anc earbuds
They are wireless earbuds with built-in active noise cancellation, letting you reduce surrounding sound without turning the volume up. Most include a transparency or ambient mode so you can let outside sound back in when you need it. Both the Avantree bundle and the TAGRY H37 offer that cancel-or-listen flexibility, and each is best suited to different jobs — one for wired-to-wireless audio, one for all-in-one listening.
