If you want a travel adapter that turns any airplane seat's 3.5mm jack into a stable Bluetooth link and can feed two pairs of headphones at once, choose Avantree Relay & SoundJet; if you need true wireless earbuds with hi-res LDAC audio, call clarity and 40 hours of playback for jogging and daily commutes, choose boAt Launch Airdopes 800.
• Avantree Relay & SoundJet — biggest strength: aptX Adaptive & HD transmission over Bluetooth 5.3 with a premium Qualcomm chipset, plus dual-headphone support and up to 25 hours of playback.
• Avantree Relay & SoundJet — biggest trade-off: it is an audio transmitter, not a pair of earbuds. It only works with a 3.5mm AUX source, so it is not compatible with phones, car stereos or hearing aids.
• boAt Launch Airdopes 800 — biggest strength: LDAC high-definition audio, four microphones with AI-ENx call noise reduction, in-ear detection and 40 hours of total playback with fast top-ups.
• boAt Launch Airdopes 800 — biggest trade-off: it is a self-contained TWS earbud with no 3.5mm jack, so it can't plug into an airplane seat's wired audio socket the way the Avantree can.
• Who the Avantree is for: frequent flyers and gym-goers who already own good Bluetooth headphones and want to share in-flight audio with a companion.
• Who the boAt is for: joggers and commuters who want one pair of wireless earbuds to handle music, calls and streaming without wires.
The Avantree Relay & SoundJet is best understood as a bridge, not a headphone. It plugs into a 3.5mm AUX jack — the kind you find on airplane seat-back entertainment systems — and rebroadcasts that audio over Bluetooth 5.3 to your own headphones. The headline spec here is aptX Adaptive & HD, powered by a premium Qualcomm chipset, which matters if you already own Bluetooth headphones that decode those codecs. In my opinion, that's the whole reason to pick this over a generic transmitter: the chipset and codec support are the point, and Avantree has spent two decades in wireless audio building around exactly this use case.
Who should skip it? Anyone expecting it to work with a phone, a car stereo or a hearing aid — Avantree explicitly says it isn't compatible with those. This is a niche tool for wired audio sources in airplanes and, at a stretch, gym equipment with an AUX out. If you want earbuds you wear on a run, keep reading.
boAt Launch Airdopes 800: Who It's For
The boAt Launch Airdopes 800 HiDef is a true wireless in-ear pair built for people who want one device for everything. The audio story is LDAC: boAt's pitch is that LDAC compresses audio more efficiently than AAC or SBC, so the output stays closer to the source. Paired with 10mm dual drivers, that's a reasonable foundation for the kind of bass-forward sound a lot of listeners want — the sort of tuning that makes upbeat playlists and podcasts feel lively on a jog. If you're hunting for something that behaves like deep bass kids headphones for jogging but is aimed at adults, this is closer to that brief than a transmitter ever could be.
Calls are the second pillar. Four microphones with AI-ENx technology work to strip out background noise so your voice comes through in a lounge, a café or a busy office. That's the same problem people search around when they want the best transparency mode wireless headphones for jogging — staying aware of traffic and taking a call mid-run without stopping. The Airdopes 800's answer to that is AI-guided mic cleanup plus in-ear detection, which pauses playback when you pull a bud out and resumes when you put it back.
Battery life is generous: up to 40 hours of playback, and boAt's ASAP charging gives roughly 200 minutes of listening from a 10-minute charge. IPX5 means sweat and light rain are survivable. You also get Bluetooth 5.3 with dual pairing so the buds can hold two devices at once, plus app-based Adaptive EQ by Mimi that tailors sound to your hearing profile and app-controlled active noise cancellation.
Side-by-Side: Which Should You Choose?
• Best for in-flight audio sharing → Avantree Relay & SoundJet. Dual-headphone support lets two people listen to the same movie in sync.
• Best for aptX HD and aptX Adaptive listeners → Avantree Relay & SoundJet. The Qualcomm chipset is the reason to buy it.
• Best for battery life → boAt Launch Airdopes 800. Up to 40 hours versus 25 hours on the Avantree.
• Best for jogging and workouts → boAt Launch Airdopes 800. True wireless, IPX5 sweat resistance and in-ear detection fit movement far better than a plug-in adapter.
• Best for calls in noisy places → boAt Launch Airdopes 800. Four mics with AI-ENx are built specifically for that.
• Best for hi-res wireless codec support on earbuds → boAt Launch Airdopes 800. LDAC is the more advanced option here; aptX plays the same role on the Avantree side.
• Best for personalization and ANC → boAt Launch Airdopes 800. Adaptive EQ by Mimi and app-controlled noise cancellation have no equivalent on the Avantree.
• Best for travelers who already love their own headphones → Avantree Relay & SoundJet. It upgrades what you own instead of replacing it.
If I had to pick one, I'd buy the boAt Launch Airdopes 800. For jogging specifically, a true wireless pair with IPX5, in-ear detection and 40 hours of playback is simply the more useful object — it covers music, calls and streaming in one purchase, and LDAC gives it a real audio argument. I'd only switch to the Avantree Relay & SoundJet in one scenario: I already own excellent Bluetooth headphones, I fly often, and I want to share the seat-back screen with someone next to me. In my opinion, that's a narrow but genuinely valuable niche — just not the one most people are shopping for.
FAQ
Between these two, the Avantree Relay & SoundJet is the aptX HD and aptX Adaptive product — it transmits those codecs from a 3.5mm source using a Qualcomm chipset. The boAt Launch Airdopes 800 uses LDAC instead, which is a different high-resolution codec. Your headphones still need to support aptX to benefit from the Avantree.
Yes — I don't quote prices here because they change often. Use the button on this page to check the current price on Amazon for whichever model you're leaning toward. Compare that against what each one replaces for you: the boAt is a full earbud, the Avantree is an accessory.
It's light and pocket-sized, and Avantree lists gym sessions among its uses, so it travels well. But it isn't worn in your ears and has no water-resistance rating in the specs. For actual jogging, the IPX5-rated boAt Launch Airdopes 800 is the more sensible choice.
Based on the specs, the boAt Launch Airdopes 800 — four microphones with AI-ENx technology are designed to suppress background noise on calls. The Avantree has no microphones described for voice pickup; it's an audio transmitter for listening, not a calling device.
