• EarFun Air 2 — biggest strength: in-ear active noise cancellation rated to reduce noise up to 43dB, plus LDAC and aptX Adaptive support in a 4.5g-per-bud design.
• EarFun Air 2 — biggest trade-off: it's an in-ear bud, so it relies on a good tip seal and a charged case, and the brand itself notes that keeping LDAC on can cost you some connection stability.
• Avantree HT5009 — biggest strength: it's a complete TV audio kit — over-ear headphones, a low-latency transmitter and a charging dock — with up to 40 hours of playback.
• Avantree HT5009 — biggest trade-off: it's built for the living room, not the street. It uses Bluetooth 5 with no active noise cancellation, and it's a bulkier over-ear design.
• Who each pick is for: EarFun Air 2 for commuters, travelers and anyone who wants one pair of earbuds for music and calls; Avantree HT5009 for people who want loud, clear, lip-synced TV dialogue at home — especially older listeners.
The EarFun Air 2 is a true-wireless in-ear bud, and the spec sheet tells you it was designed to be carried everywhere. Each bud weighs 0.16oz (4.5g), the enclosure is plastic with silicone tips, and four ear tip sizes are included so you can chase a proper seal. Anyone who has owned earbuds knows the seal is half the battle: it decides how much bass you actually hear and how well the noise cancellation works.
On the audio side, EarFun pairs 10mm wool composite dynamic drivers with LDAC and Qualcomm aptX Adaptive, and the set carries Hi-Res Audio certification. The brand's own claim is that LDAC moves roughly three times more data than ordinary wireless earbuds, which reduces the signal degradation that normally nibbles away at detail in a wireless stream. The stated frequency range runs from 20Hz to 40kHz — well beyond what you can hear, but a sign of headroom in the driver design. Interestingly, EarFun also advises disabling LDAC if you want a more stable connection, which is a refreshingly honest note: the highest-quality codec and the most bulletproof signal aren't always the same setting.
Noise control is the other headline. The Air 2 uses hybrid ANC (EarFun calls it QuietSmart 2.0) rated to cut environmental noise by up to 43dB, with selectable modes so you can match the cancellation to your surroundings. For calls, there are six microphones working with Qualcomm cVc 8.0 ENC to lift your voice above background and wind noise. Bluetooth 5.3 handles the connection, and multipoint lets you stay paired to two devices at once — laptop and phone, say — so a call can interrupt your music without a re-pairing ritual. Touch controls cover media playback.
Buy it if you want one compact pair for the commute, the gym bag and the desk, and you care about codec quality and noise cancellation. Skip it if your main listening happens in front of a TV, if you dislike in-ear fit, or if you want a headphone that never needs a charging case.
The Avantree HT5009 Plus is a different species entirely. This is a three-piece system — over-ear headphones, a Bluetooth transmitter, and a charging dock — assembled for one job: watching TV without disturbing anyone else, or finally hearing the dialogue properly. That last point matters more than it sounds. Lots of people don't need "better audio" so much as they need louder, clearer speech, and Avantree built the HT5009 around that.
The clear voice mode boosts on-screen dialogue so you don't miss words, and the overall volume is deliberately pushed up — Avantree names elderly and hard-of-hearing listeners as the target. Both the headphones and the transmitter use Qualcomm chipsets to minimize audio delay, which is the difference between lip-sync that feels natural and lip-sync that feels like a badly dubbed film. If you've ever tried ordinary Bluetooth headphones with a TV, you know exactly how bad that lag can be.
Battery life is rated at up to 40 hours, and recharging is deliberately frictionless: you set the headphones on the cordless charging base rather than hunting for a cable. Pass-through support means audio can play through your soundbar or speaker at the same time as the headphones, so two people can watch together — one at full room volume, one at whatever level suits them.
The bundle also includes a set of replacement earpads made with memory foam, described as durable and long-lasting. That's a small inclusion with outsized value, because worn-out pads are the most common reason a perfectly good pair of over-ear headphones gets retired. The pads are over-ear, the controls are touch-based, and the frequency range is stated at 20Hz to 20,000Hz. Noise control is sound isolation only — there's no ANC here.
Side-by-Side: Which Should You Choose?
• Best for TV and movie watching → Avantree HT5009, thanks to the dedicated low-latency transmitter and lip-sync-focused design.
• Best for commuting, travel and workouts → EarFun Air 2, because 4.5g buds with a case are simply easier to carry than over-ear headphones.
• Best for noise cancellation → EarFun Air 2, with hybrid ANC rated to reduce noise by up to 43dB. The HT5009 offers sound isolation only.
• Best for battery life → Avantree HT5009, rated up to 40 hours on a charge and topped up on a charging dock.
• Best for hi-res codec support → EarFun Air 2, which pairs LDAC and Qualcomm aptX Adaptive with Hi-Res Audio certification.
• Best for hearing dialogue clearly → Avantree HT5009, whose clear voice mode and boosted volume are aimed squarely at that problem.
• Best for calls → EarFun Air 2, with six microphones and Qualcomm cVc 8.0 ENC for voice pickup.
• Best for sharing audio with someone else → Avantree HT5009, since pass-through support lets the speakers and headphones play at once.
• Best for multi-device switching → EarFun Air 2, which uses Bluetooth 5.3 and multipoint to hold two devices at the same time.
In my opinion, these two barely compete — they solve different problems, and the right answer depends on where you do most of your listening. If I were buying for myself as an everyday pair of earbuds, I'd take the EarFun Air 2: the aptX Adaptive and LDAC support, the 43dB ANC rating, multipoint on Bluetooth 5.3 and the 4.5g fit make it the more versatile object. But if the goal is hearing the TV properly — especially for a parent or grandparent — I'd buy the Avantree HT5009 without hesitation. The transmitter, the dock, the 40-hour battery and clear voice mode exist for exactly that job, and no pair of earbuds replaces them.
FAQ
what is aptx adaptive headphones
For TV specifically, the Avantree HT5009 is the better fit. It ships with its own transmitter using Qualcomm chipsets to minimize audio delay, so audio and picture stay in sync, and the charging dock keeps it topped up for up to 40 hours. The EarFun Air 2 is a general-purpose earbud with no TV transmitter in the box.
No. The HT5009 uses sound isolation from its over-ear cushions rather than active noise cancellation. If ANC is a priority, the EarFun Air 2 is the one to look at — its hybrid ANC is rated to reduce environmental noise by up to 43dB, with selectable modes for different surroundings.
Yes. The EarFun Air 2 supports multipoint over Bluetooth 5.3, so it can stay connected to two devices simultaneously and switch between calls and media. That makes it handy if you're working on a laptop but taking calls on a phone without re-pairing each time.
