If you want true wireless earbuds with planar magnetic drivers and adaptive noise cancellation, choose Edifier NeoBuds Planar; if you need a way to turn an airplane seat's 3.5mm jack into a low-latency aptX Adaptive wireless link, choose Avantree 2. These are two very different products solving two very different problems, and the aptX Adaptive thread that connects them is worth understanding before you spend anything.
• Edifier NeoBuds Planar — biggest strength: a 12mm planar magnetic driver with Hi-Res Wireless certification, Snapdragon Sound, and a 20Hz–40kHz frequency range, plus adaptive ANC and multipoint pairing.
• Edifier NeoBuds Planar — biggest trade-off: it's a closed earbud system, so it only helps you with sources it can pair to over Bluetooth — it can't rescue a wired-only seatback screen.
• Avantree 2 — biggest strength: it converts a 3.5mm or dual-prong airplane jack into a Bluetooth 5.4 aptX Adaptive transmitter, with an OLED screen so you can see pairing status instead of guessing.
• Avantree 2 — biggest trade-off: it's a transmitter, not a listening device — it produces no sound on its own and needs headphones that support the same aptX Adaptive codec to get the full benefit.
• Who each pick is for: Edifier NeoBuds Planar for music listeners, commuters, and remote workers who want one pair of earbuds to do everything; Avantree 2 for frequent flyers and gym-goers who want to use their own headphones wirelessly with legacy 3.5mm gear.
The NeoBuds Planar is built around one headline decision: a 12mm planar magnetic driver instead of the dynamic drivers most earbuds use. Planar magnetic drivers are usually associated with large over-ear headphones, so putting one in an in-ear shell is the whole point of this model. Edifier pairs it with Hi-Res Wireless certification and Snapdragon Sound support, and quotes a frequency range of 20Hz to 40kHz with 16 ohm impedance. If you care about treble detail and a clean, balanced presentation rather than a bass-heavy tuning, that spec sheet is aimed squarely at you.
The rest of the feature set is about living with the earbuds all day. Adaptive active noise cancellation tackles traffic, office chatter, and household noise, and dual microphones with noise suppression handle calls and meetings. Multipoint pairing lets you hold two devices at once — phone and laptop is the obvious combination — and switch between them without re-pairing. Bluetooth 5.4 with a quoted 10-meter range covers normal room-to-room movement. Latency is listed at 80 milliseconds, which is fine for music and video and casual gaming, though competitive players will notice it.
Who should buy it: anyone who wants a single pair of earbuds for commuting, calls, and music, and who values a planar driver's character over the usual dynamic-driver thump. Who should skip it: if your main listening source is an airplane seatback screen or an old gym machine with a headphone jack, these earbuds can't plug into it — that's a job for a transmitter, not earbuds.
Avantree 2: Who It's For
The Avantree 2 is not headphones. It's a Bluetooth 5.4 audio transmitter built on a Qualcomm chipset, sold as a two-pack, and its reason for existing is the 3.5mm headphone jack that still lives on airplanes, treadmills, and older TVs. Plug it into that jack and it broadcasts the audio wirelessly to your own headphones or earbuds. It supports both single 3.5mm AUX and dual-prong airplane jacks, which is the detail that matters on a long-haul flight — you don't need to carry a separate adapter.
The feature that separates it from cheap transmitters is the OLED screen. It shows pairing status and connected device info, which turns Bluetooth pairing on a plane into something you can actually read rather than a sequence of blinking lights and guesswork. That sounds minor until you're doing it in a cramped seat with the cabin lights down.
Sound quality depends on the codec handshake. The Avantree 2 supports aptX Adaptive, and Avantree is explicit that you get the low-latency, high-quality link when your headphones support the same codec. Pair it with headphones that don't, and you fall back to whatever both ends can agree on. It also supports Auracast, so you can stream to multiple headphones at once or to compatible Auracast hearing aids — useful if you're traveling with a partner and both want to watch the same in-flight movie.
Who should buy it: frequent flyers, gym users, and anyone with wired-only audio sources who wants to use their own wireless headphones instead of whatever the airline hands out. The two-pack means you can keep one in a travel bag and one at home. Who should skip it: if all your audio already comes from Bluetooth devices, this adds nothing. And if your headphones don't support aptX Adaptive, you won't get the codec benefit Avantree is advertising — you'll get a normal Bluetooth connection.
• Best for sound quality as the primary goal → Edifier NeoBuds Planar. A 12mm planar magnetic driver, Hi-Res Wireless certification, and a 20Hz–40kHz range are the specs that matter here.
• Best for airplanes and legacy 3.5mm sources → Avantree 2. Dual-prong and 3.5mm AUX support is exactly what seatback entertainment needs.
• Best for noise cancellation → Edifier NeoBuds Planar. Adaptive ANC is a core feature; the Avantree 2 has no noise cancellation of its own.
• Best for battery life → Edifier NeoBuds Planar. 30 hours quoted total playback, with wireless charging in the case.
• Best for low-latency wireless audio from a wired source → Avantree 2. aptX Adaptive plus a Qualcomm chipset is the point of the product.
• Best for switching between phone and laptop → Edifier NeoBuds Planar. Multipoint dual-device connection is built in.
• Best for sharing audio with someone else → Avantree 2. Auracast support lets multiple headphones receive the same stream.
• Best for a traveler who already owns good headphones → Avantree 2. It upgrades what you have instead of replacing it.
In my opinion, these two shouldn't really be competing for the same slot in your bag, because they solve different problems — but if I had to pick one, I'd buy the Edifier NeoBuds Planar. It's a complete listening product: planar driver, adaptive ANC, multipoint, 30 hours, wireless charging. It replaces a pair of earbuds you already own and improves almost everything about daily listening. The Avantree 2 is the smarter buy only if your specific pain point is a 3.5mm jack you can't get away from — a plane seat, a gym machine, an older TV. If that's you, it's genuinely useful. If it isn't, you'll never use it. Check the current price on Amazon for both and decide based on which problem you actually have.
what is aptx adaptive headphones
aptX Adaptive is a Bluetooth audio codec from Qualcomm that adapts its bitrate and latency to what the connection and the content need. On headphones, it means you can get higher-quality audio for music and lower latency for video or gaming from a single pairing. Both products here are relevant to it: the Avantree 2 transmits in aptX Adaptive, and your headphones need to support the same codec to take advantage of it.
No, but you won't get the codec's benefits without them. Avantree states the low-latency, high-quality link works when paired with headphones that support the same aptX Adaptive codec. With non-supporting headphones, the Avantree 2 still works as a Bluetooth transmitter — you just fall back to a standard connection.
No. They're wireless-only earbuds with no headphone jack. For a seatback 3.5mm or dual-prong jack, you'd need a transmitter like the Avantree 2 to bridge the wired source to the earbuds over Bluetooth.
The Edifier NeoBuds Planar, clearly. Adaptive ANC for traffic and office noise, dual noise-suppressing microphones for calls, and multipoint for switching between phone and laptop are all built for exactly that. The Avantree 2 is a travel accessory, not a daily listening device.
