How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a brand-new pair with a full manufacturer warranty and the strongest active noise cancellation, choose Edifier W800BT; if you need LDAC Hi-Res wireless audio and the longest battery life in this comparison, choose Amazon Renewed Edifier W830NB.
• Edifier W800BT — biggest strength: hybrid ANC rated to -44dB, a new-condition 1-year manufacturer warranty, and a light 0.25 kg foldable build with Bluetooth 5.4 multipoint. Trade-off: no LDAC, and 45 hours of playback is the shorter figure here.
• Amazon Renewed Edifier W830NB — biggest strength: LDAC Hi-Res decoding at 990kbps plus 94 hours of playback and spatial audio. Trade-off: it's a renewed unit with only a 90-day limited warranty, and it weighs a bit more at roughly 265–267g.
• Pick the W800BT if you want new-condition hardware, deeper rated ANC, and a longer warranty window.
• Pick the renewed W830NB if LDAC sound quality, marathon battery life, and spatial audio matter more to you than warranty length.
• Both run Bluetooth 5.4, use 40mm dynamic drivers, and are over-ear, foldable designs.
The W800BT Pro is Edifier's new-condition hybrid ANC over-ear, and the spec that jumps out first is noise cancellation: a rated depth of up to -44dB using hybrid active noise cancellation paired with a full-fit over-ear seal. That combination of active tech and passive clamping is what makes a headphone genuinely usable on a plane, a bus, or an open-plan office. If blocking the world out is your priority, this is the more purpose-built of the two.
Around that core, Edifier builds a very practical daily driver. Bluetooth 5.4 gives you faster transmission, stronger anti-interference, and lower power draw, and dual-device connection lets you stay hooked to a laptop and a phone at the same time — handy if you take calls mid-playlist. Speaking of calls, there's an AI call noise reduction algorithm with a high-sensitivity microphone that works to keep your voice intelligible while suppressing background chatter.
Battery life is rated up to 45 hours with ANC off, and a 10-minute top-up is quoted at 8 hours of use — the kind of number that saves you on the way out the door. The build is light at 0.25 kg, with a multi-direction adaptive structure, pressure-relief headband, and soft ear pads, and it folds for travel. There's app support through EDIFIER ConneX for EQ presets and control tweaks. You also get a 1-year manufacturer warranty and a hard box or padded case in the package.
Amazon Renewed Edifier W830NB: Who It's For
The renewed W830NB is the LDAC story in this matchup. It supports LDAC high-definition decoding for Hi-Res Wireless audio at a transfer rate of 990kbps, which Edifier describes as roughly three times the detail of standard Bluetooth codecs. Combined with 40mm dynamic drivers, an independent acoustic chamber layout, and a frequency range extending into Hi-Res territory (40kHz+), this is the pick for someone who cares about what the music actually sounds like over Bluetooth rather than just how loud the room gets quieted.
Noise cancellation is no slouch either: hybrid digital ANC rated to -45dB, described as an 18% improvement over the previous generation, with four ANC modes so you can switch between full cancellation and letting some of the world in. There's also spatial audio via a three-dimensional sound stage algorithm for a surround-style presentation — useful for films and games more than for podcasts.
The headline number, though, is battery. Up to 94 hours of playback with ANC off, and a 15-minute fast charge quoted at up to 10 hours of use. It charges in about 1.5 hours. Calls get Deep Neural Network noise reduction that separates your voice from surrounding noise. The design is ergonomic with soft ear pads and an adjustable headband at around 265g, and it folds for travel. Bluetooth 5.4 and multipoint connection are both on board.
The catch is the "Renewed" label. It's a renewed unit backed by a 90-day limited warranty rather than a full year. Who should buy it: LDAC listeners, long-haul travelers, and anyone who hates charging — and who is comfortable with a shorter warranty. Who should skip it: buyers who want new-condition hardware and the longest possible coverage.
• Best for LDAC / Hi-Res wireless audio → Amazon Renewed Edifier W830NB. LDAC at 990kbps with a 40kHz+ range is the whole point of this pick.
• Best for battery life → Amazon Renewed Edifier W830NB. 94 hours vs 45 hours is not close.
• Best for rated ANC depth → Edifier W800BT... by a hair. -44dB vs -45dB is effectively a wash; the W800BT's advantage is really the new-condition build around it.
• Best for warranty peace of mind → Edifier W800BT. A 1-year manufacturer warranty versus a 90-day limited warranty.
• Best for fast top-ups → Amazon Renewed Edifier W830NB. 15 minutes for up to 10 hours, versus 10 minutes for 8 hours.
• Best for immersive movie/game sound → Amazon Renewed Edifier W830NB. Spatial audio is a feature the W800BT simply doesn't list.
• Best for lightest carry → Edifier W800BT. 0.25 kg versus roughly 265–267g, though both fold.
• Best for new-condition buyers → Edifier W800BT. If "renewed" gives you pause, this ends the debate.
In my opinion, the choice comes down to one question: do you want LDAC, or do you want new-condition hardware? If you're chasing Hi-Res wireless sound and you never want to think about a charger, I'd take the Amazon Renewed Edifier W830NB — 94 hours and LDAC at 990kbps are genuinely hard to argue with. But if you'd rather have a fresh unit, a full 1-year warranty, and don't need LDAC, I'd buy the Edifier W800BT and never look back. Buyers who care about the number on the box should check the current price on Amazon before deciding.
FAQ
what is ldac headphones
what is ldac support in headphones
It means the headphone can decode Sony's LDAC codec over Bluetooth, so it can carry far more audio data than a basic codec. In practice you also need a source device that transmits LDAC, such as a compatible Android phone. The renewed W830NB supports it; the W800BT relies on standard Bluetooth codecs.
what is ldac codec in headphones
It's the encoding layer that compresses and sends audio over Bluetooth, and LDAC is the high-bitrate option within it. Higher bitrate means more musical detail survives the trip. Edifier pairs LDAC with 40mm dynamic drivers and an independent acoustic chamber on the W830NB for that reason.
what is ldac sony headphones
LDAC was developed by Sony as a high-resolution Bluetooth codec, and it shows up across many brands' headphones — not just Sony's. Edifier licenses it for the W830NB. If LDAC is a must-have for you, that's the model in this comparison to pick.
