How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

• AOC's biggest strength: it is a true dual-mode tool — Bluetooth 5.4 for daily listening plus 3.5 mm and 6.35 mm jacks for amps, mixers and wired gear, with a 20 Hz–40 kHz frequency response and 72 hours of playtime.
• AOC's biggest trade-off: it is a full-size over-ear (pink ABS/PC and leather build) with no active noise cancelling, so it is bulkier and less isolating on a commute than a sealed in-ear.
• Ugreen's biggest strength: hi-res certified LDAC at up to 990 kbps (96 kHz/24-bit) plus up to 55 dB adaptive ANC, six mics, spatial audio and Bluetooth 6.0 — a lot of modern audio tech in a tiny shell.
• Ugreen's biggest trade-off: there is no jack at all, so it cannot plug into a guitar amp or wired monitor chain, and the 50-hour figure is total battery with the case rather than one continuous run.
• Pick AOC if you record, mix, practise guitar or want one headphone that works wired and wireless.
• Pick Ugreen if you want hi-res wireless sound, deep noise cancelling and a pocketable fit for commuting, calls and workouts.
The AOC Over Ear is best understood as a studio monitor that happens to have Bluetooth. The 40 mm dynamic drivers cover 20 Hz to 40 kHz, and the spec sheet lists a 108 dB ± 3 dB sensitivity with 32 ohm impedance — numbers that tell you it is easy to drive and loud enough to be useful for tracking and casual monitoring alike. The build is ABS, polycarbonate and leather with oval over-ear cups, and the Bluetooth 5.4 radio reaches about 10 metres.
What makes it different from almost every other wireless headphone is the wiring. You get a 3.5 mm jack and a 6.35 mm jack, plus a 3.9 ft 3.5 mm-to-3.5 mm cable with an in-line mic and a 4.9–9.8 ft 3.5 mm-to-6.35 mm coiled spring cable. That means it can go straight into a guitar amp, a mixer, an audio interface or a PC without an adapter. AOC also notes you can connect a second pair of headphones through those same ports, which is genuinely handy for silent practice or sharing a mix.
Battery life is the other headline: 72 hours of average life with a 2.5-hour charge. That is days of listening on a single top-up, and because it works passively over a cable, a dead battery never locks you out.
Buy it if you record, mix, stream, practise guitar, or want one pair that moves between a desk, an amp and a phone. Skip it if you mainly want to disappear into your own bubble on a noisy train — there is no ANC here, and a full-size headphone takes up bag space.
Ugreen EchoBuds Plus: Who It's For
Noise cancelling is the second pillar. Ugreen pairs adaptive ANC with physical isolation for up to 55 dB of reduction, and an AI chip separates ambient noise in real time. Practically, that is bus, metro and open-office noise handled — the exact places where a sealed in-ear beats an over-ear without ANC. Six microphones with AI noise reduction and wind-noise handling cover calls.
Connectivity is current-generation: Bluetooth 6.0, about 10 metres of range, dual-device pairing so you can jump between phone and laptop, and latency as low as 80 ms for games and video. Battery is 50 hours total from a 600 mAh case, with 10 hours per charge with ANC off and 6.5 hours with ANC on; a 10-minute top-up returns about 4 hours. The app adds eight EQ presets, four ANC modes, a game mode and a spatial audio toggle. IPX5 with nano-coating covers sweat and light rain.
Buy it if you commute, take calls all day, train, or want hi-res wireless sound with custom EQ. Skip it if you need a wired connection to an amp, interface or monitor chain — there is no jack, and the earbuds are grey in-ear sticks, not over-ear cups.
• Best for wired studio and amp work → AOC Over Ear Headphones. The 3.5 mm and 6.35 mm jacks plus the coiled spring cable are the whole point.

• Best for calls on the move → Ugreen EchoBuds Plus. Six mics with AI noise reduction and wind handling.
• Best for silent guitar practice and shared listening → AOC Over Ear Headphones. The second-headphone port and 32 ohm impedance make it easy to drive from a small amp.
• Best for workouts → Ugreen EchoBuds Plus. IPX5 with nano-coating and a lightweight in-ear fit.
• Best for sound tweaking → Ugreen EchoBuds Plus. Eight EQ presets plus spatial audio and four ANC modes in the app.
• Best for a single do-everything pair at a desk → AOC Over Ear Headphones. Bluetooth for casual use, cables for everything serious.
• Best for travel and pocket carry → Ugreen EchoBuds Plus. A case and two tiny buds beat a full-size headphone in a bag.
Worth saying plainly: price is the one thing neither spec sheet settles, so check the current price on Amazon before you commit — the gap between these two categories is often wider than the feature lists suggest.
My Verdict
In my opinion, these two are not really competitors so much as two answers to different questions. If your world involves an amp, an interface, a mixer or a DAW, I would buy the AOC Over Ear Headphones — the dual 3.5 mm/6.35 mm jacks, 40 mm drivers, 32 ohm impedance and 72-hour battery make it a legitimate wired tool that also happens to be wireless. If your listening happens on buses, in offices and at the gym, I would buy the Ugreen EchoBuds Plus — 55 dB ANC, LDAC hi-res streaming, six-mic calls and Bluetooth 6.0 simply cover more of that life. If you can only own one and you are not a musician, the Ugreen is the safer everyday pick; if you are a musician, it is the AOC, and it is not close.
what is hi res headphones
Hi-res headphones are built to reproduce audio beyond the range of a standard CD-grade signal, so they can carry more detail in the highs and tighter control in the low end. On paper the giveaway is the frequency response figure: the AOC Over Ear is listed at 20 Hz–40 kHz, while the Ugreen EchoBuds Plus is listed up to 40 kHz. The wider the range, the more headroom the driver has for high-resolution material.
what is hi res audio headphones
Hi-res audio headphones are the playback half of a hi-res chain — the source file, the codec and the headphone all have to support it. The Ugreen EchoBuds Plus is hi-res certified and decodes LDAC at up to 990 kbps at 96 kHz/24-bit, which is the wireless link that usually limits quality. The AOC Over Ear takes a different route: it is listed with a 40 kHz frequency response and reaches full quality over its wired jacks.
what are hi res headphones
They are headphones designed to resolve more information than a standard Bluetooth stream carries, so quieter details, cymbals and reverb tails stay intact instead of being flattened. Size is not the deciding factor — the Ugreen EchoBuds Plus is a tiny in-ear with LDAC and a 12.4 mm driver, while the AOC Over Ear is a 40 mm over-ear with wired jacks. Both are aimed at the same goal by different means.
which headphones support hi res lossless
For true lossless-grade wireless, the Ugreen EchoBuds Plus is the one to look at: it is hi-res certified with LDAC decoding at up to 990 kbps and 96 kHz/24-bit, and it also supports AAC and SBC for compatibility. The AOC Over Ear supports hi-res through its wired 3.5 mm and 6.35 mm connections rather than over Bluetooth. If lossless over a cable is acceptable, either works; if you want it wireless, pick the Ugreen.
