Our take

The HiBy R6 III (2025) is the player for a silent, black background, with four DAC chips and a low-noise design that leave nothing buzzing between the notes, exactly what sensitive and revealing earphones need. The sound is neutral and honest, and a switch flips the amp between Class A for the purest sound and Class AB for longer battery. It runs full Android, so your apps just work, and its line out turns it into a source for your desk.

What it'll drive :

Comfortably drives every earphone in the lineup with power to spare.
What the R6 III gives you instead is a clean source: a quiet background and fine detail. That matters most for the sensitive and revealing sets like Letshuoer Mystic 8, which can hiss on a noisy source. And the detailed sets like the Mega5EST reward the extra clarity with more space and nuance.

Streaming & compatibility

Open Android 12 with system-wide bit-perfect audio, so streaming apps run properly and at full quality — Apple Music, Tidal, Spotify, Qobuz, YouTube Music.
The same honest caveat applies: Apple Music on Android won't go fully bit-perfect, so Tidal or Qobuz are the picks if you want the absolute best.

Beyond headphones, it has the connections to be the hub of a setup: a line-out and a coaxial digital output to feed a bigger system, plus USB DAC mode for your laptop and two-way Bluetooth.

It also has genuinely good built-in tuning tools if you like to tweak — a full EQ and HiBy's slider-based sound adjustments — that work across every app, not just the music player.

Power & Battery

Two headphone outputs: 125 mW from the 3.5 mm, 405 mW from the balanced 4.4 mm — ample for any earphone here. The amp switches between Class A (the best sound) and Class AB (longer runtime), so you choose.

The 4500 mAh battery is genuinely good for a player this capable — up to around 13 hours single-ended, closer to 11 on balanced, and it takes about two hours to fully charge with 18 W fast charging.

Distortion is vanishingly low and the noise floor is very quiet, which is the whole reason to reach for this over something cheaper.

What others ask

Is the HiBy R6 III (2025) powerful enough for my earphones?

Yes, with a lot to spare. The HiBy R6 III (2025) puts out 405 mW from the balanced 4.4 mm output and 125 mW from the 3.5 mm, which is far more than any in-ear monitor needs and enough for many easy-to-drive full-size headphones too. The gain settings let you dial it in so you still get fine volume control at quiet listening levels, and with sensitive earphones that matters more than raw watts ever do.

Will the HiBy R6 III (2025) hiss with sensitive earphones?

No, and for me that's the main reason to buy it. Sensitive multi-driver earphones pick up the faint buzz that phones, dongles and noisier players leave underneath the music, but on the HiBy R6 III (2025) the background stays black. Four Cirrus Logic DAC chips and a 126 dB signal-to-noise ratio on the balanced output mean you hear silence between the notes, and that silence is where the detail and space of a good set come from.

Does the HiBy R6 III (2025) change how my earphones sound, or is it neutral?

It stays neutral. The HiBy R6 III (2025) doesn't add warmth or sparkle of its own, it gets out of the way and lets your earphones sound the way they were tuned, which is exactly what you want from a detailed or revealing set. If you do like to shape the sound, the full EQ and HiBy's sound sliders work across every app, not just the music player, and you can flip the amp between Class A and Class AB to hear which you prefer.

Can I stream Spotify, Tidal, Qobuz and Apple Music in full quality on the HiBy R6 III (2025)?

Yes. The HiBy R6 III (2025) runs open Android 12 with system-wide bit-perfect audio, so Spotify, Tidal, Qobuz, Apple Music and YouTube Music all install and play properly. One honest caveat: Apple Music on Android doesn't go fully bit-perfect, so if you want the absolute best quality, Tidal or Qobuz are the better picks.

How long does the HiBy R6 III (2025) battery last, and does Class A mode drain it faster?

The HiBy R6 III (2025) has a 4500 mAh battery that lasts up to around 13 hours from the 3.5 mm output and closer to 11 on balanced. Class A mode does cost you runtime, which is why you can switch: Class A for the best sound, Class AB when you need the battery to last the day. A full charge takes about two hours with 18 W fast charging.

Why buy the HiBy R6 III (2025) when I already have a phone and a dongle?

Because a phone was never built for music. The HiBy R6 III (2025) gives you a blacker background than a typical dongle, a battery that doesn't drain your phone, and room for your whole library on a microSD card up to 2 TB, so you can leave the phone and its notifications in another room and just listen. Both headphone outputs also work as line out, so at home it becomes the source for your desk amp or hi-fi.
