UGREEN Max5 vs QCY H3 Pro

The UGREEN's 120-hour claim is the headline and it holds for music at moderate volume with ANC on; you can forget the charger for weeks. The cost is a -48 dB ANC that is good but a step behind the QCY's -56 dB, which is the difference between "train goes quiet" and "train mostly vanishes." The QCY also runs Bluetooth 6.0 and a 3D spatial mode that widens a stereo track for movies, neither of which the UGREEN has, and its dual-driver setup adds a bit of headroom. On codecs both use LDAC, so neither is the weak link. The QCY's penalty is the 102-hour battery (still two weeks of commutes) and the slightly higher price, plus no fold-flat. For a desk-or-flight user the quieter ANC and spatial win; for anyone who hates charging, the UGREEN's endurance is hard to argue with.

Choose the UGREEN Studio Pro if battery anxiety is your main complaint and you want the cheapest LDAC cans that just work. Choose the QCY H3S if you fly, watch on the laptop, and want the deeper ANC plus spatial audio. Most travelers end up happier with the QCY for the quiet alone.
