UGREEN Max5 vs HAYLOU S35

UGREEN's 120-hour claim is the headline and it is genuine for music at moderate volume with ANC on; you can forget the charger for weeks. The cost of that is a -48 dB ANC that is good but a step behind HAYLOU's -50 dB, which is the difference between "train goes quiet" and "train mostly vanishes." HAYLOU also runs Bluetooth 6.0 and a 3D spatial mode that widens a stereo track for movies, neither of which UGREEN has. On sound both use 40mm drivers and LDAC, so neither is the weak link. HAYLOU's penalty is the 80-hour battery (still a week of commutes) and the 6 EUR premium, plus no fold-flat. For a desk-or-flight user the quieter ANC and spatial win; for anyone who hates charging, UGREEN's endurance is hard to argue with.

Choose UGREEN Studio Pro if battery anxiety is your main complaint and you want the cheapest LDAC cans that just work. Choose HAYLOU S40 if you fly, watch on the laptop, and want the deeper ANC plus spatial. Most travelers end up happier with the HAYLOU for the quiet alone.
