Review: It is a good product highly recommended - It adds the quality of sound from my iphone
Review: Amazing for the money - A lot of these reviews mention a noise. As far as I can tell if you are using the device on battery power (as intended) there is no noise, like a surprising lack of noise. I am very impressed with the quality. However, There is significant noise if you power the device while using it, more so if it is plugged into a digital source like a laptop. The battery lasts about 10-14 hours for me with my 40ohm headphones, and charges in 1-2 hours. The build quality is okay for the price but is nothing to write home about. It feels quality enough to last but lacks some fit and finish. The volume knob has some resistance to it which helps when it is in your pocket. The gain switch works well and this thing can really damage your hearing so be careful. For the price you can’t beat it. Would buy again.

### ⭐⭐⭐⭐⭐ Ottimo e testato sul campo senza problemi
*by J***A on 26 July 2026*

Molto utile per amplificare in ear sul palco durante i concerti, quando necessario. usato per 1 mese in tour e non ha dato problemi. la carica dura sicuramente abbastanza per un set di 1 ora ma penso potesse durare anche di piu'. lo ricaricavo per sicurezza. cmq bravo
