Good value for money
Compared to my Philips in-ear earphones of the same cost the sound is more correct. The highs do not saturate and the bass is present even without the amplification function, with or without it is almost the same, it depends. The power is also there, in clear it is not bad for the price. It's comfortable even if it's a little worn but you get used to it and at least it holds well. It's important to pair it correctly otherwise it sometimes "stalls". I've only been using it for music for the last 2 months as I don't like communicating with headphones, outside it isolates well from outside noise and has good autonomy. I was expecting something less for the price: satisfactory.
