Snug fit. Excellent sound. Very happy!
Pauline B.
Needed to change the ear adapter to get the correct fit, then all the actions to work the buds became very natural.
JEAN-PIERRE D.
Appareil de qualité, excellente musicalité et très pratique en utilisation nomade.
Valter C.
The headphones are enough good but when I put in my ear they are a bit not comfortable because I got small ears and the product is a little big too.
Stefan K.
A bit of getting used to, but once you get the hang of it they are perfect.
Liam H.
Sound quality is flawless as expected. Considering there are pods which cost twice the price and are half the quality these are great value for money..
Denys H.
All right.
Andrius P.
At first sight, disappointed. Poor quality saund. But then firmware update and some settings change and you have high quality saund on the go. Nice fitment and comfortable wear for hours. First quality purchase of TWS earbuds and will recommend it.
