Graphene Coated Drivers
Compared to traditional drivers, graphene-coated drivers are lighter, are more precise and have excellent conductivity which the requires less power to drive. This means that no matter what genre of music you listening to, the bass, mids and high tones are clearly defined with low distortion.

Perfect fitness partner
by Vicky_rebel on 31/08/2018
I have tried lots of different wireless headphones/earphones this year and finally I have discovered the perfect pair in these. They literally tick every box and are an absolute bargain if you compare them to other well known brands.

Amazing fit, they do not move/fallout or need adjusting during exercise
Outstanding battery life, you get around 10 hrs per charge
Solid design that is lightweight
Good bluetooth signal
Easy to use controls
Strong magnets in earbuds so you can wear them around your neck
Good sound - not incredible, but if your working out do you really need an audiophile experience?

None! Quite simply these are (for me) the best wireless headphones for sport/gym use
