COOLBOX Wireless sports in-ear headphones with microphone COOLTWIN-DUAL-DRIVER MGS0000008031

The CoolTwin are very comfortable in-ear headphones with an elegant
design and great sound quality thanks to Dual
Driver technology.

Thanks to their light weight and secure fit (3 sizes of
ear tips are included), they are a great choice for listening to music
while running or working out at the gym. They also
feature a hands-free function so you can pause the music and
answer a call simply by pressing a button, for example if
we are listening to the radio while cooking.

But their exceptional sound quality means they are not only
practical headphones to use in these kinds of situations, but
also for enjoying your favorite video games, series or films at your leisure
thanks to Dual Driver technology.

Finally, the braided, tangle-resistant cable is a welcome advantage
for the user, as it prevents the annoying knots that form in
traditional headphones when taken out of a backpack.
