A huge surprise!

'Most:
'A sound rich bass and treble!
'Very strong!
'Very comfortable, with many parts of synthetic leather.
'Jack Supplied with 2 cables (one spiral, normal) + adapter jack 3.5> 6.3 gold plated.
'Locking system jack on the headset cable (note the first branch cable may not fit is that it must rotate once on it to activate the lock and prevent the cable to dispose of cases of shock).
'Comes with a handy little bag for transport.
'The helmet earphones can be rotated 180 ° when the headset is worn around the neck.

'The -:
'A design a little "cheap" which can put off at first ...

'In Short:
A huge surprise with this helmet from Auna! I expected a little cheap headphones in view of its design and I must admit that I am more than pleasantly surprised to find at this price headphones with a good sound quality!
It covers well the ear (takes even warm in winter) completely isolated from ambient noise and delivers quality sound (tested on a train, it's perfect!): This is all that is expected of a helmet audio at this price!
I recommend warmly!
