I purchased it to mount to my rollaway toolchest to be able to service my commuter bicycle on a weekly basis. So it was high time to order a pair for myself and I am truly delighted. If youre looking for a big blockbuster with famous names and a fast-past, over-the-top series of non-stop action, then this is not it. No drivers to install, no software settings, etc. so elegant ?? its not otiginal low quality ??? Funzionamento: ?Queste cuffie non sono in-ear ma bensì degli auricolari tradizionali con supporto ear-hook regolabile per gli sportivi. It?s not too tight but it?s not going anywhere either. YET ANOTHER FANTASTIC PRODUCT FROM POWERTEC. 4 out of 5 stars due to plastic casing where the core locks are located, but 6 out of 5 stars for price!
