How long is the helmet covered by warranty? The ear pad has come loose from the rest of the helmet.
I managed to connect it to my Windows 11 computer without any problems, but now the computer no longer recognises it! Strange...
I don't understand...
Otherwise, it connects fine with my tablet and my phone.
Good value for money with helpful advice from the salesperson.
Everything went well.
Excellent value for money regardless of the colour chosen, which is not the case on all websites and/or local shops. The sound quality perfectly meets my expectations, with wired and Bluetooth connectivity, not to mention comfortable compatibility with hearing aids. Top notch.
Robust, durable headphones. Bluetooth or wired l'cancel noise is so practical. The family has them all.
A practical and useful purchase. The sound is great, and the cancel noise very useful for moments of concentration.
The helmet is a bargain in terms of value for money.
Very comfortable and the quality is great!
You'll need to download the app to configure it to your needs :)
Just what I expected.
A little tight on the head, but that's fine.
Excellent sound and insulates well.
I'm disappointed with the sound because it's choppy at times and the sound isn't as clear as I thought it would be... shame about the price...
Good soundproofing and exterior appearance. Lightweight and good audio. Battery ok, received on time and in the right colour!
