Received very quickly, as usual with Amazon, this helmet meets all my expectations. The sound quality is at the rendezvous (ie SONY) with real bass present and the tips are really varied sizes (S to L), not like a Philips I returned two days later, so the Sound quality was poor and too big tips for even the S. The connection is made via Bluetooth as well as NFC. I've connected a laptop and a smartphone with multiple connection. For the price more, go for it!
