I love how it changes light. Update: After one year, we had a pair break in the thong area, called the company and they sent a new pair right away. I would recommend this to anybody who is tired of buying new shoes every three or four months because they deteriorated. Creates decent noise isolation (not perfect) but. One issue though, and it could annoy a few users at first. Bluetooth pairing less then 5 secondsExtra USB w/3. Then I have to restart my phone in order to get it pair again! I also use this mic to sing and I get great recordings pairing this with NVIDIA RTX Voice to remove all the noise. For this model I ordered a 10. Plus they run narrow on the toe stramps.
