Love these have been buying them for years. They support my 90+ pound Hobie tandem kayak well and save its gunwales from direct contact with the hard metal surface. these are using a Qualcomm technology called TWS Plus as opposed to the standard TWS. Thankfully, youll be speaking more towards the middle/upper part of the microphone. Easy to put on too. My son absolutely love the case and deems it perfect and exactly what he wanted. Overall 4/5: One major problem I have had with this Headset is that its plastic breaks (Where it stretches from) eventually, I personally dont adjust to its size and have it in all the way in, but it tends to happen a lot of the time. the leather is very thin, I expect they will not last long under my abuse, but that is still to be seen. 0 inches in the middle; 8. I should have gone with what other reviews said the first time.
