I cant rate how these Crocs hold up wearing yet. Sennheiser opened a new factory in Romania. Aucun bruit nuisible à détecter. Only ever wore inside the home, but look like theyve been used in running a marathon. It does not use the headset, but all audio in/out was using my phone instead. 5 did great for him! The Bluetooth/ApTX connection to these from my phone (a Huawei Mate 10 Pro) has been really strong and stable and I’ve been able to roam around Edinburgh city centre without experiencing any issues with these dropping the connection or stuttering - which is something that absolutely plagues lesser headphones. Bought this for my diva daughter who lives in Georgia. The only bad that I can knock on these are that it seems that it doesn’t get as loud as my air pods and the mic on them makes it sound like you are far away. Because I use them for work 8 hours a day every day, the chance they might not charge overnight isnt acceptable.
