The charging got very awkward to a point in which many people are more accustomed to having the case closed to charge up both the earphones and the case at the same time. The first instance that I've received had a fatal flaw on the right earbud in which after fully charging it the battery would drain too quickly, but in reality, it had a mechanical gremlin. Now I'm into my second and more functional (hopefully) instance in which I'm PRAYING that the Left Earbud doesn't lose wanton battery after about 5-10 minutes. If you are more used to "closed clam" charging while having your TW Earphones charged, I would prefer the Klipsch T5 II TW Earphones (which has the same IP67 rating as with these cans), or if you don't mind the constricted IPX4 nerf and if you can afford them, the Klipsch T5 II ANC Earphones, as the T5 II Sport Earphones require a lot of perseverance and respect to tame them.
Sounded great when it kept connection, Stuttered audio due to bluetooth dropout in high bluetooth use areas like my gym. Both with my Samsung S21 and my FIIO M7 and 11 Pros. Then I had the same issue mowing my lawn using the T5s with my S21 as the only bluetooth usage around. My Status Audio BT Transfers at a 1/3 of the $, do not have these issues and sound in the same league as the T5s. Frankly I expected more, was disappointed and eventually retunred them for my $$ back.
I was hoping for an update to the asthetics from the T5 II headphones. To keep the same appearance and add silicone sleeves was a bit of a disappointment. I was expecting the sport model to be slimmer, and more comfortable in ear. These headphones perform well, but their comfort is the low point on my review
I do not recommend it since the one I bought only lasted a week, and it is still the date that they do not return the money. This product has many flaws
