I have used these earphones for a while now and find them great for hiking as I can listen to a podcast and still hear the sounds of birds in the bush. My only disappointment has been the deterioration of the silicone covers which have softened and now flop around a bit, thus not holding the earphone snugly in my ears. Have put the spare set into use, just hoping I will be able to buy more as I can see they won't last as long as I expect the whole unit to last.

There ok bit big but tbh there the best fitted wireless I have came across bar Apple airpods

I bought this during Christmas season. There were no test piece available even I bought this product. Sound: The sound quality is awesome, exactly with sony digital technology. I can ensure that the one who listens will get goosbumbs. Design: When coming to design, it's unique and the adjustments(play, pause, shuffle and call keys) are quitely designed and comfortable. With NFC technnology it's more easy to connect with upcominng smartphones. Fitting: I'd give 0/5 rating, one of the worst fitting ever I used till now. There were 2 different sizes given but none of them doesn't fit in ear perfectly. It iis designed for sports, but it gets out from the ear even performing simple head moves. Fitting is more important because one couldn't always adjust all time to get complete movie or sound experience. Sony should redesign or change the fitting issues atleast. Charge: The charge time is perfect, it takes 1.30 hours to charge and the bckup time is almost similar to 8 hours (I didn't count).
