I have had the JBL Endurance Peak for 2 weeks and have only used them 4 times (that's how many times i have been out jogging). The sound is very good and i don't mind the connectivity issues for the price. However, all of the sudden the left ear bud will not charge at all and that can not be expected of any earbud within such a short period of time.
The Good: the wraparound style made for the first set of earbuds in my life that didn't fall out of my ears while running.
Really were great to start. The best over ear buds on the market, but then the left earbud stopped working. It seems like it has a bad connection and crackles, but the earbud won't work, even after a factory reset.
Have had these for about a week and am super impressed! Not the loudest headphones but the volume is adequate. Granted, I listen as loud as possible when working out but took a hike the other day and it was perfect. Having said that the sound clarity is really good especially considering these are Sport earbuds. I think a lot of the negative reviews don’t actually take that into account.
