've been using multiple bluetooth earbuds for the past 5+ years and I finally got the one I most like! I have a similar product but that one doesn't have a case cover like this one. The problem about not having case cover is that the earbuds get dusty very easily. Some may say it's convenient without the cover to take the earbuds out or put them back in but I like having more protection for these amazing sounding earbuds.
I always try to listen to the music at the highest bit-rate as possible and this pair of earbuds just blew my mind! There is virtually no distortion for either high or low frequency and the mid tone is well balanced. They are very light-weight so I had no problem listening to music for a long time.
Charging is quick and it seems like it charges for about 30+ mins for 4+ hours of play. I haven't encountered the time when I have to charge the case from 0 to 100 yet so I'm not sure if it can play 35 hours of time. Just so you know it's not a continuous 35 hours of play. That's the only thing I'd somewhat point out. It's not misleading but you will need to charge them between every 4-5 hours of continuous play.
The case is well built and the quality of the magnets used to hold the earbuds inside the case is exceptional.
I'd highly recommend this to anyone who's looking for True Wireless Earbuds.
