I purchased these due to price drop, therefore I did not pay the "normal" price which is soo high and not justified.
They drop out of my ears even with the running thingie on.
The sound quality is below average. If you enjoy your audio then do not purchase these. The sound quality must have been the last thing on their priority list when building them.
Maybe for listening audio books could work and not for running. Recharging is easy and it helps to be able to recharge from phone. They last around 3-3:30 hours.
I do not recommend in any way.
