I have use the second pair for a couple of months now and loved them. I have given the product a 4 star rating based on the device performance but if sound fidelity is important to you then helmet choice will play a big part in the quality of the sound that you hear. I use these in my closet to hang my jewelry. Best part: I can wash them off after my walk and theyre dry the next day. Passé le défaut du grave, l?image sonore est agréable voir flatteuse mais reste un peu étouffée et manque d?ouverture dans tout le spectre et de précision dans les aiguës. Memory bandwidth increased by 27% and there were other significant improvements including a 5. I will be keeping both. Pour moi, il ny a vraiment pas mieux. However for bass enthusist, these might be lacking. And its actually IPS waterproof, wont risk it but good to know slight water/rain wont impair function or affect it!
