We started by creating Amazing Bass, and then tuned the mids and highs to what we think is perfection. With many top-end headphones, you have to turn the volume up too high to really get the bass you want, because they are very 'mid-range heavy'. And then the highs are too harsh for dance / electronic music. We tuned PUMP specifically for lovers of Electronic and Dance Music, although they sound pretty incredible with ALL genres according to Customer reviews and Artist reviews!
Only had them for a few days and the sound is amazing. The only downside is that they only came with silicon earbuds. The last set I purchased had the memory foam earbuds as well which I find a much better fit. Still amazing though.
I had to return my Mix headphones and asked that I receive a replacement as quickly as possible. Pump Customer Service helped me out very quickly and I had a new pair of Mix headphones within two weeks :)I love these headphones!
Bought these for my son for Christmas who loves them! I've gotta buy another set for my daughter now!
I have nothing else to say than, to this point these are the best in-ears i have used.
