Very sophisticated but in my humble opinion there should be settings depending on your environment. So if I am in a loud environment and need to hear the person 3 feet from me, I can hit a setting to enable me to hear their voice above all. Or if I am at a concert I can hit a setting within the app and I can get a good balance for the music. Currently, I have to go in and manually manipulate the settings which takes a long time and I do not have experience in audio manipulation (the app is quite technical).

Terrible design, terrible results, misleading description. Product description says Works with iPhone and Android. False. Doesn't work with other. Has an app that can be used with Android (can't say for iPhone) BUT, never disclosed until you get the product, It does not work with the devices, it works with the CASE. No adjustment of anything at all can be made while the devices are in use. Have to take them out, put them in the case, try something, take them out and reinstall them in your ears to see what happened, if anything. There was NO WAY I could adjust them to not have terrible feedback. Even a very low volume, specially adjusting, with the advice of their customer service, turning down the high frequencies, being sure my ears were clean, trying all of the supplied tips; in other words a lot of work, resulted in feedback. Returning. I am sad because I figured that at this price point I could get something good.
