Why it is so overcomplicated??
The hardware, battery is great. But. There should be an easy and a difficult kevel version. Not everyone want to do a medical ear test. I purchased it for listening music, nothing more. For this amount of money, I would expect a much better app. Setting the sound type is super difficult. I just want to increase the bass and decrease the mids; I don't want to spend 10 minutes in a lab for a simple adjustment. The firmware upgrade took about 6 minutes. Come on, it's less than 2 MB! I have the Liberty 4 Pro, and I really don’t understand the purpose of the touchscreen. It's too complicated. I just need two buttons. I don't want to feel like I'm hacking NASA through my earphones' touchscreen.
