"Muffled sound with mono earpiece"2.5 starson by dwoliver
Pros: I bought this listening to music with the supplied wired stereo earbuds and it sounds good with them. Good battery life.
Cons: Poor mono sound. Proprietary connector for stereo earbuds so you can not upgrade.
Summary: Trying to use it as a mono earpiece for the phone is a challenge. No high frequencies at all and only moderate volume at max. Mono earpiece is one size only and does not fit my ear.
