Query: Unusable - Distortion

I'd recommend a different brand. This one makes it sound like your speakers are blown (and no - they're not). Playing direct from the CD sounds great. Playing the iPhone into Bose QuiteComfort 15s sounds great so I know it's not the music file on the phone. - it's just when I try to play through the cassette that it sounds horrible.
