Query: Annoying sound

Do not buy these unless you have a severe hearing loss in the treble range. The sound is the most unbalanced of any headphone or earbud I have ever heard. The high frequencies are so loud and harsh, you don't have a chance to hear the bass. The sound is thin to say the least, hardly extended bass. Too bad because the construction is so good and they're comfortable. However, I will continue listening through my $12 Koss Clip-On phones. They're great.Jim in Hawaii
