Worst headphone.... and also worst app, there is no option of refund to this product.... I hate this product. I would request to all didn't get this product

Replaced some old cheap "JAYS" brand lightweight headphones. I was actually shocked at how bad the Sony ZX110's are compared to the Jays. Voices are muffled, Bass is clearly boosted to the extreme above everything else trying to hide the terrible clarity of the speakers.

These headphones are perfect for low pitch rhythmic noise (eg airplane engine, air conditioner noise, and bass of the music blaring next door). Does not block out higher pitch sounds

These phones sound really nice, for being under $20. I have owned at least 30 different headphones since 1974, and these sound as good as any of the $100 Sennheisers I had back when Elton John's "Rocket Man" was new music.
