Kromer Radio / Rip-off!
I purchased a pair of Sennheiser earphones and was not allowed to try them on or try a demo pair, which the salesman stated was for hygiene reasons. They were $160 plus tax.
When I went home and tried the headphones, they were incredibly uncomfortable. In order to have the sound-blocking qualities the salesman had claimed they have, they had to be inserted deeply into the ears, resulting in an intrusive poking sensation. The sound quality was not particularly strong, especially at the base end.
Kromer Radio refused to provide a return of the product in the original packaging with receipt. Worse, they were rude and condescending.
