Query: Tinney, thin,no bass sound!

I was duped again by some decent reviews of this product.Who are these people,do they work for Shure? These were terrible! Once I managed to get them in my ear,(figuring out which was right and left,not marked,)the over the ear wire system is a complete bummer and the sound was mind bogglingly bad, like a cheap transistor radio!
