Query: Poor Low grade FM/cordless phone audio, Thin distorted bass

After owning a pair of Sony MDR-V900 for well over 10 years I thought it a good time to break down & upgrade to the advances made in the last decade with a dive into `wireless technology'. Unfortunately what I received upon the $170 purchase of these "top of the line" headphones was thin bass free, static laden audio that was sub FM sound quality at best. The reception on these is worse than my cordless phone (I live in a small apt & the sound fades if I walk into my bedroom which is well under 50 feet away!). These might be ok for soft-core listeners who might need to run to the kitchen for a snack while watching a movie or something but not for anyone who takes music listening a bit serious (my beat old Sony's still sound better by far!). To boot these are constructed out of plastic that is the quality of milk jugs & the audio channels (R/L) are backward.Hope I can break even on eBay...
