Hi Tyll,
thanks for the impressions. I was going to buy T5p based on some reviews but now I think I'll pass. Based on your description it sounds like a headphone I'd really hate. One question came to mind: I also read about T5p on Headroom's website, why the glowing review?
www.headphone.com :
"T5p offers brilliant musical detail and pristine high-definition sound quality from your favorite portable player device or computer without a headphone amp required. Magnificent 'listening room' quality sound on the fly anywhere your music matters."
4.5 stars: This headphone is often the best performer at its app/price. It performs well and has no remarkable flaws. It is always a very good value in a particular application."
