The R-80s are wonderful headphones

The sound is REALLY good, as good as phones in the 200 dollar range, in my opinion. The bass is deep, and tight, with presence. And the highs are really clear with no tinny sound. Everyone that hears them comments on how clear they sound. They go plenty loud as well...louder than one can stand. I have long used the Koss Porta Pro headphones because of their portability and supurb sound. (Look them up on here and you will see it is one of the top rated pairs of headphones PERIOD). I have also searched for a long time for a pair of sealed headphones that had a similar sound to the Porta Pros. I searched a long time, and sampled some very expensive cans. But when I heard these R-80s I knew the search was over. They sound very much like the Porta Pros! So if you like the sound of the Porta Pros... and I have never met anyone that has not been blown away from the sound of the Porta Pros... then you will love the R-80s. Another plus is Koss's lifetime warranty. I have used it in the past on other headphones, and they replace with no questions asked.
