Conclusion: I've used many headphones in the past and I always thought they sounded awesome. This was true until I bought the Grado SR80i. These sound amazing. Everything is crsytal clear to the ears and detailed. Bass is punchy but not overbearing and the highs and mids are excellent.
Conclusion: Audiophile grade sound with comfortable ear pads. With the open on ear design, these are not for public use because the sound can be heard quite a bit outside of the headphones. These are definitely worth the price.
Conclusion: The Grado SR80i headphones are the beat pair of headphones that I've ever owned, and I have owned many pairs of high-end headphones. These have by far the most superior sound quality available for this price range, and even look pretty cool too.
Conclusion: This set of headphones delivered exactly what was promised; great sound, superb clarity (IMHO), and good comfort. The only thing to keep in mind is that the open foam means others in the room will hear some...aka not the best choice for airplanes.
Conclusion: I grew very tired of the cheap quality of a 'Big Box' store $30 headphones. I researched different options and ran across the Grado SR80I. The quality of sound is very good. I had a minor issue with one of the ear piece's shaft.
Conclusion: I have owned many headphones, but the Grado Prestige SR80i is the best by far of them all. It is also the Top Choice in it's category at Consumers Reports! Try it, and you will never let it go. Guaranteed
Conclusion: Works great with digital format players. Low static distortion and very precise with accurate beat and tone emulation. Works fairly well with DAC under low wattage. But tend to shine with .wav and .mp3~4.
