Excerpt: I have cycled through a number of ear buds through the years and most recently upgraded to the Shure 315's only to return them for these. For me, I listen to rock/metal and even some country. I love the guitar sound and mids, but when I listen to music I want it to sound like a concert.
Pros: Comfortable, Good Bass, Great Sound, Lightweight
Conclusion: The Sennheiser IE 80 headphones are awesome. I gave it 5 stars in every category except features, because it would've been nice to have a built-in microphone for calls and/or volume and playback controls.
Excerpt: I am using Headphones by Sennheiser every day in my life. At the work to get pleasure by listen quiet, comfartable music. At the home to be inspired by rock, pop, instrumental music.I have never heard th sound like from this Headphones by Sennheiser.
Pros: Comfortable, Compact, Good Bass, Great Sound, Stylish
Summary: I have read varying reviews over just how much better the 80's are. I had the 8's for 2 years and the upgrade was perfect for me. The 80's deliver two solid upgrades over the 8's: better clarity and sub bass.
