Summary: Build quality - I can say that in the 5 years of use the only thing wrong with these headphones were the pads falling apart. And there is a very small tear in the cable sheath near the Y connector. I have never got the gradle sound that some people get.
Summary: The Grado SR-80 has been on pretty much every list of best value in headphones ever made (or at least any that know what they're talking about) and they're there for a good f***ing reason. These are probably some of the best audiophile headphones priced under $150 dollars ever made.
Pros: Everything about this headphone, especially for the price
Cons: Made from cheap materials once you break them down, can be blown out easily if you listen to music loud
Summary: These are great, and actually deserve more credit than I was giving them.
With a view to upgrading, I tried my SR80s out against AKG K701's, and Grado SR225's. If you're interested in what I had to say, check out the thread at http://www.head-fi.org/t/698953/grado-sr80-to-akg-k701-an-upgrade
Pros: Fantastic sound for not a lot of money. Absolutely no regrets in buying mine.
Cons: Look far cheaper than they sound, which can also be said for the SR225's. Read on....
Summary: So, I bought these for my office some years back. They were better than average for office listening, with the open design suitable for not entirely ignoring one's colleagues. I was underwhelmed by the physical design, but listen for a little while and that mostly goes away.
Pros: Amazing sound for the buck -- real lows, real highs with only a bit of harshness on occasion
Cons: Crappy build quality. Cheap foam ear pads which lead to fatigue. The plastic sheathing covering the individual can feeds will crack and cut wires.
Summary: A couple of years ago, I took the bait and bought my set of Grado SR80s. Its been mostly love ever since.
I adore the sound, which is pretty spectacular, especially at this price. Could use a little more robust bass, but i just pump up the bass with EQ. Sound is really clear and musical.
Pros: great sound, light weight, cool retro styling, made in USA
Summary: I've owned a pair of SR-80s since 1996 when my old Yamaha phones collapsed beyond repair. I auditioned a pair of SR-60s at a local high-end store, and when I was ready, got a pair. I was very disappointed! It wasn't at all the sound I had heard in the audition.
Summary: I could not recommend SR-80i's any higher to someone that's looking in that price range.
I did months and months of research before settling for a pair, I read just about every review out there.
Realistically I do not think that for the money you could get yourself a better can.
Summary: Not a review, just my little opinion on these nice headphones.
My Grado SR80s are the older ones (Not the new 'i' version) I'm guessing my SR80s were made around in 2001-2003 etc.
All I can say these SR80s are very musical sounding headphones, and they can sure boogie too.
Pros: Very musical, dynamic, fast and very detailed.
Cons: Can be a bit harsh sounding sometimes. And comfort can be a little rough at times.
