I originally bought these headphones to go with our digital piano, but my wife didn't see any need for them, so they became my computer headphones. Darn :DI want to start out by pointing out that these headphones have a very soft feel on the head, yet are firm enough to not fall off. Sound quality is extremely important to me, not just blasting bass or highs or anything. These have excellent fidelity. You can hear the highs, the lows, and the mids very clearly on this set, and one is not overpowered by the others. One thing I have noticed about lower-end headphones is the fact that when you have too many things going on in music (or games, or movies) some parts start to literally get lost as the headphones simply cannot handle that many streams simultaneously. These headphones do not have that problem. After reading the reviews from people who have enjoyed theirs for ten to twenty years, I look forward to a long relationship with these.I listen to a wide variety of music, and everything from Linkin Park to Mozart sounds great on these headphones, as well as a wide variety of PC games ranging from thrillers where hearing clearly is essential to survival, to FPS games with explosions and gunshots. I have noticed with these phones, I feel like I have my 5.1 system on, and have to take them off to ensure I am not being obnoxious to my neighbors, only to learn that it is simply the quality of the headphones that I am hearing. The same thing happened with our digital piano, I thought I was hearing the piano outside of my headphones as well as inside them, but that was not the case. Anyone who is disappointed by these either has ridiculous expectations, or they do not know what sound quality is.Update 2/15/2013So, I wanted to get on here and make another comment on the comfort and noise reduction. I have put them on when I sat down at my computer, only to realize an hour later I was still wearing them, and not listening to any music. They are comfortable enough to forget that they are on, and the are noise isolating enough that they literally cut the noise levels in the room in half. I continue to love them.Update 1/19/2015I have found a "con" with these headphones... they spoil you. The frequency response is excellent, far better than anything else in the price range. Mine are still going strong with several hours of daily use. The pads are starting to wear out a little, but are still extremely comfortable. I am currently trying to find some speakers for my computer so I can listen while walking around the room, and it is difficult to find something with comparable quality in speaker form. I still love them, and will still sometimes realize I am wearing them and forget that I don't have anything on, just enjoying the quiet isolation that they provide. They still provide excellent sound quality, whether it be games, movies, music, or whatever. I was just playing with a sound generating tool, and I can (barely) hear as low as .9 Hz with these phones... that is incredible for headphones. JUST BUY THEM ALREADY!! :)Update 12/14/2015Just wanted to update that I am still using these headphones, and still loving them. They are by far the BEST headphones I have ever owned. They beat everything I have ever tried in durability, comfort, sound quality, surround reproduction, and price. Honestly, the fact that I am eclipsing my third year with these bad boys says a lot. Rather than having to replace sub-standard phones multiple times in the last three years; I have owned the same pair. And while I don't abuse them, I'm not exactly gentle on them either. I collapse them, wrap the cord around them, then toss them into my suitcase for travel. They are still in excellent condition (sans the pads). The only reason I'm on Amazon right now is that the ear pads just started to flake off a few days ago, so I am shopping for new pads. Again, worth every penny. Especially where they are like $65 right now; I am legitimately considering buying a second pair, especially considering the fact that the pads are $25. again... BUY THESE! YOU WILL LOVE THEM!!!!April 2017... Still love them, still use them daily for hour or more. I even use them while working out. You won't regret buying these.September 27, 2017 -Still absolutely love them. Still sound amazing. Still holding up great. Still incredibly comfortable. Still would buy them again in a heartbeat.February 18, 2018 -Use them daily. Love them. Love love love LOVE them. I had someone suggest to me that I should buy a gamer's headset with a microphone. I pointed out to them that the headphones I use are what professionals use when PRODUCING music... so I wasn't about to give them up... so I bought as mic boom instead :) Unmatched sound, incredible durability. I have gotten more than my money's worth out of these, and they are still going strong.August 8th, 2018 -I am buying a second pair today. Not because the first ones have broken, but because I have a second location for my headphones to travel to, and I would rather have a second pair than take them from one computer to the other. Yeah. They are that good. 6 years old, working great, no flaws... and I'm now going to add my second pair. Fantastic. I truly don't geek out about much... but these are phenomenal headphones. I have never had a set of headphones last 6 years... and they still are GREAT.January 10th, 2019 -Still great. I'm wearing my original pair right now, and they sound just as phenomenal as they did the day I bought them. I will say that the aftermarket pads (unfortunately, I don't remember what the brand was...) are better than the originals, as they have had much harder use over the last three years of use than the first three years of use, and the non OEM pads are still in fantastic condition. I shared some of the concerns mentioned by a few other reviewers about the little cords that poke out the top of the monitors, but 6 years in... no damage. I am considering buying a THIRD pair, so I have a travel set, a permanently plugged into the back of my PC set, and a workout set. Yeah, yeah... first world problems... but I can't bring myself to consider purchasing anything else. These headphones have been fantastic. I have put literally thousands (6,000 plus) of hours on them. Not a single issue, other than replacing pads 3 years ago. I can't say enough good things about these. Sony has had their ups and downs... but these headphones are one of their resounding successes.7/28/2020Still use my original pair almost daily. I am always amazed when I put these on at the quality of the sound (I have a pair of SkullCandy Bluetooth headphones I wear around the house - no cord is nice sometimes.) The sound quality on these still can't be beat; and this is after almost 8 years of ownership. I'll keep updating as I keep enjoying using them.4/16/2021I'm coming back to buy new ear pads for my original pair again. Still fantastic headphones. I ended up buying the third pair. It lives on my treadmill. Although it seems like these may not be buyable right now... if they do come back in stock; buy them. Don't hesitate, stop thinking about it... these are the audiophile headphones you are looking for. I love mine.10/1/2022So I just "retired" my first pair of these. They have been used, abused, flown on multiple flights, used for workouts, not always treated as nicely as one should, but most importantly, used for literally TENS of THOUSANDS of hours. Why did I retire them? They starting having a buzzing in the left ear at some frequencies in the last year. It became just too much for me, especially as I had a brand new pair (my travel pair) sitting next to me at my desk. So now, my original set is my travel set. Because there is no way I'm going to get rid of them. They still sound GREAT, just the mild buzz is a bit too much for daily use. These headphones are LEGENDARY.
