I just got some Momentum's 3 days ago. I have listened to about 5-6 albums and several singles(Tool, NIN, Pantera, Metallica, etc...FLAC, MP3, CD) since then when not at work(and the wife lets me HA!!) and I have to say the earcups are very small(I also have larger than average ears) but what really made them uncomfortable for me was my glasses. It sucks, I have 20/20 vision with horrible astigmatism. Anyway, I found that if I take my glasses off before putting them on then sliding them over the top of the earcups so they are angled down a little it completely gets rid of this issue and I can wear them for hours with no issues. It also makes no difference with vision. I hope this will work for others as well. The Momentum's sounds great to my ears and I thought that the V-moda's were a little bass heavy and not quite as clear as the Momentum's. I am still in my 14 day return policy from the apple store(I hated going in there but what can you do...) but I dont think I am going to return them. I am new to all this so they sound better than anything I have listened to before(dont get on me too bad lol) Right now I am using my HTC m8 to listen to music on the go and my Denon 1705 for home listening. I dont have a headphone amp yet but plan on getting one before the end of the year. What should I look for in a desk amp for these headphones? I also have a set of Bose quietcomfort 2's that were lying around my dads basement for 10 years. He gave them to me and honestly they sound pretty good but not great. The noise cancellation is good as long as the batter is above 25% and I use them occasionally as well. Also I have a set of Logitech g35's for gaming but they sound like butt and I have retired them. I would rather listen is stereo with great sound that 7.1 with awful sound. Thanks for reading this. Any advice would be greatly appreciated.
