As an ex pro audio engineer, I take my sound seriously, very seriously! I have spent a lot of money searching for the best earphones to go with my Ipod/Itouch and have been through brands like Sennheiser various models, Shure SE535, Grado GR10, Monster Beats Pro, Bose Quiet Comfort 2 and MIE2I! Whilst trying and giving away to family/friends the above models, I had been using V-Moda Remix and was quite satisfied with the sound. The problem with most head/earphones is that they don't reproduce the the bass frequencies realistically, obviously due to size limitations and it was with discovering V-Moda that changed as they repoduce a thumping bass somehow, although they suffered from flimsy cables and some high frequency distortion. V-Moda's are excellent value for money compared to much more expensive brands and beat them hands down. However, I finally discovered the Klipsch X-10i in 2010 and have not looked back. The sound is fantastic, better than any other earphone I have tried, they fit very comfortably in your ear and never, ever have I suffered ear fatigue even on 12 hour + flights, something I cannot say about Bose Quiet Comfort 2 or Monster Beats which caused ear fatigue after just a couple of hours use.
As the title says, worth the money and I even just purchased another set for my mum who after listening to my X-10i didn't want to give them back :) I had previously given her the Shure SE535 which she didn't like and the V-Moda's which she loved until she tried my X-10i's (don't you just love your mum LOL). My 13 year son drove me mad for Monster Beats Pro (fashion statement) as he did not believe me when I told him to stick with his V-Modas, so he got his wish but has finally realised (he now uses his V-Modas at home and his Monster Beats in public to impress LOL - Kids).
If you can afford $300 for earphones, buy the Klipsch X-10i, if your budget is less, buy the V-Modas. Enjoy!
