I'll start with links for reference: O2 Amp: https://www.massdrop.com/buy/massdrop-o2-amplifier TH-X00 Headphones (Purpleheart): https://www.massdrop.com/buy/fostex-x-massdrop-th-x00-purpleheart-headphones    I was wondering if anyone had experience with these devices and could recommend a...

Yeah i found them used for 170 i think. But could i use the UE custom mic cable with them? it seems much sturdier.   http://ultimateears.logitech.com/en-us/ue/custom-in-ear-monitors/accessories   48" Black Cable with Inline remote and Microphone (After September 1, 2010)

thanks, that's what i'm seeing. the UE TF10's come in a version with a mic for 350. you think they're still better than the Westone 4's? those come in at the same price without a cable though :/

I've have a pair of Ultrasone Pro 900's for the past two years and I love them. However, I've recently upgraded my apartment's sound system and I don't need them at home anymore. So I plan on selling them off and getting in-ears for on the go. I would like phone controls (i use a beats...

So right now I have two pairs of speakers. I have inherited both so please don't hate on me for the brands. One is a Logitech Sub that uses RCA connections that now go to Bose Acoustimass Cubes instead of the original logitech speakers. The other(the one i want to upgrade) is an Onkyo...

So this is the situation. I am buying earbuds for a friend. She currently has beats solos (ugh.) that someone bought for her. She loves my Ultrasone Pro 900s but i can't afford to get her those :P and she would prefer earbuds. She mostly listens to Pop and Acoustic music. So far I have been...

So I've had the Ultrasone 900s and the iBasso D-Zero for a few weeks so i thought i'd come back and report. firstly, thanks all for the help! And I absolutely love these headphones, I can finally listen to something other than Hip Hop loud! All genres of music sound amazing honestly. Although...

If you use a Line Out Dock from an iPhone/iPod to connect to an external DAC/AMP wouldn't the battery life of your iDevice be better since the external DAC is doing the converting as well as powering your headphones?   I have run my iphone straight to my headphones and notice the battery...

Thanks for all the info! I've already ordered the iBasso D-Zero will that be worse than the E7 with ultrasone 900s?

thanks for all the help guys. if i can sell my beats i will go ahead and get the Ultrasone 900s and the E7 amp. I'll report back if i do!

Alright sounds good. One last thing though. Is there any advantage to me getting the http://www.amazon.com/FiiO-E7-Portable-Headphone-Amplifier/dp/B003E6K1VK/ref=sr_1_1?ie=UTF8&qid=1324812096&sr=8-1  E7 instead? people are talking about inputs being the issue. I would like to use the Pro 900s...

I can't swing that much unfortunately  but with the Pro 900s without an amp will they sound even worse than the Beats? And then on top of that any suggestions on the the cheapest possible portable amp available that will get the job done?

Yeah I am leaning towards the Pro 900s. also would you mind giving me a brief explanation of what you mean by harsh treble and what pre-burn in is? I'm a bit new to headphones. also your opinion on  Ultrasone PRO 900s or Grado Prestige Series SR325is for all types of music if you had to choose one

@CdC all i have is best buy and the best cans they have are the studio beats... wish i could though   would anyone know if i need an amp for the 900s?   also @WoahReQQuiem would you know if the 900s still have good mids and highs even if not the best because that would be fine, its just...

Hi all, I am not an audiophile by any means so I don't really know anything about headphones so bare with me. I know people hate this but right now I have Studio Beats and I'm looking to upgrade. I listen to mostly Alternative Rock, Post-Hardcore, Electronica, and Hip Hop. so i do need wider...
