I have no idea... Since you use imgur perhaps you should try posting it to reddit.com/r/headphones you can view images from there at imgur.com/r/headphones    Or you could ask your girlfriend, or her parents, or her grandparents

Well firstly the over ear headphones are supposed to go around your ears, so if the UE6000s are pressing on your lower earlobes, causing discomfort and you intend to use them for long periods of time in one sitting, I would recommend selling them and getting a pair of headphones that has...

Yurbuds makes quite comfortable sports earphones, at a low cost. I have used their Inspire Series of earphones (although I dont quite remember which model). http://yurbuds.com/products/in-the-ear/inspire/ At $30 you cant really go wrong. SQ is nothing spectacular, but at least I recall it...

When you say workout when exactly are you going to use them? Do you mean like going to the gym, or for rock climbing and cycling, or for light jogging, or marathon running? Perhaps you should try searching for reviews from people who use the Westones for the same purpose as you do, different...

  That is a good suggestion, but I have yet to order the E10. As for the amp I only have 1 qualm with the O2. Is the O2 amp going to sound too harsh when used with the Beyer DT880 600ohm? I intend to get those cans as a sidegrade in the future but cant audition the O2 amp with headphones I dont...

Thanks for all the suggestions! Now first things first, I have the HD 600s on my head right now and listening to it right now I would say that it most definitely does not sound bad. In the audio store, I listened to their setup Mac > iFi iUSB > iFi iDAC > iFi iCan > HD 600. Comparatively...

In that case I should purchase the DAC first. Just a quick question, how would the lack of sufficient amplification affect the SQ of my cans? Would the reduction in SQ (as compared to a properly amped headphone) be very drastic? The Fiio E10 also includes an amp, so it would cushion the impact...

For my DAC I would also be considering the Fiio E10

My budget is $150 USD

So I will be getting a pair of Sennheiser HD 600s tomorrow, but only have enough money to get the cans and either an amp or a DAC. My audio source would be my 5 year old laptop, and a minor concession would be a small portable amplifier in my possession, a Fiio E6. It claims to be able to drive...

Does anyone know how the Vali sounds when paired with a HD 600? It seems as though the Vali does not have much synergy with the HD 650...

I would be using PC audio solely for music. As for the Hifimediy Sabre U2 USB DAC, it is not sold in my country, and does not ship here on eBay either. In fact even DACs like the Schiit Modi cannot be found in local stores. Thankfully headphone availability is not an issue and speaking of which...

  A portable headphone is usually made to be lightweight, built for more rugged use, of low impedance such that it can be powered from a DAP or mobile phone. Something you would feel comfortable wearing and walking on the street or on public transport.   A non-portable headphone, for home...

  True, although my intention was to let OP try a cost-free alternative solution first before making a purchase. If it works out, then good. If it doesn't, well, no harm done.

Alternatively, a cheaper solution would be to use an equalizer for your music. Not sure if iPhone 4s has that feature though. Being a former basshead and owner of a pair of XB500s, I can understand why some may not be content with its bass.
