I use it at home. so it does not require portable, but does not want it too bulky.:smile_phones:

hi guys, I am looking to buy USB DAC/ amplifier for watching TV/ movies on my desktop/ laptop. Headphone: AKG K701, Sennheiser hd 650 Budget: < 200 USD what do you guys think of (other devices are highly welcomed.) 1. Fiio E10k 2. Schiit stack. (Magni + Modi 2)

Your mp3 is not powerful enough to drive most big cans like Sennheiser HD650, AKG K701. If u prepare to upgrade your music source into DAC or CDP, u should choose AKG K701. It is a little higher than $200.

Wireless?! never consider for hi-fi. 

Own HD650 and love it also even thought it is a little tight for wearing.

Grado sr60i sounds good and is easy to drive by computer or any portable device. But Grado is not so comfortable to wear. 

It is true that computer cause jitter because computer is not designed for hi-fi audio. Computer is for calculation and computation. 

Please add Grado sr60i into your consideration. It is really good for movie and pop music.

It is not useful to convert a loss format mp3 into lossless format FLAC.

really nice price although I never got a chance to hear the sound.

shure se535, grado gr8/10.

beyerdynamic dtx10 is a option for you. check it out.

I just owned TF10 also from Black Friday in Amazon. Still burn in TF10. I heard shure se530 has more warm sound than TF10.

My percentage status is: Headphones...........25% Amplifiers...............25% Source...................30% Cables/accessories.20%

Add Grado into your consideration especially you like rock.

Grado sr60i is great! but is a little higher than 50$, which is 79$, but worth every penny.

Grado sr60i is the best in this price range.

AKG K701, Sennheiser HD650 are good options. 701 is a little mild comparing to HD650, but more comfortable and easy to hearing. HD650 has strong bass. Pick the one u favor.
