Man, you really aren't giving us much to work with. For $20 I would toss those Koss cans and trade up to Senn 202s. Then you could get a Behringer UCA202 for around $20 if you scope some eBay deals. Then for another $25-30 and you can find a decent Altoids-tin CMOY and you have a damn good...

Superlux 661 or Samson SR 850 is definitely your best bang/buck headphone under $50. The only gripe you might have is that they're not really true DJ headphones (you cant swivel the cups and put the phone on your shoulder). Monoprice 8323 is a really good option at $25. Then there's AKG K81DJ >...

I don't have much confidence in the E7 alone as to gain. If you are using it with E9 you are good but by itself it won't let you crank your sound up to 11 so to speak, the power wasn't satisfying even with 32ohm cans or IEMs. Take a look at E7/E9 then the Audinst MX-1 and even Nuforce uDAC2...

Quote:   Yup. Everybody raves about AD-700s but the bass frankly sucks. 50mm drivers on the Samson gives a very nice punch and not too boomy. Samson is the real deal. 

Don't waste your money on crap. If you are going to use it as a desktop listening can and you game you want big soundstage and good imaging for positional accuracy. And you need bass. Would not recommend really recommend anything Koss except Porta Pros, their bass tends to be crap. Look at the...

Sony MDRs are a reliable choice but boring and flat. V-Modas are good. Sennheiser HD 25 are really fun and probably the most balanced portable closed can you can get and at 32 ohm you definitely don't need an amplifier, and you can drive it from laptops, iPods or Sansa Clips. Regardless of which...

the AiAiAis TMA-1 are good for pop/dance. at that price range you could also look at V-Moda M-80s or or Sennheiser HD 25 (my personal favorite). nuforce uDAC2 DAC/AMP for the laptop and E11 is best bang/buck portable amp for your iPhone (with LOD cable). You could also do E7/E9, but E7 portable...

HD555 very bright

I would wait and get the HD 25. For portability, comfort, durability, all around balanced and quality sound. You could really use those as a portable (perfect for noisy environs/DJing as well) and general-purpose listening headphone for a long time.

Watching old music videos, I just noticed what Towa Tei was wearing in German Bold Italic.       Who says headphones aren't sexy?    

250ohm DT 770 PROs are $174.95 on Amazon  http://www.amazon.com/gp/product/B0006NL5SM/ref=s9_simh_bw_p23_d0_i1?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-8&pf_rd_r=1W4XDXK12ANYT8VR5CQE&pf_rd_t=101&pf_rd_p=1346186082&pf_rd_i=172541

HD 25 is the best overall headphone under $200. But unless portability is a factor, it's not superlative by any sense beyond being the most balanced, or the most consistent. It is comfortable, but I've found it somewhat fatiguing during very long sessions. Bass is punchy, tight and controlled...

I can vouch for the HD 25s, they handle rock and metal with aplomb--punchy tight bass and a very balanced and versatile sound signature. I had Grados and they were competent for rock and metal but a bit fatiguing with harsh highs and underwhelming bass. Also flat pads on many models are VERY...

All I see are Beats and Skullcandy.
