It's true.   The early 681's had bright red accents and the highs were very piercing.   The later ones had maroon colored accents and the highs were smoother but still pretty bright.   There was a third one, which was also maroon colored, and even less bright, but still bright.

Wanted to buy some black earpads for these from Amazon since mine are turning green.   Are the black Velour pads thicker and softer than the ones on the 770-Pro-80? Someone told me the ones on the Pro 80 are a bit thinner and firmer than the other DT's

I'm looking for a complete opposite of the DT-770 Pro 80ohm. Thinking about the AD-500x

I just installed my Xonar DG again for my DT-770 Pro 80's Sound quality is pretty much the same as onboard but I needed the amp because they were too quiet sometimes.   I also need to replace the earpads, mine are getting gross and falling apart after a lot of cleanings.

The Pro 80 and 250 is known to have boomy bass when amplified poorly.   The 250ohm version has a tighter clamp, and slightly less bass with perhaps a bit more fidelity in the mids and highs. It's a very small difference though and not worth owning both headphones. 

I wouldn't get an amp for the 681's or any of the lower tier Superlux's unless you plan to upgrade in the future. 

Quote: That's very possible, but which 662?    I'm kind of regretting getting my DT770's because I want to try these :P

Apparently, there is a new version called the SR950.       http://www.amazon.com/Samson-SR950-Professional-Reference-Headphones/dp/B00CBPJLFW for $71 USD ATM   It looks like it's fully closed and not semi-open like the SR850's.  It also comes with velvet pads instead of Pleather...

I've heard good things about the xb400 which I see on that website.   They aren't truly audiophile quality but for casual listening they're fun and comfortable and I feel you would like them a lot especially considering your music :)

681 if you want something more fun sounding with a wow factor. 668b if you need something more neutral and less colored with smoother highs.   I would highly recommending replacing the pads on both, the stock are horrid.

I don't feel these need an amp unless you have very very picky/sensitive hearing, they will sound fine out of your onboard sound 95% of the time.   A good cheap soundcard I would recommend is the Xonar DG. It's a noticeable step up from Onboard for not much,

Please close the thread.   Thank you for all your suggestions, but I posted this quite awhile ago originally and now I am content with my DT770 Pro/80s

Quote: It's a whole different league of headphones.   The 80ohm version does need a cheap amp to sound its best, but even without it's much better then the Superlux. And you don't need to get anything fancy to amp it so you could easily get one in the future.   IDK of any other...

Quote: the evo and old 681 are the same size so they should fit.

Quote: You should save up $40 more for the DT770 Pro/80. It has a very similar sound signature to the 681 and is super comfy and a deeper soundstage

Quote: when you see someone say "basshead" on head fi it usually just means "a more bass than a neutral headphone". The same thing happened with my DT770 Pro/80s. Though its a bit different since they actually do have a lot of sub-bass but not much mid bass punch.

Quote: The third generation 681's (maroon red) actually have toned down the treble a lot since the original 681 (bright red). At least according to audiohipster. But maybe more so with the new 681.

Quote: it's just more flimsy, cheaper plastic. The headband on mine broke (the ear cup broke off) and I had to tape it. 

Quote: I think slightly thicker, the material is also more comfy too.   HD-330 with DT770 pads must be god like because I have the DT770 Pro and its pads are perfect     I think the difference between the old 681 and new 681 are small enough you should get the old 681 with AKG 240...

Quote: Very similar sounding. I believe the Pannies have the same driver as the HARX700 too.   The JVC's have much better build quality which is the downside of the Pannies. And more isolation. The pannies have a wider soundstage and a more airy-open feel to them.

Quote: I'm pretty sure they are the same.   Usually when a headphone has an -S at the end it means it has a straight cable, but I don't think the htf600 has any other versions

Quote: This is true for me. I have a slight rattle in the right speaker occasionally when there is a lower bass tone. It's bearable, though. I had it from day one.   The DT770's are built like fricken' tanks. I haven't owned it for very long but they are built very very very well and I...

Quote: Welcome to Head-Fi!.   Be careful trying to mod them because those internal wires are delicate. That's how I broke them (don't worry, it was user error). I recently bought some DT770 Pro/80's to replace them.

Quote: Ebay. I think you have to ask for black though. Audiophipster sells them.
