drop had hd8xx for as low as $1099 with $200 credit (or even less), yet hd800 always sells well at $1150

In the case of 800s/8xx, yes. They made tuning changes. For 6xx they did not. 650 has the advantage of a better build and Sennheiser warranty.

6xx and 650 are identical drivers, but the 6xx just use the old plastic mold (rounder edges) and have a dark blue matte paint. The 6xx also come with a shorter cable than the Sennheiser branded 650s.

I have had the 6xx for years have been craving "the original" colorway with Sennheiser branding. I hopped on this deal even though they sound the exact same lol. More of a collector's mindset, but if anyone wants the save the cash the 6xx is absolutely the better buy, and even comes with more premium packaging.

No, but they do better with one. I don't listen to loud music but a dedicated amp allows me to have more possible volume range from them.

To bring out the best of the 650, you should.

I have the 6xx's. That cable doesn't need to be any longer lmao.

The only reason I could think of for a longer cable is if you were plugging in to a stack from halfway across your room.

I'll say this too, I've never actually held a Laird of 650's in person, but I can compare the 6xx's to Philips Fidelio L1's and X2HRs. the build quality on the Sennheisers is a definitely a step down compared to those two. premium metal and leather vs plastic.

BUT, the build quality on 6xx's are fine. I don't see where they'd fail unless you just squashed them with your butt or they take a super awkward fall on tile/concrete

For those that care about this at all, the newer ones do not come with the headphone storage box. You just get the headphones in cardboard box.

Even the MassDrop HD6xx I got came with the storage box.

The HD6xx materials are good enough. But if you absolutely must have the Sennheiser HD650, don't care about no storage box, and willing to pay about $90 more, then this is a good deal.

Have a look at something like SMSL SH-9.

Do you notice much difference in the material quality between the two?

I don't have this but it's well regarded for the money: Fosi Audio K5 Pro (About $70)

I like my TOPPING DX3 Pro+ (currently $175 on Amazon, which is a good price for it).

I mainly poked around https://www.audiosciencereview.com/ and found what I thought was a good balance between performance and price.

I like the HD 650 (I use the Drop version, which are less expensive but sound the same) but haven't tried the 660s.

I'm curious if the 300ohm impedance in the 650s or 6xx's would be too high for a fender mustang micro amp to drive for apartment guitar practice. I currently use M50x which Reddit likes to dunk on but the low impedance seems to be feature in this use case
