Both ear-pads are replaceable, and both ear-cups have a rounded shape rather than an oval.
Both have a 3.5mm to 1/4″ adapter.
Both have the same frequency response of 10Hz – 30kHz.
Both have that AKG K240 studio look alike thing going on. That was the first thing that struck me upon opening the SR850’s. They remind me a lot of the K240’s, although I think they are a bit heavier and seem more durable actually!
Volume. The 850’s are a bit louder overall than the 668B. Also, the 850’s are drier and more analytical/edgy than the 668B. The mid-bass of the 668B is warmer, and the treble is a bit different. The 668B is more natural with a better Timbre. What is Timbre? I would say the 668B does better with genres in the vein of Jazz and Classical, while the 850 does better with more modern stuff. The 850 is very crisp to my ears, and seems to do well with a variety of genres. It’s an extremely balanced and detailed can, with no added emphasis on any particular frequency.
Amp. Because the 850 is a bit louder, it really doesn’t need amplification, while the 668B could benefit from it but doesn’t require it. How to choose a headphone amp!
Mid-range. It’s more forward on the 668B.
Treble. There is a spike around 10kHz on the 850. I did find them to be a tad bright at times, but it’s nothing that will cause you to have to take them off. It’s more of a slight “ess” sensation, as if to say the sound does have the capacity to sound a smidgen artificial at times. I noticed that about 95% of the time the treble sounds very realistic.
Headband. The 668B has that weird winged headband thing that the Audio Technica ATH AD900x has. The Samson has the same hammock style headband, but without the wings. I find it to be very convenient and do not like the winged structure. You can find out why in the 900x review above. 🙂
Ear-pads. Samson’s foam pads are more comfortable than the 668B’s pads.
Detachable cable. The SR850’s do not have a detachable cable, while the 668B’s do. The 668B also comes with a 1mand3m cable, while the 850 only has the single non-detachable cable. The 668B’s have a rather odd presentation as far as the headphone jack. It’s a short cable with a 1/8″ stereo plug that sticks out of the left ear piece. You can then attach one of the provided cables. The 850’s are your traditional outfit.

Which one of these you go for depends on the sound signature that you’re after. They are very alike in a lot of ways, but I much prefer the traditional headband of the 850. While I do appreciate a detachable cable, I don’t find it a deal breaker. Both are great for gaming, but for music think about these things before purchase:
If you listen to more laid back music like Jazz and Classical, and genres that don’t really demand a loudness or excitement, the 668B is the way to go. It’s got more of a forward mid-range, and the treble is a bit less edgy overall with a warmer Timbre. This basically means there’s more of a realistic sense about them, but that’s not to say the 850’s aren’t. They’re just a little more intense. The 668B’s are definitely more of a “chill out” type of headphone. Interested?
If you like a brighter sound overall, and a headphone capable of working with many genres, the 850 is your boy. The ear-pads are more comfortable, and the hammock headband is a nice convenience over the traditional mechanism. I really love the sound of these, and was shocked at just how good they are especially at the price. I have to say these really do compete with headphones costing a lot more. The sound is crisp, alive, and has just the right amount of intense to keep you excited. Interested in learning more?
