Superlux HD-660 Pro 150 Ohms

I previously owned the Superlux HD-660, and I wanted another pair, but they were discontinued. Until I discovered that THESE (the 660 pro) dropped. I ordered immediately to see what they're all about.

These are more of a middle ground for recording/mixing, since they have a tiny bit more bleed.
But the pay-off is big. You can wear these for hours and feel zero irritation. Very soft and cozy feeling on the ear.
They're a tad bit brighter, but they also respond a bit better at the sub-bass frequencies. And also, the original 660s were also giving me a bit too much around the 600-1000hz area, whereas these don't. So, you could say these are a bit more V-Shaped, in comparison.

I enjoy listening to these more, and wearing them for longer hours too. And they're absolutely fine for recording too. The bleed levels are STILL comparable even to the DT-770s.

If you don't wanna spend much and still get a comfortable, great &bright sounding pair of headphones, look no further :)

Based on the looks I guess these are supposed to be some kind of DT-770 clone??? The sound is not even remotely as good. The Beyers have much better detail, depth, soundstage and FAR better low extension but I guess this is to be expected at this price.

I guess they're ok for the money but if you want GOOD headphones you'll have to spend more money.

On the positive side they seem to be reasonably sturdy and the cord is nowhere near as fragile as on certain other Superlux headphones. They also sit comfortably on my head.

They will do the job as tracking headphones in my studio. Cheap and easily replaced when a musicians sits/steps on them.

I received these headphones, I liked the packaging very much, there is a good case inside. The headphones themselves are very light, the ear pads are velor, the bass in the headphones is heard very well, the middle is not very clear, but the frequency response is transmitted correctly. They sit comfortably on the head, you can work in them for a long time. When recording on a condenser microphone, the phonogram is not released outside; they are well suited for recording vocals and singing along with a phonogram. I made a detailed review of them on my youtu.be/XtVKONzrvNg channel. I told everything how they work at home. Of the shortcomings, this is not a very high-quality arc, it has a cheap leatherette, metal fasteners are not polished, you can cut yourself, the wiring is flimsy, but it will go for that kind of money. Thank you Thomann for the good packaging, I am satisfied.

Set I purchased have noticeable distortion on left side which makes them useless. They are very very comfortable and I may take a chance on another set, as they are the most comfortable low cost headphones I've tried, and they do sound very good in the right side.

EDIT: Thomann stand behind their products and sent a replacement. As I hoped, the replacement did not have the issue with the left side.

Pros:
-Very comfortable. More comfortable than Beyerdynamic DT880s which cost 5x more, more comfortable and better sounding than the Tascam TH200 I also have that are in the same price range but 32 ohm and heavier on the bass. The DT880s sound slightly better, but that could be confirmation bias given the price, although they are designed for transparency. I bought the Superlux for tracking, and they are excellent for that purpose.
-very clear and detailed
-well isolated, I'm using these in my basement "studio" and they are quiet for the outside, and sufficiently noise cancelling as well for my purposes
-for casual listening they sound really good on a quality vintage receiver with the loudness (bass boost) engaged at a comfortable listening volume
All round great deal considering the low price.

Cons:
-did have the one with a bad channel. After the replacement set arrived, I took the bad side apart. One connection was held together with shrink tubing but not soldered. I soldered the connecting wire, and that solved the problem. So again, QA was an issue at first. Otherwise a very good sounding headphone at this price point.
