Superlux HD-651 White

I needed closed headphones to record vocals. My monitor headphones are open type and the sound always got into the recording, so I decided to buy these headphones.

In terms of sound quality, they, of course, are many times inferior to my monitor ones, but they were not bought for these purposes.

The headphones are comfortable, do not press, sit comfortably on the head.

There are practically no sounds on the record.

Made of cheap plastic, but it feels like it NEVER breaks.

To summarize, I can say that these are excellent headphones, but not for listening to music, let alone monitoring.

I bought three pairs of these to give musicians when I'm simultaneously tracking a whole band or rhythm section in my little drum room.

I expected to only hear mids, but when I tried these little "toys" I was floored!
Firtsly, deep, DEEP low end! Not overwhelming, but present, great for bass players!
The low mids are obviously a bit colored but not much worse than my AKG K-182s, but they are clear and are very pleasing for electric guitars!
The high end is soft and quite linear considering the price, these are not hi-mid or treble-forward headphones, so they are not fatiguing to the ear.
Also the isolation is nice and linear in the high-end and the ear cup material seems quite stiff and durable, unlike AKG and Mackie ones I've tried.

The only thing I don't like is that they are small, I've got a big head and they do fit but barely, I'd like them to have been more adjustable, but for the price I'm glad they have very few moving parts.

Conclusion:
They are fantastic for tracking if the musicians don't have huge heads, for me these are better tracking headphones than my Beyer DT-770s, they focus on the important frequencies for hearing instruments and proximity effect when tracking vocals, no one needs piercing high-end when tracking.

I'll definitely buy more.
