Only a 4 because my first pair suffered a driver failure. Customer service got on the ball and replaced my unit. I love these headphones. I don't hear the peaks in measurements that have been posted online. They have glean bass and just enough treble that I'm not quickly fatigued while listening. Metal, EDM, classical, alt rock and classic rock are all handled pretty well.

These sound pretty good. I purchased these (on ebay via the Monoprice store during a sale they were having) because I recently started a job with an open floor plan, so I couldn't use my Hifiman open headphones. The soundstage on these isn't as wide (I haven't compared them with other closed phones), but overall the sound quality is excellent. Good bass without being boomy. Even though they're heavy, I'm, able to wear them for several hours a day without discomfort (and I have fairly large ears). They don't make my ears perspire like some other sealed phones do.

Now the complaints:
1. The headband is very flimsy. It's not to the point of it falling apart, but whenever I take these off my head, it twists, causing the two earpieces to hit one another. I suspect that after a while of this they'll start to show scratches.
2. Movement of the cord against anything (such as your shirt) is audible. Typically my music drowns it out, but it's sometimes noticeable.
3. One of the screws holding one earpiece bail to the headband loosened up after only a short time (I posted a query about this but Monoprice didn't respond to it, even though a couple of other users did). To fix it I had to remove the four screws holding on the wood back piece, then I was able to use a short screwdriver to tighten. If your earpiece is scraping against a screw, this is likely the problem.
4. Yes, they're very heavy, but this is part of the price we pay for planars. You are always aware that you're wearing them. Having said that, they personally don't give me a headache, but I can see how they would for some people.
5,. Not truly closed While my coworkers can't hear my music, the sounds around me are pretty audible. I don't really consider this a bad thing, since I want to know what's going on around me.

Very good sounds for vocals. Better than hifiman he560. Nothing can match these cans at this price.

Unfortunately, my headphones arrived with one side not working. I’m currently waiting for a replacement. Maybe I can update my review with a better experience but the return/replace process is very very slow..

It exceeded my expectation in terms of clarity. I still love my Isines. But this is something else...

Great Head Set at an Affordable Mono Price Pretty Good in Stereo Too!

It's an amazing sounding set of headphones. The soundscape, while more focused than the open backed m1060, is just as pleasant, especially for music with many parts. They aren't very good moving around since they are a bit heavy and bulky, but it's worth it for the listening.

The headphones and case have an extremely strong chemical smell. I set them next to a window for a week to air out, but they still stink.

I can't wear them without my eyes watering from the smell. I will be returning them shortly.

They just get better with time, slightly heavy, but definitely do-able, perfect match for a Schitt Lyr 2 with the Bifrost multi, they handle 6 watts no problem, they need break in time, little flimsy with ear cups, but overall you'll love them in time, sound quality is there, sometimes a little shallow on the highs but good

These are great headphones. The sound is balanced and clear across the audio spectrum. The bass sounds like punchy and clear; the mid-range is clear and precise and the highs are clearer than I have heard in any other headphones.Not only do these have great sound but they look very class with the wood ear-cups. I would definitely recommend these to anyone in the market for new headphones!
