Good sound, easy to drive. These headphones sound as good or better than others available at their price. Specially now that they keep going on sale.

I was expecting to have to buy a dac/amp to drive them but was pleasantly surprised how easy they were to drive.

The bad parts are the headband and the cable.
The cables get tangled easily, they develop kinks due to the stuff braiding, and worst of all they transfer the noise from the cable bumping and rubbing on stuff really easily. The cable is easy to replace. Monorice offers a compatible set cables in a pretty clear copper color.
The worst part is the headband. It is uncomfortable and does not provide very secure support. The headphones are heavy which would be a problem with a more supportive headband. As it is it feels like my leaning forward or turning my head too quickly is going to slide the headphones off my head.

The cups have a curved piece of metal attached to posts that is supposed to screw onto the headband using a nut and bolt. Somehow I always find the bolt loose. It's become a habit for me to hand tighten it before putting them on.

I've seen aftermarket headbands and tutorials to swap the cups to open backs. I'll be keeping them stock but I am glad to see that there are ways to modify and improve them.

Despite their flaw. These are good sounding headphones and a good introduction to higher end headphones.

Perfect, many good Bass, strong, sub bass all goes very low, mids are up and fun, treble is clear but no silibant, I listened Emu Teak and this has better and wide soundstage, Emu has more detail and clarity and pin out also is better despite small soundstage, Always keep my M1060C because the complete sound, also the biggest soundstage make a more relaxing sound, is a fun headphone, even better than Focal Elex. I made a MOD with the color of cups very easy to do.

These things sound GREAT. The clarity is outstanding without being annoyingly bright. Mids are strong and full; I haven't noticed the drop-off some have mentioned. Bass is also strong and clear. The organ in the Canadian Brass' Haleluia Chorus made my ears actually shake. But if you're looking for the thump that some fans of (c)rap want, strap pair of subs on and go for it.

My only minor complaint is like some others: I wish they hadn't stained the wood so dark so that the grain showed up better.

Sound quality is phenomenal for the price, but comfort leaves a lot to be desired. If you have a large head you will need to put extra padding between the head strap and the metal band.

Compared to a much less expensive set of Bluetooth headphones (used as wired) from Monoprice, these definitely sound slightly better. The experience is more like hearing the audio in an open room, vs the somewhat "boxed-in" feel of the less expensive ones. But I admit, to my ears, the difference is very subtle. Some say these are as good as headphones costing 2-3X the price; at $300, they are at the upper bound of what I'd be willing to pay for the slight increase in audio quality. I never would pay $1000 for headphones if this is as good as it gets.

For their weight, they are quite comfortable. I haven't had any problem wearing them for extended periods of time. But they are very heavy. At the same time, they don't actually block ambient noise out as well as I would've thought, given their heft. So, there's room for improvement.

But if you want a really clear sound, that makes you feel like you're in the room with the performer, and your budget can handle the price, these seem to me to be a very good option.

The sound is amazing. The adjustable headband is a massive disappointment. By far the worst I've ever used.

The wires that connect to the phones fall out easily and are do not make good contact, I am skilled working on audio products and will fix that.
I am amazed how good they sound. Would give them 5 stars if they didn't have the problem I mentioned above.

Very warm sounding headphones with phenomenal soundstage (it?s extremely nice wide) and the best bass I?ve heard in a pair of closed back headphones; punchy and tight with a great amount of quantity that isn?t muddy and doesn?t interfere with the mids.

The headphones do need a good amount of juice to drive them though. I?m running a FiiO E10K with mine and the volume knob is maxed with the pc volume being at around 30-40%.

quite enjoying the headphones had to repair the swivel headphone connector.
