Good luck on trying to change out the earpads from the fake leather ones installed, to the velour pads included. First, there are no instructions on how to remove the pads. Second, it is nearly impossible to install the new velour pads given how the pads attach to the phones. In trying to install the pads, you have to fit a flexible piece of coated fabric into a groove, while manually stretching the pads to cover the location on the earphone. In trying to do this, a coating on the phlange of the velour pads peeled off. I finally gave up on trying to install the velour pads and spent an hour trying to get the original pads reinstalled. On the other hand, I picked up these cans for only $330.00 with the big25 discount. I'd also say that the cans do a poor job at isolating outside noise. Equivalent to Audeze LCD-2 closed backs? Maybe.

Background:
I was looking for a solid pair of planar headphones for awhile and found these which looked perfect. I picked them up on sale and discount for a great deal.

Opinion:
They've absolutely knocked it out of the park in sound and build quality, so they're becoming a mainstay in my collection. I'd certainly recommend these to anyone on sale so long as you have the equipment to drive them (they're fairly beefy). The Velour pads they come with are definitely my preference in terms of comfort.

Pros:
Fantastic Sound
- Well defined sound, signature of Planar Magnetics
- Decent Bass even for planars, but could be tuned with EQ
Build Quality
Earpad Variety, coming with both leather and velour
Solid cables
Hardshell case for transport

I don't have really anything negative to say about these, however be aware of:

Size: Huge headphones, biggest I've ever held personally)
Weight: I don't have the exact weight, but due to the materials it's no surprise but they are HEAVY for a pair of headphones but they're built well. You definitely get your moneys worth in that regard.

Don't judge the headphones until you try the velour pads vs the pleather. I was actually about to return the headphones when I saw a suggestion to switch to the velour pads online. The velour pads are physically warmer, they don't look as nice - but once I changed to them the sound improve tremendously. I stopped trying to equalize out issues with the pleather pads.

First closed-back headphones. Not sure how much noise isolation they're supposed to give, but the M1570 is not impressive in this regard.

It's really heavy. Not recommended for glasses wearers, but that might go for over ear headphones in general. The weight transfers to your glasses, pressing down into your nose bridge.

Sound is V-shaped, though I still put a 10db bass shelf on it. I recommend EQ, but I EQ everything I have, so there's that.

I wouldn't purchase this at 600 USD. But when it's on a good discount, and if you don't have a closed-back planar? It's not a bad choice.

Really good headphones. Bass, soundstage, and highs are top notch. Vocals are a bit recessed. Overall im really enjoying these headphones.

So far pretty good . Haven't had too much time to go through my library but what I'm hearing is a pleasant surprise . I got my headphone amp about the same time as the cans and that helped the sound quality some . Waiting on the dac now to finish the set and to make a final opinion after listening for a couple weeks . These are the first planar cans for me and I never spent more than $300 on headphones like wireless sennhieser and V- Moda . The pads on these are a good 4in across and they are big but , they are comfortable .

Excellent headphones, brilliant quality, clarity and and precision.

Sound awesome

There's a lot I like:

- sound is good. I'm not going to waffle on about the large soundscape or whatever, but I really like this for my music. I never miss anything. On the contrary, I sometimes hear things that I don't hear on my speakers. It certainly sounds better than previous headphones, like a Sennheiser HD-580, HD-599 and an Oppo PM3. On this basis alone, I give it 5 stars.
- it has a certain heft to it
- my ears fit
- the price, especially when it's on offer < US$ 400, is excellent

There are some things I don't like:

- the plugs from the cables are long enough to often touch my collar/hood
- all my sources have 3.5 mm plugs, and the adapter in the package is very long, which makes using it risky. So I had to order an AliExpress cable
- I'm not sure how monoprice US and monoprice EU are related, but I can't fathom why it's only sold in the US. Shipping was painless.

Pretty incredible headphones for the price. I'd expect a little less creaking from the headband given the price, but the drivers sound wonderful and despite its weight, it's a very comfortable pair of headphones.
