The OKCSC M2 open back (OB) have arrived.
First impressions
Build:
They are eally light and quite comfy. The hinges could use a bit of WD40.
I can feel them clamp a bit, but it seems to be the good sort of clamp that for the most part helps them stay on my noggin.
The isn't much padding on the headband, but given how light they are, it would probably be OK had ther been none.
The foam pads are glued to the back of the lip of the cup (not an issue, helps them stay in place). They also stink like dead ****.
Cable looks rather pretty and seems to be of decent quality. Connectors are labelled with letters L and R accordingly. They pop in with a nice click.
The Y
Sound:
There seems to be a slight imbalance where the right side appears to be louder than the left side, but just a bit. When I have swapped the cables and sides, this seems to have gone away as far as I can tell.
I won't be a good judge of soundstage, as even on the AKG K702, I can barely tell something is coming in from close of afar and the AKGs just sound kind of... weak to me instead, like when speakers are pointed speakers away from me.
Then again, with the Beyerdynamic Custom Studio, I almost flatlined when there had been some unexpected sounds when I was either watching something or playing a game, so I'd say I'm not a completely lost cause.
I would say the M2 OB sounds pretty natural for the most part and clarity is very good.
While I can't judge soundstage well, they sound quite open. I haven't listened to anything where I could test imaging out reasonably well, but initial impressions there are good.
The bass is interesting, because when the song calls for it, it can deliver quite a lot of punch and even some rumble.
At the same time, vocals sound very present and clear, while chimes, guitars, violins sound great when hitting the top notes. Initially, they seemed a brittle at the top end and a bit right overall, but after about 10 minutes, either my brain got used to it or they settled down.
Now they sound a bit U shaped, but mildly so, as all voices can be heard quite clearly and not recessed even when the bass guitar is vying for attention.
The tracks I used to test these with so far:
"Leaving Earth" (Clint Mansell) - There's rumble here and the headphones deliver. Maybe not the best one for testing overall, because I think there's some intentional distortion in the track, but where I could be sure there wasn't supposed to be any, the M2 OB sounded clean. Piano and strings are lovely even when the ominous bass is doing its thing.
"I'm proud of you" (Sam Hulick) - pretty much the same story as before. Where the composition should be gentle, the headphones do a great job there, too.
"Lemon Tree" and "Don't think twice, it's alright" (Peter, Paul and Mary) - Their voices come across splendidly and the guitar accompaniment sound like I think - an accompaniment that's noticeably present, but apparently an accompaniment nonetheless. I'd say that here I can tell there's some distance between the microphone and the guitar, whereas the vocals seem to be almost in my ears. That's as I'd expect it, too.
"Burning love" (Wynonna) - the headphones just rock along.
"Morley: Will you buy a fine dog" (Paul McMahon & Tommie Anderson) - vocal and the lute sound both right
"Fosse vero" (Mina) - There's rumble again and the headphones deliver it even while Mina is singing and both remain clear (well, I'd say her voice is velvety, but clear at the same time).
Everything else I listened to sounded good and I can't really find anything to complain about.
I played a bit of Batman Arkham Asylum, but not any part where imaging and stage could be shown off.
In comparison, the Shure SRH-1840 give a better sense of space, and instrument separation. The M2 OB aren't bad at it at all, though. The sound a bit more lively where the Shure sounds more detaile and perhaps has a better balance. It's kind of like of like the Shure go: "Here's what they wanted you to hear" whereas the M2 OB are more like "Hey there (eyebrow wiggle)". :-D
As you can probably tell if you've read the above, I like these.
