I will run some more tests on mine, but It's pretty apparent in nearly every single song that there's more bass coming from the left cup. Maybe this is only an issue on some peoples sets. Who knows, but it IS real. I love the sound of these and if I return it will probably be for another pair...

Yeah that's possible. Maybe we'll be hearing more about it as more impressions of these keep rolling in. For now I am honestly thinking about sending them back and maybe waiting for this issue to be resolved because It's quite annoying.

I have this issue as well with mine. It's subtle but its there. the left side is a tad bit stronger/louder and it can actually be really annoying in a lot of songs. I also thought maybe I was going insane but it looks like others are having the same issue.. I wonder if theres anyway we can fix...

I personally listen to mostly rock and metal and also some edm. With the types of the music you listen to I think you will definitely prefer the 770. The bass on them is far superior to the M50's in my opinion. Bigger soundstage as well. Way more comfortable than M50 also. Maybe not the best for...

X2 is great for this type of music. Just listened to this song and it sounded excellent.

Just wanted to chime in and say I've put roughly 30hours on these now and I love them! Also used them to play through the new Call of Duty game on Xbox One yesterday through a Yamaha receiver and they were fantastic there as well.

Hm I can't help you with that one at all. I got my X2 today and have not had that problem at all, but it could be just the way your ears are perceiving the sound.

I got mine earlier today. Only put a couple hours into them but I think there is plenty of bass. I never heard the X1 so I can't compare but this feels like it has a lot of bass where it needs to be when I tested it on a couple of EDM/Trance tracks. I mostly listen to Rock/Metal though and I'm...

I'm listening to that track with DT770's  (Should have the X2 tomorrow) and I can definitely hear the pop/cracks your're talking about so I would say It's the track and not the X2's.

A few years back when I was shopping for one of my first decent pairs of headphones the M50 and DT770/80 were the two I was looking at. I went down to Guitar Center and test both. But right away I Felt the 770 was SO much better, I don't really even see how its comparable. The 770 sounded much...

How much less bassy would you say these are than the X1? like a rough estimate percentage wise? Is the bass still sufficient for you if your're coming from the X1?

Ahhh I want to try this now. I was thinking I was fine with 2 day shipping and getting them monday. But the more I keep thinking about it, I really hate waiting over the weekend for stuff.

Should be here on 11/3 also. That is with 2 day shipping from Amazon. Probably would get it on Friday if I had chose overnight but that's fine.

For anyone still waiting for Amazon.com (US) to get these in stock they now have an estimated delivery of November 12 - November 19th. Preordered mine yesterday.

So the only pair of headphones I own right now is the Beyer DT770 80ohms version, Been eyeing these for a while though. Would these be a worthwhile upgrade over those? 

Oh I realize that you cant really compare, I was just saying that is all I own right now. I plan to buy a couple more pairs of IEM's eventually, just because I cant help myself lol. For the price these do seem pretty great to me though.

I just got these yesterday, they're the only pair of IEM I own so I have nothing to compare it too (my roommate says the klipsch S4 is better, Yes? No?) except my DT770 and DT880 Full sized phones, These are not as good as those. They seem just OKAY to me, Good bass though, they seem good when...

Well I mostly listen to rock or electronic music, some video game music too. I'm just looking for something new that might be better/different is all. Being that these are open headphones I'll still be going back to my DT770's sometimes when needed. (I sold the 880's to my roommate).   From...

Great review!   Think I am going to get Magni/Modi with a pair of HE 400's 

Okay first of all I only read the first maybe 50 pages of this thread or so.   The only headphones I own are HD280's, DT770/80's and DT880/250's, and a pair of R1 IEM's.   My favorite of those is probably the DT770's to me they are a fun headphone, maybe a little on the bass heavy side...

So I recieved my D1 yesterday and have maybe put about 8 hours or so of listening time into it through the usb, might try the optical at a later time. It does seem to make things a lot clearer then through the laptops standard headphone jack, The bass doesn't seem to be much more prominent...

Well I ended up going with the Audioengine D1 over the Headstreamer for 2 reasons, one because it has a dedicated volume knob which I prefer, and two because you can use it with speakers. I should have it on Wednesday so i'll give some impressions then.

Also I only care about sound quality, portability isn't a factor at all.

Looking at these 3 DAC/Amps for use with Beyer 770 Pros (80ohm). Which would be my best option?
