I've been sleeping with IEMs for years with the same pair, and had 0 issues. To my ears, they aren't muffled at all. But I'm also using the blue filters with the foam removed - from what I read, that's the best way to listen to them.

I just got a pair of the SE846 the other day, and I'm enjoying them quite a lot. I also tend to enjoy BA sound though, so... One thing that's a big deal to me is being able to sleep in IEMs, and that's why I don't currently have a pair of customs. They tend to be a little too bulky to sleep in...

What are you comparing to when you say that? I have to say that, like most of the other posts so far on this thread, really the only way that IEM's are lacking is in sound stage and the physicality of the bass. Other than that, I'd say that for the money, the right IEM will produce better sound.

Lucky! I've been thinking about ordering them since I saw them on the RHA website about a month or so ago. How were they? Have you posted impressions anywhere?

Well, I just bought the A2e today. I'm excited to try them out. I had an A6 for a while before, but decided I didn't like it that much, because they didn't really make anything sound too special. Hopefully these will sound special with something. If I don't like them for general listening, I'll...

that is the Adel module :) they're removable so that you can exchange them for the adjustable ones and different variants on the Adel modules, as they become available. Also, for instance, my a6 initially came with a broken Adel module. 1964 was able to send me just the module, instead of having...

    I... Yeah... I meant that V series. I'll go edit that now... Thanks for pointing that out!

That's correct. Those plugs are for the V series, and their attenuated ear plugs. Not for the Adel series, unfortunately...

They're fairly low profile. I don't think you'll have any issues with wearing things over the top of them. I personally can't side sleep in mine, but mine are the A6 with twice as many drivers. I would think that the A3 will probably be low profile enough to allow side-sleeping.

I got the a6, because it was all I could afford at the time... Also, I was looking for something with less bass than the D7k,which is exactly what I got, so I'm actually really quite pleased with them :)

Well, I personally am a fan of pretty much the same stuff. I had the Denon D7000, so that's a common ground that we have, although I can't say that I've ever tried any of the other headphones that you have.    Anyway, I find that the A6 has more than enough impact for my taste, although the...

Thanks everyone for the kind words, I'll see what I can do about making something a bit more thorough for people's reading, since I feel that my write up, up there didn't really capture everything.   Quote: Well, the A12 certainly has a darker presentation than the A6. The A6 is a nicely...

    heh... I went from my bed watching videos to the kitchen table to type this... This may take a while.    Anyway, All transducer types have their own advantages and weaknesses. Since we are talking about IEMs, I will try to keep it in that realm, but I suppose I'll give a broad...
