First off, thanks to all the recommendations and help, guys. Good news is that a few days ago I ordered the Shure SRH840's. Bad news is that I am going to have to return them. I think they are just a busted set, because at a very comfortable listening volume, the highs are getting distorted.
Anyway, I don't know if I am going to simply get a refund, exchange for a new pair, or get something else. While the weight isn't an issue, the headphones are just huge and bulky. Even the cord that came with them is thick, heavy, and unwieldy. I can use them at my desk, but I can't use them around my house because of how cumbersome they are. Also, I'm concerned that there are wires exposed on the outside of the ear pieces that run up the side of the headband; I feel that no matter the care I give these, if I ever travel with them, they might break.
I do like their sound (minus the distorted highs on this busted pair), but I wish the soundstage was better.
I mentioned originally that I wanted a nice pair in the 150 range (I could be persuaded to go up to 200). I still don't want something that artificially enhances the bass, and I don't want something that requires an amp.
Is there anything that sounds like the SRH840's that 1: aren't as bulky, making their use around the house uncomfortable; 2: have a better soundstage, 3: preferably still closed.
I understand closed headphones are going to increase the bulk and decrease the soundstage, but I really don't want a lot of leakage from the headphones where everyone around me can listen to what I am listening to. If a pair of opens don't leak too terribly bad, they might work. And if they have a little stronger, or at least a more energetic, bass, that would be alright. Suggestions?
