A condensed reply, at least for now
If you want more info, just let me know
I liked the HP100's very much, except the bass where to me
they lacked sufficient depth and impact. But nice soundstage,
very good detail, and a clean, clear sound that was very
attractive. If the bass was tuned differently, I certainly would
have kept them.
(no, I am not a basshead...)
The K550's sounded odd somehow - something weird with the
sound signature that's not easy for me to articulate.
When they sealed well, and were placed "just so", they sounded OK
although rather thin throughout the range.
But getting a good seal was a tricky thing to do. I noticed in
the relevant threads at the time I owned them that many others
commented on the fit issue as well.
Good soundstage though for closed headphones.
Pretty comfortable, too.
BTW - yes,, the 840's are heavy clunkers no doubt.
Still, though, as I posted above, I think they are quite
good closed headphones soundwise in their price range.
The set I had was well padded and pretty comfortable
despite the weight. That was more than a year ago -
wondering if they're less padded now? Anyway, if
you can't wear them because they're too uncomfortable,
that's that for that - they've got to go. It's very rare for
headphones to become more comfortable over time
So, I think you're best looking away from these three.
I recommend that you try the new NAD HP50's, which
I like very much despite their strange appearance.
Excellent sound and good comfort (though, of course,
others disagree on that - you can take a look at their
main thread here:
Another closed headphone I like: the Yamaha MT220's.
Not getting a lot of mention but very solid value IMO.
And then there are the very, very good Sony MDR-7520's
More expensive than the others mentioned here but well worth it IMO.
Finally, a couple I'm looking forward to hearing as they're getting
some very fine reviews here on Head-Fi and elsewhere:
The new Focal Spirit Pro, which at $349. seems to be
a great deal, and the AKG 545.
After listening to the 840's last night I realized just how bad my K240's sound.
So now my priorities have changed.
I'm looking for the BEST headphone that is as HONEST as possible in the $300 $350 range. (open or closed)
If I buy an opened headphone I'll just get a cheap $40.00 closed headphone for recording.
I'm going to audition the NAD tomorrow along with a PSB M4U 1's (many sites consider it to be the best HP for $300.00)
I'll audition the Focal's when they come in in a few days but now that my budget has increased...what about the MAD DOGS?
There's a lot of love for them here and they ARE professional recording Fostex's.
