Hey I've been lurking for a while now and I've decided that I should take the plunge and see what I'm missing.
I'm currently looking for a pair of closed back headphones that will be used from my Ipod classic, phone and PC. The headphones that I have whittled my choices down to are:
Shure SRH840 - £129 - Amazon UK - $194.94 - Concerns about impedance considering I'm not using an amp
V-Moda Crossfade LP2 - £156 - Amazon UK- $235.75
AKG K550 - £149 - Amazon UK - $225.17
Audio-Technica ATH M50 -£133 - Amazon UK - $200.99
I should note that I'll more than likely be purchasing these headphones from Amazon UK. Out of those three which are the best, I'm looking for a pair that have good noise isolation and sound quality. If there are other cans that are around £150 mark on Amazon UK that you think out perform the three I have listed let me know.
I've heard all these but the lp2 (but have heard m100) and I'd rate their sound quality as: K550>SRH840>M50>M100. All have good sound isolation.
So get the K550 unless you want emphasized bass and don't mind slightly smaller soundstage, in which case you should get SRH840 which deliver amazing sq for the price. SRH840 perform very well without amplification (sorry, haven't played with K550 with different amps). If you want serious bass, the latter two will give it to you in spades and still sound great.
