The 840 is much more balanced and accurate than the M50. I recommend the Shure over the AT.
ACKKK!! From one of the buying guides here:
"Things to avoid
Nice spam. OP wants proper headphones, not Playskool "My First Overpriced Headphones".
Hey Laser ! big thanks for your helpful answer
My choice's going gradually to the M50.
But now the only thing why I'm still thinking about the WS55 is, like you said, more portable.
Do you think they both have a good sound quality for indie rock ?
I'll go tomorrow try the ATH-M50 and SRH 840, and perhaps WS55.
PS: M50s. s for straight cable?
No worries man!
I think the M-50s would be better suited to dedicated listening, being an over-ear design. They seal quite a bit better than the on-ear WS55s.
I was very impressed by the sound quality of both, with the edge of course doing to the M50s.
And yes, the s is for straight cable (a massively LOOOOOOOOOOOOOONG straight cable!)
Something to possibly check out might be the Philips Uptown. You can try them out at Best Buy as well. I just got them today so haven't really formed an opinion yet, but it's very easy to follow the bass lines in songs without it being overpowering or too exaggerated. Great extension too. I was actually listening to some Arcade Fire earlier :) They are quite nice looking and super comfortable. Here's a review comparing them to the M50s and even the SRH840s slightly (reviewer goes by TSIG here on the forums):
I think his claims on isolation from outside noise are definitely hyperbole, unless maybe you're blasting pop music. Here's a thread with some further discussion about that review as well:
Note: I'm not trying to recommend these headphones, because like I said, I don't have an opinion on them yet. Merely pointing out the possibilities. Plus, I haven't heard the M50s. I've auditioned the SRH840s, but that isn't really saying much at all. By the way, you should be able to audition the M50, SRH840, and AKGs at a Guitar Center or Sam Ash if there's one in your area.
even as a noob myself, i have demoed it in best buy and no i wouldnt recommend it, its older brother for me sounds better but even that i still wont recommend it especially if you are going for a buck for buck headphone.
So like I said, I went to a music store and listened to some 100$+ headphones (ATH M50, SRH 840, Grado SR80, AKG K271 Mk ii, HD 25-1 II, Pionner HDJ 1000, Focal Spirit One, ...)
About the AKG K271, although they're light and sound great, they have neutral and flat sound (the best for studio/pro)
Pionner HDJ 1000 and Spirit One was really bassy. Altough I prefered much more the Focal, they were made for DJs and not for Rock music.
Audio Technica ATH M50 and SRH 840 are definitly excellent headphones with clear high/mids. The M50 is more bassy but not too much like the Sennheiser HD 25-1 II.
The best in isolation is HD 25-1 II, then SRH 840 (a little bit more heavy than M50) and ATH M50.
The sound quality of Grado was fabulous for me, but open headphones won't fit in the bus/street.
Well, after all these reflexions, I still hesitate between 2 headphones... SR840 and M50.
I think I'll go with the ATH M50 (overall, I love the sound quality for rock, raggae (more bass) ), very comfortable and quite light comparing SRH 840.
I realise that even there's lot of headphone reviews, the best headphone is the one which you like.
PS: Thanks for your help @manveru. I just read your message right now so I didn't note the Philips Uptown.
