Well, thanks to Nirvana's link that went surprisingly well. That's some noise it makes when you wrench off the originals. I closed my eyes.
First impressions...
Here's something that I rarely hear anyone else pointing out. Headphones are the
only hi-fi component where I would put sound second in my priorities. Think about that. Anyway, onwards...
Comfort - I must confess I never found the originals to be uncomfortable. They were very snug, perhaps cramped but not uncomfortable. However, the XL pads excel at comfort. I really could wear these all day without any problems. I actually find them a lot more comfortable than my AKG Q701's. I would rate the comfort as very similar to my Shure SRH840's, although the V-Moda's feel far more secure on the head. If I was thirty years younger I might be tempted to headbang with these on. Maybe not
Sound - This is where I need to be careful because I think I know what I expect to happen so this part is subject to change. I've read people commenting that the soundstage is bigger and that's what I would expect. It's not though, not to my mind anyway. I think it's the same size but just a little bit more distant. Not deeper either, just ever so slightly further away. This isn't a bad thing though as it does increase my impression of space within the stage. There's definitely better instrument separation here. It's not in the league of my AKG Q701's but I'm willing to bet there's nowhere near the night & day difference between the two sets of headphones that I've become accustomed to. This is a good thing!
I know that when Val and his team were developing these pads it seemed to take an eternity for those who were desperate for their release. If I remember correctly there was mention from Val that it was not as easy as it would seem to us mere mortals. After all, the original sonic signature was achieved using the stock pads and advertised as such, so to then change one component (especially such a significant one) and still retain the original character was always going to be difficult. I think the problem they might have been running up against was standing waves. The deeper the internal sidewall is the more effect standing waves will have. Too deep and the sound basically comes right back at itself and cancels itself out. We would notice this as a lack of focus, or impact. Let's be honest, impact is what the M's do very well. I think the increased sense of space is evidence of this battle they had with internal reflections. I also think they've succeeded in retaining the overall character of the V-Moda brand sound whilst at the same time making them considerably more comfortable.
I find that there's more treble and to my ears this is a fact. I use Neutron as my player (why wouldn't i?) and with the M-100's I've had to dial in a slight lift in treble since day one. I'm 49 and do suffer from very slight hearing loss on the upper registers, I've been tested. Half-way through my first track with the XL's - "It's Only Natural" by Crowded House from the album "Woodface" (superb recording) - I turned the EQ off. I'm now ten or so tracks in (from different albums) and the EQ is still off. All through this huge thread I've read people praising the "sparkly" treble. Tyll, in his review on Innerfidelity mentioned it too. It didn't sparkle for me, not without help from an EQ. Now I don't have that problem. This is a good thing.
I'm guessing this slight increase (and it is slight, not night & day) in treble is also down to the internal reflections I think I noticed in the spatial differences between the stock pads and the XL's.
Style - By far the least important factor for me but still important. After all, the V-Moda is a very stylish headphone and in matt black it has a stealthy quality to it that you wouldn't want to destroy with big clumsy looking pads. Thankfully this has been avoided. They're only marginally bigger after all and in use, other than the obvious increase in comfort, you'd never know anything had changed.
Summation - I think Val & V-Moda have done an exceptional job here. Considering the stock pads were never initially designed to be interchangeable it's impressive it's possible at all. I do think when the eventual successor to the M-100 is released that we'll see evidence of this enforced learning curve for V-Moda in the ear pads. One would hope so anyway. The company certainly deserves all the success it receives. It's not often you get to talk with the "Big Man" in a company. Not without an appointment and a cheque book anyway. Kudos.
Addendum - I ordered these pads a fortnight ago (roughly). I'm in Scotland, V-Moda are in the far away side of the USA. At the same time I ordered two CD's from Amazon, whose distribution centre I can drive to in under an hour. Everything arrived today. That is service!
The above is only my opinion. The sonic description is very personal - as I point out in the body of the above text I am 49 and suffer from slight hearing loss at the very top end. As ever YMMV.
Peace out.
