I agree there, shrinking the chamber won't help anything. I just swapped the cups between the 60 and 60is. The old 60s sound  good with the larger cups, the sound opens up and feels less inside the ear as you'd expect. Better synergy with the venting too.  If only I had some wood...

So. Sitting next to me is a set of  B-stock sr60i 's and a really old set of sr60's. From a whole lot of ABing them i actually prefer the timbre of the old sr60's, it might be the condition of the driver (when I got them the gauze front was yellow and the pads were crumbling to dust) but the...

There are currently either Philips SHL 9560 or Urbanears Plattan for less than £10 on gumtree.  Which one should I gut and tinker with?   Should this be in the DIY section?

Is there a headphone out there that is like the hp100 or 150 though a little warmer? Is the 150 is warmer or fuller than the 100? I'm into a  lively sound with personality and presence without too much bloat or boost. I've never owned an 'analytical' headphone before but i'm strongly...

By way of sound impressions (original model): Less busy songs came out better with the Momentums. In my opinion unaggressive blues  could not be improved upon with these. It felt like there was no unnecessary 'tension' in the sound which complimented the genre perfectly. The slow but broad bass...

I've listened to the 300s and 310s back to back. The 300s sounded a bit louder with the same volume setting and I thought the 310s sounded a little smoother overall - could have been the pads its hard to tell.

I'm looking at either the K545 or Soundmagic HP150 . I'd like a somewhat balanced sound with a fun or engaging edge. The two seem to be directly competitive but I haven't found a back to back comparison as yet. I had a look at the specs and they are so close! this might be helpful to others...

Which out of these or the SoundMagic HP150 would be more engaging and rich? I know they are both somewhat neutral but which is more 'fun' sounding? Thanks in advance :)

Do you think that the HP150 has too much bass for Jazz or alternative? I listen to a fair bit of Louis Armstrong et al.

Thanks for the reply.      Which would you say performs better unamped? Also are the plastic arms that hold the cup onto the HP150 at all flimsy, they look quite thin.

Im in a similar ship but looking for versatility across genre as well. I'm coming from  the Momentum which I felt didn't have the treble quantity or bass speed. Which of K545 and HP150 is smoother and richer?  It was that quality that I liked about the Momentum.

That's really encouraging, thanks.  the frequency response graph goes a bit wild near the high end is that good and clear with not too much roll-off or harshness? I'm not great at reading them.

Ah, I should say these are over-ears and I don't currently own an amp. From what i've read the HP100/150 are better with. K545s more amp optional. Some songs I thought about. First sounds 'mazing with the Senns; the others I'm not so sure. https://www.youtube.com/watch?v=cOLTrrcWE5c   for...

What do you experts think about the HP100/150 against the K545?   I'm with Sennheiser Momentum right now but I'm finding the bass a bit loose and the sound lacking energy and clarity in the highs. So I'm basically looking for more punchiness and vibrancy.     *Listens to Swing, Rock, Jazz...
