5. Fit
5.1 Clamp
The second least in my list. Denons have the least followed by these. Or is it.......
[size=10pt]Q2. These are way too loose for my head. Only for big heads is it?[/size]
The following paragraph may be the most important thing for you in this entire review, so please read it carefully:
Out of all of these headphones, the k550 is very unique in one aspect. The clamp is adjustable. Yes, I'll say that again. Without any mods at all, the completely new out of the box akg k550 allows, by design, for us to adjust the clamping force the headphone exerts on our heads.
How and why?
This is simple. You see the actual earcups can be moved in both the up/down and right/left directions (read below) BUT each 'change' you make to the inclination of the pads require application of actual force- using your hands. This is especially true for the up/down movement. Unlike other headphones where the cups are attached to a loose swivel hinges, these won't change shape once on your head as the force required to make this change, to make the earcups move, is far greater than the outward (normal) force that your head can provide- so there is no movement.
All this is largely independant of how you use the headphones left and right size meter (how big your head is!). 3 clicks on either side or 5, you can still change the clamp of the headphone by moving the earcups.
Importance?
Getting a good tight fit is crucial for good sound. When I first got these I thought they sounded awful. I had them ready to send back to amazon. The next day however, I couldn't believe my eyes when the earpads moved up and down after I pushed them. THEN I had the fit. THEN I realised what headphones these are. Gone were the tinny mids and highs, the bass deficiency and the grating highs. A few experienced headfiers I suspect haven't really played with the fit- as their final impression of the k550 is exactly what I thought of it when I first tried it out.
Look at my profile and see the closed headphones I've owned. I'm not embarressed to say that I got fooled at first with the k550, as it's just so unique in this regard. You know what- I doubt that there is another full size headphone that functions like this...
