The K545 simply are to new to have lots of reviews. I am confident they will have a huge customer base over time. I like the last few posts, they all give good information, pay particular attention to shinbones comments about the Q701 being used straight from a portable player IT'S IMPORTANT!
AKG new headphone K545? - Page 34
Gear mentioned in this thread:
I find it worrying though that the glue becomes softer with time, so with excessive use would they stop working.
How long would these last because I don't plan on replacing them any time soon.
I think you reading to much into his theory of driver burnin. While no one knows for sure how long this headphone will last in daily use (it's only a couple months old after all), I highly doubt it will fail easily. AKG has been making headphones for a long time and their products generally last for years and years.
Lukalop, I didn't mean to suggest the glue may fail soon.
For one, "glue getting softer" is just my guess. It is a common theory with guitar amplifier speakers, and that is why I mentioned it. There are a tons of vintage speakers (both hi-fi and guitar amps) still in service. Like anything with moving parts, components wear and loosen / soften with use. It is nothing out of ordinary. Once guitar amp speakers settle (once the glue gets softer from its initial stiffness), they are good for years and years of use, often under less than ideal conditions (gigs on hot days, cold nights, high humidity, accidental beer spillage, storage in non-air conditioned places, etc., etc).
And two: there are a lot of people who do not believe speakers change sound as they are used. I am pretty sure some people who read my post would argue I am only imagining it. You'll have to see for yourself.
K545 is very solid. Its build quality is very good. The way the cups stay where you put them is very assuring -- a lot of headphones do not do this. I am pretty sure they are very durable and reliable.
I think the question you should ask yourself is where you are going to use the headphones, and with what source.

UPS tracking page keeps lying ... hopefully I'll get the Sony delivered tomorrow.
Beagle, I see you have some headphones I've been considering. How do the K545, NAD HP50, Soundmagic HP100, and Sony MDR-7520 compare? I am specifically interested in on-the-go portable use.

Thanks Beagle, I thought that might be the case. I owned the 7520 very briefly and from memory thought the K545 would be better in those areas but direct A/B comparison is much better than going by memory.
Thats exactly what I was going to say but refrained since I don't have both. The 7520 has a lot going for it but the k545 had a softer smoother sound from what I remember.
Everything you said could be right. I just said smoother. I don't know if more refined is right or not but the 7520 is a sharp sounding headphone. Its not what you would call smooth or soft. It is very balanced and its bass has more detail than any hp I have ever heard(mayby not lcd2)
