So, my local hi fi store (Richer Sounds) appears to have a deal on these little gems as they currently retail for £10 in comparison to their normal £50. So, me being me, I picked up a pair to see what they were like. Oh my, actually, their quite good! Now that they've had music played through them constantly for a few days, I'm getting a better picture of them. 
Essentially, they are a universal fit earbud speaker but made out of beech wood in this case. Additionally, they have a tuning port on the back of each speaker as well. They have a 1.2m cord, a gold 3.5mm jack, a small carrying case and a sensitivity of 98dB. Supposedly they have a frequency response of 18hz - 23khz. We shall see...
 
Value: Extremely good value for the price, there is no doubt about it. No, their nothing on a pair of Shures, or Etymotics but they have a certain charm, along with an interesting build too.
 
Audio quality: they can be described as having a "fun" kind of sound with good bass extension, which initially was quite muddy and flappy but since has improved dramatically, providing deep impact but without any woolly stray notes. The mid lows are affected in the same way. Slight emphasis here instead though. The mids are relatively neutral as are the mid highs but the highs are definitely rolled off in places here. For example, cymbals don't quite sparkle (but then, these are reference IEMs, I should stop whining). 
Overall, the sound quality isn't bad at all. There is reasonably good definition, nice impact, a decent soundstage and nice depth too.
 
Design: the design is interesting, one thing being that they are obviously made of wood. Alongside this, as they are supposedly hand turned they are unique. I have noticed this. And it's nice. Differences in the wood grain etc.
Moving onto the cable, they have a woven cable which while can be quite noisy at times does make a lot of difference when it comes to anti tangle. I have yet to tangle them once in stuffing them in my pocket to see if it would happen. Nope, nothing at all. Good times. Plus the little bag is a great bonus too.
 
Comfort: they are surprisingly comfortable and fit very nicely, in my case with the smallest tips, and I can wear them for an extended period of time without any problems. Of course, I can still feel them occasionally and once I got a funny little pain in one part of my ear, but it passed as soon as I took them out for a few minutes and hasn't come back since. With the buds being very pliable, it does help.  Additionally, they isolate passively extremely well too.
 
Overall: a fun little earphone with an interesting design, maybe not quite living up to the statement of "pure high notes" as described, but granted, they are low-mid range at full RRP. Anyway, yes, a nice IEM with a decent sound and fit which can be driven off practically anything (my modded BT928 as of right now) and are an ABSOLUTE STEAL at £10 from Richer Sounds. At full RRP, there is more to be desired in the mid highs and highs, and maybe something should be done about the "noise" from the cable knocking against itself too. The 3.5mm jack looks a tad flimsy as well? Maybe a little plastic sheath or something? 

So I was lucky enough to get these very cheap from Play.com. They seem to be on there a lot of the time at around the £55 mark, compared to their RRP of £160, this is a real steal personally. I think that is something like around $85-90? Again, compared to what is probably a couple of hundred dollars upwards brand new. It might be different across the pond.
First impressions:
Well packaged and protected. Inside you also have the hardcase which is a great bonus due to the velcro pouch inside for storing accessories and cables etc.
First impressions of the audio were also good, even before they were broken in at all as well. Personally, the sound is definitely more muddy without using the NC system, but once you turn it on it sharpens up considerably.
 
Audio quality: I am quite impressed by the audio quality of these headphones for the price. Although the mids can be a tad muddy and the bass doesn't always shine through, the quality is still very good. The main advantage is that they don't need much power to drive them, so you can achieve decent sound quality from most sources, although obviously you get more kick and punch from an actual amp. I did compare them to other noise cancelling headphones, namely the Bose QCs as my friend got conned into buying a set. I would definitely take the Goldrings over the Bose in this case. I also had the audacity to try out some NC Monster Beats as they were on show in HMV. I nearly cried at them. They didn't come close, considering price they were asking for them. So yeah, definitely a good level of audio quality over all, but definitely keep NC on all the time.
 
Design: the design is pretty standard stuff, solid headband, swivelling over ear cups, single sided cable on the left (the cable is also detachable which is great if you can find one with a small enough jack as you can then extend it without needing extension cables). I do find them very comfortable as I like my travel headphones to grip quite hard (in comparison to my K701s which are blatantly my hi fi HPs). The leatherette ear pads are very comfortable in my opinion as is the leather covered headband which feels sturdy and firmly reassuring but doesn't grip your skull in a pincer grip. This combination does make them good for bumpy car and bus trips as they don't take off when the going gets tough. Obviously there are occasional creaks for the swivel cups but the main reason I marked down the design is the plastic does feel a bit tacky and cheap in some ways, finished in a slightly shiny finish although the matt black on the cups is a nice tough in contrast to the blue LED. I have had one small piece of plastic come away from the headphone too, but that was nothing a dab of super glue couldn't fix.
 
Comfort: I more or less covered comfort in the design. They are comfortable, not a word of a lie, but they can get a bit too tight over the head after a very long time wearing them, like maybe a few hours, but then how often do most people have headphones on for upwards of 3 hours without a single readjustment?
 
Noise cancellation: the NC is truly great. I think it's rated at -20dB but don't take my word for it. However, it is very effective. Headphones greatest bane is sub sonic and low bass rumble in the real world which can demolish a good deep track. The NC here seems to focus on filtering out unwanted bass but does a great job of it. Obviously, it isn't dead silent, but for example, a noisy bus engine is filtered away to a gentle wash of mid range in the very distance, even when near to said bus. I used to despise NC systems as I found they made music very clinical, but actually, the sound is still very natural, even with the NC. So again, effective NC. One small issue I mentioned in the overview; there is a slight hiss in the left can. I guess this is some minor feedback due to NC system messing with the driver? It really isn't an issue though, unless you are listening to a) music very quietly or b) music with lulls and quiet sections.
 
Overall: a great entry level NC headphone at a truly affordable price if you can get for it sub £60 like on Play.com. They are reasonably sturdy, quite well made, but they do shine when it comes to compatible and very good sound quality even from (dare I say it) an iPod, obviously within reason of the mp3 quality. Also, the NC is very effective I personally feel, it does a great job of filtering an incredible percentage of noise on say a busy high street. Definitely worth the amount paid for them.
