Like them very very much. There are many reviews here in Head-fi about L1.

In European Country including UK released last month online and in some stores. Bought mine from Philips online store and I think in US you can get it from Apple store. Official release imminent. M1 will be soon after L1 released. 

haha.... buy the cheap one first and then ask the expensive one for birthday.  good luck

I have both but prefer L1 than K550 because of portability, sound signature, design and price. You can check some of my post on    http://www.head-fi.org/t/591929/philips-fidelio-l1-review-and-appreciation-updated   http://www.head-fi.org/t/553944/akg-k550-new   Do a search of each...

In my opinion compared to Fidelio L1. The soundstage of K550 is great but not as good as Fidelio. Vocal voice of K550 is louder and sounds like in front of all the instruments (Vocalist stand very close to you), in the meantime, fidelio vocal voice is somewhere in the middle in line with the...

returned mine last week after testing for few days. Design is great and isolation, but sound is not my type. I can't stand flat music. 

I know there are people asking when is M1 arrive. Well finally the M1 have a release date. In May 2012....... reference below.   The pictures looks better than L1, but i do not like on-ear headphone.   ...

Quote: I am thinking that too, next week i will mod the cable to detachable one. Will post some pics when its done, now burning in progress. 

hi all, i am interested to mod my headphone to detachable cable like the M50's you guys did here. Just wonder which method is better?   1) Solder the wire connected the driver (Replace the original cable without cutting it and reconnect using new cable to the chassis) 2) cut the cable and...

  Hi all,    I am interested in K550 and just wonder does the cable removable? are there enough room for modification to turn it removable cable? If the cable is removable i definitely will purchase it.    I am talking about something like...

WahLaoEh,   I am sorry i do not have Creative so not able to compare it. But there are many reviews here in this thread included my review too i think in page 16. I remember i saw it somewhere online saying their release date is in April. So, just a few more weeks to go.   PBwoy - you...

WaLauEh,   I don't think Singapore and Asia have it yet (Apart from HK). First come out on Gernamy, France and some part of europe, then Apple Store US, then Philips website United Kingdom. I think it will be available around April as its their official release time.   Quote:
