Hello not sure if this is the right thread but my fiio btr5 is completely bricked. I tried resetting it to default using the app and after it turned off it didn't turn on again. I tried entering dfu mode so many times and it wont even do that. I bought it off from aliexpress official fiio...

Oh yes I'm definitely leaning towards that as well. The song was panda by designer. Haven't heard it on any other song so far. I didn't want to return them as I got them for 65$ brand new (apparently). They sound different then anything else I've owned! Very special pair of iems.

Can you tell me what kind of buzzing sound do you notice ? Is it like a grain/static when bass drops during certain frequencies ? I just got mine and I fear it has this issue too :/

Been rocking red backs + pink fronts for more then a month. Havent looked back. http://s.aliexpress.com/Z7vYFNry (from AliExpress Android) Also got this cable. Bass feels less in quantity abit but so much more controlled!

My cable busted as well. How does one go contacting lz? Should I just contact penon?

does anyone know where to buy the foam tips that come with the jvc fx1200s and maybe other woodie series? I really like them but I got the fx1200 used and they seemed to be a bit worn off. The tips also play very well with my lz a4s.

Wow the blueB and GreyF won me over! Such a unique sound. So much details in the mids and the imaging is so sharp (almost binaural effect).   

I'm on the fence choosing between fx750, fx850 or fw03. Anyone who owns the fw03 here? Or any more impressions on them. 

  Yes! This was my exact impressions of the gray fronts. The cymbals in metal for example come organically where as on other filters they're more pronounced from the start.    GrayF+BlackB overall a very pleasant listening experience. 

  Hehe I agree with you that's why I said all the front filters have something going for them in one way or the other. Still I think the grays are a bit underrated. I personally never bothered trying them on until now and they give me the perfect balance as far as vocals and overall smoothness...

The gray fronts dont get enough love imo. They have the perfect balance between the black and green. For me the treble doesn't have the peakiness both those filter had making vocals easier to understand in songs with alot of background instruments. Though I've been flip flopping alot so who...

I dont get why the yellow tips which are included with most lz models aren't included with the a4s. They work alot better then most of the stock tips included.

Using my samsung s5 and I don't see my source holding it back or anything. They do scale well. Also for me the lz a2s smallest yellow tip seems to offer the most comfort and best seal so far. I wish I had the spiral dots. None of the spin fits sealed well for me.

Well MMCX has its own share of problems. You're trading one uncertainty with another.
