I did. It did indeed remove pressure build up. The widebore version seem to widen the stage too

So after switching around with alot of tips, what really feel best (sealed and no air pressure build up) in ear with m9 is dunu s&s size S for me

Can i have a list of what you removed?

Tbh, i dont think the charging corrosion is the issue , look at sony xm4, 5 , ifi go pod, all used exposed charging interface and none of them have issue with charging so far

After owning the N5005 for half a year and switching around so many iems, I still think N5005 is on a class of it own. I recently bought a zx707 and pair them with n5005 to test it out, and holy cow, the bass hit hard, like viscerally sub bass while treble is up in the air.

I noticed that my zx707 (Japan) can't find my 5Ghz home wifi, while my phone can just fine. Do you think it's regional incompatible or something else?

Yeah hires seem to upscale to 32 bit 192khz everything, correct me if I am wrong tho

It's weird that zx707 don't have bit perfect stream but upscaling stream instead

I think it's same as zx505, so 1500 mah. I read that somewhere

Unfortunately, it's both. I own the later and still have issue with charging,

It sound good, but I would not recommend utws5 since they have issue with charging because of design flaw (read the first review of utws5 on headfi)

Well my first impression on the 707 is that the battery is definitely better, and snappier (huge SoC update) Soundwise, it has better stage image, more treble and airy, but lose the tight bass from the 505.

Yes it's JP imported so I'm pretty excited to buy it But I am really wonder if it's worth to move on from my zx505 (which I unlock bootloader and modified kernel to make it last 12h listening offline)

Appreciated, i got a deal with a used zx707 at 530$ and i need some opinion

Can anyone comment if the 707 is a worthy upgrade over the 507?
