IEMs in ears, power on M11, listen to a few tracks. It's as quiet plugged in and powered on as not plugged in. Between songs, other than recorded noise, I hear nothing. Listening to tracks, still nothing during quiet passages. Having said that, nothing is ever totally black, and electronics...

I have the M11 (not pro) and T800. I use a pure copper cable and 4.4 balanced input, and have no hiss. The high end is hot though, but I don't find it too much.

I've found this cable to be an excellent match at a decent price: https://www.aliexpress.com/item/4000097502378.html?spm=a2g0s.9042311.0.0.7e794c4dWxRuPE

I tried Hakuzen's 175 with the T800, but then switched to a pure copper cable, and it is significantly better, particularly the bass.

I have the P1( and the T800) but don't eq it. While it doesn't have amazing bass the sound is amazing. I find the P1s to be incredibly sensitive to tips and position in the ear. For critical listening, the P1s are my go-to.

Anyone have any insight how the AQ3 might compare with the ISN H40? On another note, I had cable 175 on my T800s and switched it for cable 90. What a difference! The T800s sounded weak in the low end with the 175, but with the other cable the bass is suddenly there.

Interesting you find the lows muddy. I find the low end great, even compared to my DD iems (but not as good as the DD iems). I should mention I’m not using the stock tips and am using an upgraded pure copper cable with balanced 4.4 input. So, not apples to apples with your experience.

I’ve been running my T800s with my M11 (and other things for comparison) and it sounds fantastic through the M11. Seems like a great pairing to my ears.

I just bought two 175 cables in 4 core for $90 each (one mmcx and one 2-pin). The price was the result of the store coupon + 5% Hakuzen discount.

Which seems like it would then be the 175?

I use mine for music, and nothing else. Can't help you. I'd guess many others are the same.

Not sure if this is different info than the info about a flagship, but I've heard that there is a T800 coming (T800 Pro?) with replaceable tuning nozzles which will be available after about April. ...and the current T800 is still in production.

Thanks. That’s super helpful

Have you got a link you could share for the 125? I'm not finding it at the price you're suggesting. Or do the 11.11 prices change once we hit 11.11? Thanks
