I've just got Tingker H6 on last sale, and while it's not the H16 and I have never heard other full BA before, maybe my quick impressions could be helpful to you.
Hi all, like to know what's your opinion for H16 at this price(USD 98)? I currently have s12, Truthear Hexa and Audiosense DT600 (which i enjoy and used the most). Mainly listening to Jpop / Kpop and live music monitoring. OR better go for other option like Geek GK200 / Aful performance 8 or etc?
So, H6 has a large quantity, punchy and fast bass, mids feels veiled and the elevation in the pinna gain is abrupt and could be shouty at times, but they also can be very detailing. I have a PR2 v1 which should be close to your s12, and I think PR2 is very dry while H6 feels dehydrated in tonality... the completely opposite of my warm Simgot EA500. Someone said in a review that H6 felt between DT300 and DT600. I don't know if H16 follows the same tonality of H6 with improvements, but if so that's what you should expect.
