So I was super hyped for the built in Mic. I mean using top of the line headphones (or near it) to play and get gains in video games is nothing new. People have done it for years with AKG Q701/HD650/Beyers and HD800s. Even Audeze with the GX (sitting next to the Ananda BT right now) are doing it.
The possibilities are endless.
The Built in Bluetooth receiver and DAC/amp has been fairly high quality so far, something you don't see often in fully integrated wireless products (the TWS600 has noise on the line when on) but the Ananda BT's have a fairly good built in USB DAC/Amp setup.
ADC on the other hand, I guess I was expecting too much. Microphone input is workable but fairly noisy. It seems more added as an afterthought from what I'm guessing being an open ADC channel/pin on whatever chip solution (Qualcomm?) they purchased from. Most manufacturers ignore it.
Now something I've noticed from usability pov with the mic...its awkward. It's tiny, short and relies more on being omnidirectional to pic up the operator (pattern found more commonly on say in ear headphones) seeing as how it doesn't require and is far from the operators lips. See the GX to the right. The mic is right in front of your mouth and it is directional.
also noticed some awkward cable mixing with the USB C and mic location...they would have been better flip flopped with the USB C being nearly pointed straight down and the mic situated higher up so it's closer to the user.
Overall, honeslty nothing most of you here care about. The Ananda is a pretty upper tier audiophile open backed headphone. Microphone was probably not on many of your lists.
