Just got my Get, and here are my brief impressions; but first, a bit of background:
My main IEMs are Etymotic HF5s, which are not only very low impedance (16 Ohms), but are also very sensitive (105dB/0.1mV), and very isolating. As a result, I usually listen at the lowest volume setting on my iPhone 7, and even them I usually use the EQ settings of my music player to drop the level down another 16-20dB (!) or so.
So I'm kinda sensitive to hiss, which is why I ordered the Get in the first place, to see if the analog volume control helps.
(FYI: My previous Bluetooth solution was the Westone Bluetooth cable, for which I modded my HF5s to accept MMCX connectors - yeah, I'm a little extreme.)
Unfortunately, the high output gain of the Get means that the hiss is way too high
. The volume wheel only appears to attenuate the audio before the output stage, leaving the noise floor unchanged.
Meanwhile, my main headphones are the Fostex TR-80, which are 80 Ohm dynamic headphones. The Get fares better with these; the noise is not noticeable in normal listening, but it is apparent when playback stops (it's especially noticeable when the Get turns off its output stage about 10 seconds after playback stops, and you realize that the Get wasn't actually silent until that point).
Haven't tested range, since I usually don't stray too far from my phone.
