- Lowest noise floor of any Bluetooth audio I've used so far (although I haven't used a great variety of these). I'm personally hearing none of the "hiss" that most units in this segment suffer from.
- It gets more than loud enough for me; I need to keep it below 75-85% on my phone to be at a comfortable listening level (about 5-10% more volume than when plugged in to the same phone).
- I find the sound from Trinity's on-chip dac/amp very neutral, less colored than the on-board iPhone one.
- Last thing, the BT signal is STRONG for me. At work I passed my phone through the x-ray machine while I walked through the metal detector the audio didn't drop. Didn't even realize what had happened until a minute later, totally seamless.
Very happy to hear you are not experiencing any noticeable hissing.
I'm a bit disappointed as I asked Trinity to ship with my Master 4. No reason to get without an IEM to see ifs acceptable length and audio quality. They shipped ahead of my master 4 and the return period will expire before I receive the Master 4.
Oh well
