I bought them for one purpose, to use while streaming live music on Twitch. I've had them for 2 and a half months now.
They are quite pricey. They deliver what I bought them for, but for the money I would have hoped for better sound. But in terms of low-latency live music creation, there is no competitor.
The only alternative is a combination of wireless IEM system and in-ear headphones used on stage. That combination is close to the price of these headphones, and you still have cables from your ears to the receiver which you have to attach to yourself. These are just headphones you put on and off, no cables. Saves me a lot of hassle when I take a bathroom break while streaming for hours.
The feeling of freedom from cables is unprecedented. I can move around, switch instruments with ease, and no longer have a cable around my body. I love it!!!
I create music with lots of live looping with Boss RC-505. The headphone transmitter is plugged into the headphone jack of Scarlett Focusrite 2i2 for monitoring. I haven't noticed any latency problems. In this regard the headphones are perfect.
However, I was disappointed with the sound. I checked and my modular pieces are the highest quality they offer. I was going to buy an upgrade if they offered one!
I had these Lewitz HP710 headphones before, and they delivered a much larger soundstage and more volume. I had gotten used to a particular way my voice sounded in my ears when singing. It had more depth and detail, and it allowed me better vocal control. In comparison, the AIAIAI were small, quiet and I was barely able to register what's going on. It was a huge uncomfortable adjustment that took me a while. I always have to keep the monitoring volume high.
Now that I've gotten used to them, it's fine. I can sing without discomfort. But it makes me wonder what I am losing out on, and for this price that's a disappointment.
There's the possibility that my previous headphones were too loud and I think it might've been affecting some hearing loss (ringing in ears after use). So in that regard maybe this is a good change.
They are quite comfortable to wear for hours. Even more comfortable than my Valco VMK25 (but with worse sound and no ANC). Battery life is also decent.
I would still recommend these for live streaming use, even with my complaints about sound and price. Freedom from cables is just so good. I wish they'd offer upgrades for better sound.
