Great Things Come In Tiny Packages
This device is small, but packs a punch. I use it with my DT770’s. I have an AptX HD transmitter plugged into my TV’s SPDIF out. The EarStudio is linked to it and plugged into my DT770 headphones. The EarStudio drives the DT770’s to way beyond loud. And I have yet to run out the battery on the EarStudio; I estimate it can run off a full charge for at least 24 hours, which is incredible. Bottom line: I’m very, VERY happy with this purchase, and the sound quality is AMAZING, beyond any Bluetooth audio I’ve used before. Definitely loving the AptX HD. You will too!

A Bit About LiFePo4
2 of 5 found this helpful To the guy complaining about these batteries not holding a charge, these batteries require chargers SPECIFICALLY designed for LiFePo4 batteries. A standard LiPoly charger won't charge them properly.

Love it!
I like it better than the original Arduino! Better board, 100%!
