Earstudio ES100 mk2

Earstudio ES100 MK2 bluetooth receiver, dac / headphone amp. This tiny thing just sounds impossibly good. If you want to use a wired headphone while leaving your phone free, this works wonders and sounds better than plugging into the phone. If you are thinking of getting true wireless adaptors for earphones with mmcx connectors - consider keeping your wire and using the this - it sounds much better than true wireless BT adaptors.

ES100 Rocks!

ES100 has an excellent APP to control it perfectly The built in equalizer gets the sound right. It’s small and impressive.

I can use my ALL my wired headphones

Amazing feat . I can use All my wired headphones now, with the inept Apple Ipad Pro and Iphone , that lack a 3.5 mm jack. Take that apple. The Software granularity and saving of presets in the device itself complement a really clean bluetooth DAC . It drives even big studio headphones , like Beyerdynamic DT 770 Pro. I can use finally my iOS synth collection and listen to proper dynamic sound om ipad/iphone.
