Compared to other Wide-Band Receivers i believe its the best price, the battery lasts for years from what it seems.
Also i want to say that "It can take a hit" i mean its sturdy enough to fall without breaking.
Coming back to the sounds it can make, they are very nice even raw straight to the headphones also something to be careful about is using somewhat good cables because some can bring interference.
Come close to phones, routers, lambs even touch the front pins on sheet metal, metal polls outside, trashcans whatever.
Also buy some cable and strip the ends and touch it lick it, anything that comes to mind.
I tried passing one pin through resistor,pots, and also try playing with it on modular stuff.
Ultra nice even for walks ! Forget about Spotify and your phone take your headphones and take a walk, i even slept once with it.
Thanks Soma !
