This is a vacuum tube headphone amplifier from Elekit. I purchased it at an auction because a friend needed it, but they didn't like it, so I'm putting it up for sale. I've listened to it with headphones and as a mini-watt amplifier with bookshelf speakers, and it sounds quite good. The included accessories are a stereo speaker cable with a headphone plug. I will revise the listing as the buyer only wants the unit itself.
