For the price it can't be beat! (*only ten bucks!)
It also arrived quickly, shipping very fast.
Optical cable was included and is long enough for most uses.
I used it to hook up my TV to the home stereo.
The "power cable" is just a standard 3.5mm barrel connector with a USB plug on the opposite end that will plug into a TV USB jack or any standard USB charger/phone charger/adapter.
Took about 30 seconds to hook up...nothing special needed. Plug and play.
2 RCA (left %26 right) outputs plus an additional 3.5mm standard mini headphone output which could also be used to feed another amp, recording input, or headphones.
It might not be an audiophile's dream but it's doing well and sounds great...especially for the low price.
TIP: You might need to configure your TV or audio gear output setting to "Optical Out" if you don't hear any sound. This is a "dumb" piece of gear and needs nothing else to work, and I would not hesitate to get another one if the need arises.
Highly recommended.
I am not being paid for this review, and I only review "things" that impress me, be it quality or price. This is both.
I gave it Five-Stars for overall function, price, and appeal.
