This works perfectly with my set up - external output from the back of my TV using the 3.5mm Aux Out jack, and getting power through the USB cord plugged into my power strip's USB charging port. The packaging was sufficient. The box was a box, nothing special there. Three plastic foam pads kept the individual components from knocking into each other and the sides of the box. The components were wrapped in plastic bags and held closed with a strip of cellophane tape - all pretty standard. The setup went well enough except for one snag: the 3.5mm-to-RCA Component plugs needed a bit of care. It looked like at some point inside the assembly plant, someone had stepped on the red RCA plug, deforming the outer contacts of the plug. I had to take a couple of minutes to gently bend the outer parts of the plug back into shape. It's understandable that accidents happen, but still... Fortunately, I got them to work without any other issues, so I'm still giving this a 5-star review. Looks and Feel, somebody really did their homework because they nailed it on the 1970's retro aesthetic. While I know that the wood grain is just a cheap veneer, the underlying material feels good and solid. They have a decent bit of heft to them. While I'm not inclined to inflict any abuse on them, they seem like they'll handle an "accident" or two. And the legs have a nice bit of rubber on the tips so they won't go ratting and buzzing around like someone is blowing up your phone while it's out on the table. (That said, keep some rubber cement and alcohol on hand - it won't surprise me if I have to go and reaffix these rubber feet a time or two over the course of this product's lifetime.) The control is dirt-simple. There isn't even a power button. Just the volume control that doubles as a mode selection button. Just push it and it cycles through the modes. (Do note that it will skip over "PC Mode" if the USB cable is not plugged into a PC or a hub connected to a PC.) Also, that volume control has a very nice, smooth feel to it, just like a good old fashioned analogue control. It's nothing at all like those "clicky" wheels and knobs that are de rigeur these days. They're not really as loud as I might like them to be, but this is fine since it's just for myself in my bedroom. Although this may just be a technical issue with my TV. That said, this speakers are surprisingly small. They almost strike you as being toy-versions of "real" speakers, but the sound that comes out is real enough. Otherwise, I cannot really attest much to the sound quality as I'm not *that* much of an audiophile. Just that it lacks the "muddy" sort of sound you might expect from a cheap set of speakers that try to be bad-ass bass thumpers. Bluetooth, Line-In, and USB (when used for both power and audio input) all seem to work just fine. HOWEVER... NOTICE: If you use the USB mode as your audio input, YOU MUST MAKE SURE YOUR USB PORT CAN POWER THESE SPEAKERS!!! While their price-point cannot be beat, these aren't the cheap-o bargain bin speakers you pick up in the dollar store. THEY NEED POWER. Remember: Watts = Volts x Amps. These need 16 watts, so at USB's usual voltage of 5 volts, you need at least 3.2 amps! You're best bet is to run these suckers off a USB hub that is capable of Power Delivery, and have it supplied with a halfway-decent power supply. Failure to follow my advice on power supply can result in frequent power-cycling of the speakers, causing some the issues some reviewers have had with the speakers repeatedly connecting and disconnecting their Bluetooth devices. All in all, I feel that this is an absolutely fantastic buy for what you get: a very nice looking little 2.1 sound system where all the thrills and gimmicks are in its utter simplicity and its harkening to "The Good Old Days" of analogue audio systems. I hope that the Cinnkeyi brand sticks around and continues to deliver like this.

Good sound quality but the cables for the speakers could be a little longer.

I am not an audiophile, but I do like my music to sound good. I was looking for Bluetooth speakers for my new PC build that I could put on the desk, away from the PC case. The last Bluetooth speakers I bought were a real disappointment and had too much lag especially noticeable when watching movies. But I liked the look of the Cinnkeyi speakers and I figured with four speaker included, it couldn't sound too bad. I have been very surprised how great the sound is coming from such a small speaker system. Granted, I use these in my studio which is a converted bedroom and not a big space. But these speaker not only provide all the volume I need but the depth of sound is really impressive. If you are looking for high quality speakers on a budget, then these Cinnkeyi speakers are a great choice.

Very low sound. They look nice, install easy and sound decent at their low volume. I wasn't expecting super sound at the price but they have less volume than any PC or desktop speakers I've ever bought.

Broke after less than 6 months---- its been less than 6 months and the speakers have declined in volume so much and are now making a buzzing sound constantly. Were not very good even brand new. Waste of money.
