Korus Audio V400 Premium Portable Wireless Speaker (Expands to a 4 Speaker System)

Provides a great alternative to wired speakers. Allows me to integrate my Sirius, Iheart, itunes and personal music from all my sources throughout my home.

For the first 9 months, it worked perfect. Then, the sound dropped significantly to about 15% volume. I didn't use it much after - just once in a while. After another 8 months, the volume is gone. It powers up, but no sound.

It's a very good speaker system, much better sound than Beats Pill (we have both). However what I do not like is that the speakers do not come with an Android Baton, and if you want one it is $50, which is ridiculous. Also the speakers cannot be panned so one is left and one is right for true stereo.

I gave two stars because it looks really nice, polished, heavy and solid and the sound is ok....but..- The dongles, seem like a "new" Bluetooth-like thing, and it limits you, if you lose the dongles you are to buy some others at $$$$ price- The connection/range is not good at all, I had the iphone with the dongle next to, and 10 ft away from the speaker and the connection was very choppy (deal breaker) -- but in this case I give the benefit of the doubt and probably got a defective product..nevertheless, it is going back for this reason.- It is no WIFI or BTI can see the use case for this speaker as follows: (assumption is that their connection technology is substantially better than BT)If you are in a WIFI-dead spot in your house and for some electromagnetic cause your BT does not work either. Note that you have to be in your house or where AC power is available -- as this speaker does not have built in batteries. I don't get why they did not make it BT compatible.

This speaker is great!! It has clear sound and comes with everything you need to plug in to the various devices you can use. The sound levels are great. I got this speaker for my kitchen and it definitely serves it's purpose. I would recommend this item.The only bummer is that it doesn't use batteries, so it needs to be plugged in.

Bought this a year ago and now it doesn't work with iOs 11.0 and is completely useless. There are apparently no updates available.

This item the sound is great, the only problem is that the adapters are not long enough so you have to take any case that you have on your phone off so you can connect the adapter, other than that the product is great

Have one V600 and 3 V400s positioned throughout a 2500 sq ft home no connection issues. Sound quality on both may not be perfect, but strong for the price point. Enjoy simplicity of baton-SKAA system. Usually play music through laptop. Therefore, avoid potential commented issues with baton/dongle fit to tablet/smart phone. The latter would particularly be a challenge due to case. Don't keep tablet permanently encased so perhaps less so. Only wish limit wasn't 4 speakers, as I'm maxed out and would love to cover one or two more areas. Nonetheless, very satisfied.
