Pros: Small, noiseless system perfect for a home theater system or a kiosk.

Cons: Buggy when connecting to HDCP 1.4 equipment, bios update did not help.

Overall Review: Was working great for Kodi theater but iTunes would die playing protected content. I bought a Blackbird 4K Pro HDCP Converter box that converts from 2.2 to 1.4 so HDCP is supported through my receiver to my display. iTunes could properly play movies when connected that way.

Pros: Easy to install, great performance. Brought new life to my laptop which is now more responsive and much faster booting. Probably the most worthwhile upgrade one can buy.

Cons: none.

Pros: Good sound, light weight, cord free running

Cons: Doesn't pack well in luggage or gym bag

Overall Review: I bought these because I was tired of tangled and flailing cords while I was running. So very glad I bought them. Sound quality is quite good if not top of the line. Highly recommend for work out ear buds.
