Pros: Replacement of power supply is a 4 year old 1U rack computer. Work as expected. Brought from Newegg because of the super fast deliver. Going OEM can be an option, but will take much longer for delivery.

Cons: None

Pros: Sound is balance and good. Great bass. Price is very good. Battery life is excellent. Over 8 hours a day

Cons: Very uncomfortable. Would give 5 egg, if more comfortable. Very hot after a while. Hurt ear.
