5 out of 5 stars   These work great!
By Just some dude who bought something (Wisconsin) March 16, 2012
Review submitted for Sony MDR-RF970RK 900MHz Analog RF Wireless Headphones (SNMDRRF970RK)
Verified Purchaser
Pros: Durable, Good Bass, Great Sound, Comfortable, Good Value, Easy to use
Cons: None here
Other Comments: These are a good buy, easy to set up, and a no brainer to use. Pick them up off the charger, put them on your head, and they are on. Take them off and put them back on the charger, no on/off switches to fumble with. Very nice!
I recommend this product Yes, I recommend this product
