What’s inside the box?

  • TR 120 transmitter (audio cable is attached)
  • Transmitter power cord (in a small white box- it’s there, trust us)
  • (2) AAA NiMH rechargeable batteries
  • RCA to 1/8″ Audio Adapter
  • 1/8″ to 1/4″ Audio Adapter

These headphones are very comfortable. I have read some reviews that they’re bulky and uncomfortable to wear. But I doubt that because I’m very satisfied with my RS 120 II. The price is reasonable. Voice clarity of this product is fantastic.
