Title: Outstanding Bluetooth Transmitter – No More Cord
Review: J40 Transmitter works perfectly with my home theater plugged into headphone output jack. Fast pairing with my bluetooth earphones. Good range over 30 ft. No voice-picture lag producing perfect lip syncing. Transmitted sound quality is good. The J40 battery lasts well over 5 hrs of transmitting. Have not tried J40 as receiver. This J40 Transmitter has eliminated the need for headphone cord while watching TV without disturbing others. Highly recommended.

Title: Good, not Great
Review: I’m not sure the J40 transmitter/receiver is noise cancelling. It paired easily in both TX and RX modes. The markings could be better. It is very hard to read the RX/TX switch. The manual has very tiny print making it hard to read for us with old eyes. I haven’t figured out how to get the greetings in English. It does what it says it will do for a very reasonable price.

Title: Simply put, works
Review: The only thing not to like about this product is the incredibly small type instructions – requires a magnifying glass. But… this truly works great, holds charge, and delivers Bluetooth to those older devices (e.g. portable CD player) lacking such. 5 stars

Title: Works great and play time is amazing
Review: Bought to use in my 2013 Mustang due to my Bluetooth going out. Plugs directly into the aux receiver or with the longer cord. Playback sound was great as well as the battery life. Used as a handsfree device as well when driving and call quality and volume were good as well.
