The sound is great and the distance is phenomenal

Among these are crystal clear sound throughout my 4-story house due to the 160 ft range, the ability I have to pass through the optical cable to have two devices, this transmitter and my soundbar, though I only have one optical out on my TV, and the overall seamless nature of instantly connecting to my earphones with no delay.

Package included a male to male 3.5mm audio jack, an optical cable and a dedicated charger which is best used to power on the device instead of plugging into a USB, because of the subsequent associated noisy static sound in the transmitted sound to the headphones

Portable Bluetooth Speaker - Exceptional Bass and Rich Stereo Sound, Plays Loud, 14-Watts, 100ft Wireless Range, Play 2 together for Music in Dual Stereo, Splashproof Black

And I even enjoy better surround sound, can step away to the restroom and not miss any of the movie!!

Sound is clear and there’s no lip-sync delay.
