What people are saying

Rated 5 out of 5 by from Awesome wireless device. The LG WOWCAST works as described and produces quality wireless audio between soundbar system and TV. I recently purchased the 65 OLED G2 TV and paired it with the S95QR Soundbar system. I wanted to minimize cables so I purchased the WOWCAST. The device mounts flush behinds the tv and does not get in the way with wall flush designed TV's (galleria editions, frames). I'm am very satisfied with the transfer of audio quality and I highly recommend this product.

Rated 5 out of 5 by from Lose the wires [LG WOWCAST] So here is a way to wirelessly connect the TV to your LG sound bar without the loose of Dolby Atmos functionality. I was worried I would lose somthing when I ditched the wires, but my experience with full Dolby Atmos was still great. I did not notice any additional distortion or sound issues. So it says that it can "Stream up to 12 channels of uncompressed sound", I am unsure of how to verify that, but it does sound great! WTP3 WOWCAST (ok crazy name) allows for a no cable connection from the sound bar to the TV (cool).

Rated 5 out of 5 by from LG's Top-Notch Audio Dongle LG's WTP3 WOWCAST was just what I needed to wirelessly connect my TV to my LG S90QY Sound Bar. It features 7.1.4 transmission and Dolby Atmos. If your TV offers an HDMI ARC or eARC, this dongle is a great option. The WTP3 is all set to go the minute you plug it into your TV. It's the easiest part of setting up a new sound system. No wires/cables needed. I've found the audio from my sound bar to be phenomenal using the WOWCAST. I've found no issues with the Wi-Fi connectivity. The clear sound coming out of the sound bar is welcome. The compact size of the WTP3 is helpful. It makes for a cleaner home theater. It is plug and play, even for folks who arent electronically proficient. All in all, LG made a must have dongle in the WOWCAST. Highly recommended.

Why is the Dolby Atmos setting disabled and unable to be enabled when I connect WOWCAST to my C1 PUB? My sound bar is a S90QY. They are connected and working but I am unable to enable Dolby Atmos

Asked by: CraigInWA
The LG WOWCAST WTP3 features an HDMI ARC port and an HDMI eARC port. When connecting it to your LG C1 Class 4K Smart OLED TV w/AI ThinQ® series TV, make sure that you are using the HDMI eARC port on it to connect it to the HDMI eARC port on the TV. HDMI ARC doesn’t allow you to bitstream the full-fat high-quality codecs such as Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio or DTS:X soundtracks that you find on Blu-rays and 4K Blu-rays. It simply strips out the core 5.1 data stream. If you want this level of functionality, you’ll need HDMI eARC...^Ivan

Will this work with SP8K rear speakers?

Asked by: Chazbro
The LG SPK8-S 2.0 Channel Sound Bar Wireless Rear Speaker Kit already has a wireless receiver that receives signals wirelessly from compatible LG Soundbars. You do not need the LG WOWCAST WTP3 for the SPK8-S...^Ivan
