Professional 70M(230ft) ARC HDMI Extender (HDBaseT), UHD 4K@60Hz with HDR10 & 3D Effect, S/PDIF Audio, Audio Return Channel, EDID Management, HDCP 2.2, 2-Way PoC + IR + RS232, Over Cat 5e/6/7 Cable

After buying multiple HDMI balun extenders to send a eARC/ARC signal over ethernet between a LG TV and Samsung Soundbar, none of which worked, THIS product works great.Literally, plug and play! - connect it all up as instructed, power up everything and you are done.I had an issue with the transmit and receiver unit being the wrong way round, the instructions are incorrect on which unit should be connected to which piece of equipment BTW. Once I worked that out, everything works great. No more ugly HDMI cable between the TV and soundbar.

Works like a charm. My AV is located in a different room so needed a devices that would extend HDMI ARC over Ethernet. Sound quality is simply superb. The only thing i have noticed is that on rare occasions, the sound drops for a micro second and comes back. I am still trying to figure out whether its my setup or the device. I am suspecting the device as i have tested the ethernet cable + AV setup. Could be a fault device but i am still investigating this issue.Apart from that, works perfectly.

This product is amazing.Initially I had problems getting it to work properly, but found out it was my own fault, having modified my display driver to expand the freesync range on my PC.This badboy extends my AMD Radeon Vega 64 graphics over a 22 meter cable, running 3440x1440p@100hz with freesync. One thing to note. Initially my display showed up at 60hz. But by creating a custom resolution using AMD's own driver software and setting it to 100hz. The device then started running.Yes, it gets hot. In my rack cabinet, where I have my gamer PC, I have mounted fans, that cool everything, including the extender transmitter. I consider to add some heatsinks to the one in my office. Because I want it to last long, because it's so amazing.Zero lag ... zero lag !I have also, because I'm a tech nerd added a Hue smart plug, to the device and controlling it via the hue API, so when it detects my PC shuts down, it turns off the extender and vice versa, when it turns on. This way I minimize, the time it's on.For the price, this device deserves 5 stars.

We had a faulty unit just out of guarantee so purchased a new unit. I asked if we could send them the faulty unit for a chargeable repair - they said ‘cheaper to buy a new one’ for £295!

Expensive, but worked like a normal HDMI cable across CAT6 with the added support of IR forwarding. Recommended.

Unfortunately I couldn't get the unit to work, I managed to get power to both units though nothing else. I tried 3 different CAT6 cables, two within the fabric of the building and one loosely. Two have been verified as sound and are roughly 15m in length. A refund seemed to be the only return option which seems silly, I will need to source an alternative.

I was trying to take ARC HDMI output from my television to a Sonos AMP. My television is in one room with Cat6 cabling to a set of Sonos AMPs in a cupboard. Other HDMI Extender products didn't work and they ran especially hot. What was required was an HDMI Extender designed for an ARC (Audio Return Channel) HDMI connection. This is the only product that I could find that specifically addresses ARC connection. It worked right away and after a few weeks I have had no problems with the product.

I needed this to replace an older HDBT installation that was not able to support 4K with HDR - and lacked ARC. I tried a number of devices before this one so was pleasantly surprised when this fired up straight out of the box - No configuration required, just worked. Great value compared to more expensive solutions out there. Handled Sky Q UHD, 4K HDR Blue Rays + PS4 in HDR mode.
