Review: Good cable, but not for Phone to TV. - This cable is thin and lightweight. I purchased it for travel, when weight is critical. It worked fine with my Fire Stick, but would not connect my Samsung phone to TV from the HDMI adapter - this requires a thicker cable - the reason related by seller:"That cable uses an active chipset to boost the signal since the cable is so thin. In rare cases, devices like your phone can be incompatible with the active chipset."
Review: Great cable - It works well, it's nice and thin, and it reaches a little more than I thought it would. The only nitpick I have is that there are 3 separate labels all telling you the one side is for the TV/Monitor - but that's probably to try to deal with the folks who don't know how redmere works.

## Features

- High-Speed HDMI with RedMere Technology: This active RedMere cable supports all High Speed HDMI features, including 4K x 2K video resolution, full 3D pass-through, Audio Return Channel (ARC) for A/V receivers, and an Ethernet channel for Smart TV networking—eliminating the need for additional cabling.
- Active Signal Boost for Long Runs: The active HDMI cable features a built-in booster and equalizer chipset that transmits HDMI signals and 5V power farther and more reliably than standard HDMI to HDMI cables. It’s the ideal solution for 4K displays or low-power HDMI sources such as tablets and compact media devices.
- Unidirectional Design for Reliable Connection: Direction matters—this RedMere HDMI cable is NOT bi-directional. Labeled connectors clearly indicate the TV (Display) and Source (Device) ends for proper installation. The embedded chipset in the TV end amplifies the signal for stable, high-quality transmission.
- Ultra-Slim & Lightweight Build: Combining gold-plated connectors with molded strain relief, this flexible 36 AWG ultra slim HDMI cable features solid copper conductors and weighs only a few ounces. Its lightweight design ensures a snug and secure fit in vertical HDMI ports or compact setups without putting strain on your devices like heavier HDMI cables.
- Perfect for Tight Spaces & Wall Mounts: This low profile HDMI cable is ideal for flush wall-mounted UHD TVs and tight installations. Easily pair it with an HDMI extender, HDMI switch, or HDMI splitter. The thin, flexible HDMI cable coils neatly for quick and clean setup in crowded entertainment systems.

### ⭐⭐⭐⭐⭐ Fantastic HDMI cable
*by G***R on August 22, 2021*

This is so much better than the thick 15 foot cable I'd originally been using to connect my PC to my plasma television. That cable was so thick and stiff it lost its grippability and would disconnect every time I moved my PC so much as an inch in one direction or another. In two months or so of use I've had no connection problems as some have mentioned in other reviews. To clarify, my PC is connected to a Sony A/V receiver feeding to my TV.
