Previously had problems with my Philips 65oled865 with (only) ARC and the Bose Soundbar 900 with eARC, Sub and Rears. Audio lag was extreme and only enjoyable with Stereo PCM 2.0. Even with a new Blu Ray player, the sound was delayed via HDMI via TV to the soundbar. The Philips TV with top picture but general sound output problems via HDMI and optical.
Thanks to the VAX04101, all problems are gone now... Sound and picture from all sources are absolutely synchronous and I can now also enjoy the latest sound output formats such as Dolby Atmos etc., or exploit all the advantages of the Bose 900... I am very satisfied with the product . Thanks very much!

Distribute an HDMI signal from a satellite receiver Vu+ Ultimo 4K to a TV Philips 55OLED803 via a 2m HDMI cable and to a TV LG Electronics OLED 55B7V via a RUIPRO 8K HDMI fiber optic cable 12m and so far everything works, but had to operate the splitter with a 5V power supply otherwise no picture comes.

...and that seems reasonable enough to me. Sounds tentative. Well, the desk lamp only gets 4 stars in terms of light output. The lamp has to light up monitors more than 48 cm high for me, and there is a problem with the illumination range on the desk in the dark from the window, as sufficient for pleasant book reading is just under 50 cm radius under the light element at its full power and height of 50 cm over table surface. The further away there is (normal) loss of light. The flat light element has no reflector. The table lamp has 3 joints and is therefore ideal for use behind monitors. The absence of glare is logically a matter of setting - who is so stupid as to let the lamp shine in their eyes with daylight output??. The setting options on the control panel are self-explanatory and logical via touch points. The wireless QI charging also works with mobile phones with a protective cover. The QuickCharge field is also defined visually - only if you put your phone down wrong will it not get charged (that to the negative reviewers). Now to the design, look and feel: everything is just great for my taste, compensates for the small light deficiency, because if you need more light, you can simply put up two such lamps and the whole desk landscape is illuminated.

No more cracking and noise.

The entire technology for television and hi-fi had to be banished to the closet. So infrared extensions were needed for the devices. I've looked at many and read the reviews. The first thing that attracted me to these was the price, then the reviews. They were all test subjects, but they were right: the small, compact extension is optimal, unobtrusive, sufficiently long and works excellently. I can just recommend her. I am not a tester and bought the extension as normal.

All working as expected

This does exactly what you'd want it to do, no messing around and fairly plug and play. My use case: I have an LG C1 with eARC, several hdmi 2.1 devices and an ARC only enabled soundbar (Sony HT-NT5 with wireless surrounds for a 5.1 setup). With standard ARC I could only get compressed audio or stereo PCM via ARC. Enter the feintech: it gets power with an included usb cable, I plug my eARC out from the LG into the labeled output, and then plug the other output into my soundbar in a standard input (this is important, don't use your device's HDMI out, the whole point of this device is to pass sound IN). Make sure you set the physical switches on the device to eARC ON and EDID to output 2 for this use case. HDMI-CEC works exactly as you'd expect, my devices turn on and off, adjust volume, switch inputs and mute as normal so the adapter is effectively transparent. A bonus: you can also use the provided input (hdmi 2.0b ONLY aka 4k 60hz, no Dolby Vision or VRR etc) in this mode to make up for the fact you lose a tv input to eARC. If you have more hdmi 2.1 devices than your tv has ports you might need to look elsewhere for a solution. Additionally for LG C series users, make sure you turn on eARC support in sound settings, and set audio output to “passthrough” rather than “auto” for this to work correctly. This is just a quirk of the TV rather than anything to do with this adapter.

Does what it promises. Highly recommended.

A super charger that charges two devices in parallel and quickly without producing excessive heat. There are also no annoying beeps or whistles to be heard. I like the compact shape and placement of the sockets opposite the plug. Overall, it makes a high-quality impression and is a very good choice for the price.

I want to commend the Heimtech team, the customer service is always very friendly and informative!
as well as binding in all technical areas.

• Now to the switch hdmi eArc Pass, it is a real problem solver for soundbars and HDMI sources, streaming services - via Apple TV 4 k.Box Blueray Player - Fire Tv Stick 4 k, etc. For sound and picture just great.! with the right digital input on the Switch 7.1 eArc To– Sound
• hdmi input playback - source, and to the hdmi out to the projector or television, it fulfills all purposes.

•Dolby •Atmos is output on the Apple TV 4k with the correct settings for picture and sound.
>< 50 hz SDR, Croma 4•4•4 Adjusting the image and dynamic range is important, Apple will do everything automatically.

I use the switch with the Sennheiser Ambeo soundbar, the sound is also output without any problems with the Bose 900 soundbar,,,I've tested and tried everything without any restrictions, with image and sound transmissions.

•What I really like about projectors and older television sets that don't have HDMI Arc is converted to eArc with the switch
and supports. I use high-quality hdmi cable Supra AOC 2.1 - for the image to the projector, for the Apple TV
The Audioquest Pearl 48 for the playback source.

.I recommend the switch great product.! Has solved all my problems.

I use a pair of speakers to improve the sound quality on the TV and already had a Bluetooth and HDMI adapter connected. With the first the sound was muffled and there was high latency, with the second the sound quality was so-so, but it didn't remember the last volume setting and almost caused a heart attack every time the TV was switched on again. One last try, reviews on the French site were very helpful. Sound sources switched to PCM, CEC activated, the FeinTech connected to the 5 volt / 1 ampere connection of the TV (this USB cable was included). A RCA cable to the adapter and speakers and the HDMI cable from the adapter plugged into the ARC connector on the TV. FeinTech switches off with the TV, the speakers do the same via an ALEXA/WLAN socket and when it is switched on again, the FeinTech remembers the old volume, the sound quality is very good and the TV remote control controls the volume of the FeinTech HDMI adapter. I am very happy with this solution.

Unfortunately, the purchase of a 4K TV brought with it the problem that I could not loop the 4K (4K, HDR(10/10+) or Dolby Vision) signal through my old AVR (only 1080p was possible there) and with it that HDMI video/audio signal didn't get into the TV (through the AVR). Some manufacturers of UHD-BR players have reacted to this and have given their device a second HDMI output, with which the sound can be passed on separately to the AVR and the image signal can be routed directly to the TV via the first HDMI output. Anyone who calls an Apple TV their own is not one of them. So a solution was needed. With this device, Fein-Tech offers an elegant and cost-effective solution. You can connect 4 HDMI (image and sound) sources to the Fein-Tech and split the signals there into (4K) image and sound and then send the high-resolution image signal to the 4K TV and the sound signal to the ( older) AVR. It all works without any problems and you can continue to use your older AVR.

The device is easy to install and does exactly what it is supposed to do. Using two devices (as a transmitter and as a receiver) you can - as in my case - bridge the distance between PC and audio system or easily integrate headphones or earpods.

Got the part between my X-Box Series S and my Samsung 4k TV and I can't see any deterioration in the picture. What I was looking for was the optical output because it is broken on my TV. Everything is easy here too. Unfortunately, DTS is not transmitted, but maybe I wasted something there. I get Pro Logic 2 and it fits me perfectly.

Does what it's supposed to and super fast too. Until USB c has become the standard, combination of USB a and USB c is awesome. The charger feels high quality and I am absolutely satisfied with it.
