LiNKFOR Digital Optical Audio 1x3 Splitter Digital SPDIF Toslink Optical Fiber Audio Splitter 1 in 3 Out Aluminum Alloy with Optical Cable Support 5.1CH Dolby-AC3 DTS for PS3 Blue-Ray DVD HDTV

it works. sound improved. I have not tried hearing aid and sound bar, so not comment there.

As a matter of background information, I recently purchased a new 4K wide-screen 75" TV. The TV I had previously was a 15 year old professional Samsung Plasma set which had more different types of connections than anyone could possibly use - and those connections spoiled me (that TV cost me $3000 some 15 years ago). Well, with many of the new 4K models, older connections such RCA or 3.5 MM outputs, are no longer there and most of what you're left with are HDMI, Toslink (sometimes digital coax) and USB outputs. This left me with a dilemma. I have a Yamaha soundbar/subwoofer unit with an RCA input and previously, I would run a toslink cable from my TV set to an SMSL Digital to Analog Converter (DAC), and RCA cables from from the back of the DAC to my sound bar. This has always worked for me. But I also have wireless headphones (2 sets of them) and I used to connect 3.5 MM audio cables to the transmitting bases - but no more.So after evaluating a series of different toslink splitters on Amazon, I saw that many were actual switchers that you had to either use a small remote or manually push a button to use the toslink output needed. This new LINKFOR toslink splitter is just what the doctor ordered. I now have the toslink running from the new 4K TV to the back of my DAC on one output, while the other two toslink cables (connected to the other 2 outputs) are running to my two wireless headphones (different models and brands) that have Toslink connections on their transmitter bases - wallaaaaaaaaa!And this LINKFOR works superbly. It splits the signals without affecting the strength or sound - and you don't have to use a remote to select which input you want (that was the big thing).Now you do have to plug the unit in. Since it's on a TV set, I connected an AC line plug to the USB cable (5V 2A), and just plugged it in. I couldn't be more satisfied with an electronic product. This unit only comes with one toslink (digital) cable and one USB cable for the power. Now if you have this near a computer (such as on a desktop, near-field arrangement), you can just plug the USB cable in to power the unit. However, anywhere else, you will need to get an AC plug (the ones where USB cables connect to them).This is one splitter that really comes in handy without any other gimmickry - highly recommended.

I bought this for splitting the optical out from my TV to a soundbar and Sennheiser RS 175 Wireless headphones. I checked the sound quality and volume level with and without the box. Sounded exactly the same. The beauty of this product is that it powered by a USB plug that you can connect to your TV. The box powers off when the TV is off, so it isn't always burning power and cooking the equipment. It is also super convenient to not have to find yet another AC outlet to plug it in, like some other devices. The reason you purchase a powered or (active) splitter instead of the cheaper passive splitter is that the signal gets rebuilt before being sent out. In this way, you don't lose any quality with that could happen with a non-powered/passive splitter. All in all, a great little, well-made product.

Splitter is working well with sound bar and TV ear phones.

Purchase product to split signal between tv & sound bar to allow signal to go to sound bar and device to interface with hearing aids. Tried a non powered splitter before trying this unit and the non powered splitter would not work with my sound bar. This unit was easy to install, and it works.

Good product, fair price

As described

I used this to connect my soundbar and connect to a Bluetooth transmitter that transmits to my hearing aids. I have used this setup in the past with two different Yamaha amps and had no problems at all (except the amp went out). The problem with this Linkfor product is that there is a delay between the devices connected. I have only connected two devices and it's unacceptable. I can't imagine how much worse it would be if you have more devices connected. The result is that is sounds exactly like an echo, a severe echo.If you plan on using this with only one device it would work ok but, then again, if you only had 1 device you wouldn't need this.Bottom line is that if you plan on using more than 1 device at the same time, I wouldn't buy this. Unless you like hearing a substantial echo on every device.
