I had a blue tooth transmitter on my TV that worked well but linked with only one device. I like having the TV on with a timer when I go to sleep. With the old transmitter I had to un-pair the speaker by my work desk and re-pair it to the speaker under the pillow. This one allows me to pair both speakers at the same time and I only have to turn down the volume on the desk speaker. This is so much easier to use. I may buy another and give it to my house mate so they can do the same. I am very impressed with this.

Update after using this for two weeks

The T-one is surprisingly small and requires only one button to start the pairing process. I plugged it in to the usb on the TV and it was fully charged in about 1 hour.

I use it on the TV because I pair the TV with my echo show that is on my desk. I work at home on the computer and tell the echo to mute when a phone call comes in. It's really distracting to have a loud TV blaring in the background when on the phone.

I also have a bluetooth speaker under my pillow in bed. I like to listen to the TV when I tune it to youtube and play forest sounds for about an hour. I helps to put me in a very deep sleep. Pairing the speaker and the echo at the same time quick and easy.

I got a second T-one for my house mate and she set it up herself. She is very tech challenged and had no trouble at all setting this up in her room. I was very impressed.

The User Guide was very good. There were pictures and instructions that explained how to use the T-One. The type was large easy to read. The charging cord is a USB A and plugs into any USB charger or device that has charging capabilities (most do). The T-One has a battery but I have not tested it to see how long it lasts. This is not an issue for me since if the power goes off nothing works anyway. It is nice to know that I can unplug it and use the charger for something else for awhile.

There is a very slight latency but far less than the previous adapter I was using. Overall the latency is not very noticeable unless you are just super critical. I have noticed that different devices have a little different latency. More in my pillow speaker and less in my echo so I can't blame the T-One. It has to be a lag in the receiving device. I only found this out by placing the pillow speaker near the echo and noticed a slight difference in the audio. Sort of like an echo chamber.

Pairing to two devices at the same time is super easy. Once paired, the devices are remembered and pairing is automatic.

Overall, I am very pleased with the T-One. I am going to get a third T-One for the TV room so two people can use headphones and not disturb the rest of the house.

Swiitech Bluetooth Transmitter Receiver
Receiver mode pairs quickly and when the power button is pressed a nice British sounding lady says Power on Connected. The receiver connects just that quickly with my HP computer. I've gone to my back bedroom and the signal is strong and the sound is clear on receive and the distance was about 45 feet, so the Bluetooth signal is strong.
I used the transmitter with my TV transmitting to a headset. Pairing was a little slower but connecting was quick. Distance in transmit was about 45 feet.
I used the receiver for 12 hours of binge watching and the battery was still good. When charging a red light flashes and turns blue when charged. After 12 hours of use I put it on charge and noticed that the light was blue ½ hour later.

The Swiitech Bluetooth Transmitter Receiver states that it use bluetooth 5.3. I thought I could pair it with an Avantree Headset that is several years old but relies on aptx to reduce latency. I wanted to use it with my drum machine for wireless experience on a flight. However, the even the short latency doesn't work when you are trying to create a beat a split seconds count. However, the Swiitech transmitter/receivers work great at reducing audio latency from a video (TV, movie). I haven't exhausted the battery but it charged quickly and appears to be hold its charge. Audio quality seems good. the headphones I used had a lot bass and that came through. But I need to text with other headphones earbuds. I'll update if anything changes. The vendor does offer opportunity to earn additional prizes or discounts on future purchases. However, I those offers did not affect my review. My hope is that these last a while and their batteries don't swell. I had two Avantree disc style bluetooth transceiver/receivers and their batteries swelled so much it cracked them open! I hope the cells on these are better. Their small design lends itself to many uses and they are light. The screen is a nice improvement over the regular blue light indicators on some bluetooth devices and it also tells you the battery capacity.

I was looking for a 2-In-1 Wireless Adapter that would allow my wife and I to both watch TV in the bedroom with Headphones/Ear Buds on. The set of headphones is wired and needs to be plugged in. The other device is a set of BlueTooth enabled earbuds. The Switttech adaptor T-ONE allowed for both devices to connect and listen at the same time, independent of each other (for volume purposes). Also one of us could turn our device off and go to sleep with out disturbing the other. Then when we were both done, just unplug the headphones and/or put the earbuds in their case and the Swiitech system shuts off after a minute or so! NO Hassle. No fumbling for the Swiitech in the dark.

The model T-ONE claims to operate for 26 hours before re-charging is required, which is equating to about 3 weeks of time before re-charge is required. I'm sure that this is because we are only using this late in the evening and only use this 1-2 hours per night.

Set up was a snap after first charging the Swiitech adapter. Both devices were recognized when connected to the adapter and remembered each subsequent reconnection for both devices. It learned the devices from the inital setup and remembers them upon each re-connection. It doesn't matter whether we are connecting a single device or both. It Just Works!

To set this up, I plugged the Swiitech unit into my cable box, so I can also get my on-demand and recorded shows associated with my content provider. I went through the cable box because the audio from my TV runs directly into the cable box which also supports an external speaker enclosure.

The Adaper came with a charging cable and three ( ) audio connectors so I can connect to any of my other sources, Stereo Tuner, Ipod, Bose Radio, etc. and get my music/content to my other Bluetooth speakers. that I use in various location in and around my house. I just keep finding more ways to use the 2-IN-1 Wireless Adapter. - Thats why I consider this to be "My Best Gadget Find This Year"

When I first opened the package I was surprised at how small the adapter is. Small and lightweight but feels solid. I'm not sure how much charge it came with but it charged up to 100% withing about an hour.

I first tried it on transmit mode plugged into the headphone jack on my computer. I was able to pair several different brands of wireless earphones easily (only 2 at a time). Even my Bluetooth enabled Phonac hearing aids paired right away. I watched a few videos to check for any sound lag. I could not appreciate any lag even with the cheap non aptX headphones. Pretty impressive.

Next, I switched to receiver mode and paired the adapter to my phone (Pixel 7 Pro) which was quick and easy. I plugged a pair of headphones into the adapter and did the same test. I played video on the phone and checked for lag. No lag again. Again impressive.

For my final test I used the adapter again in transmit mode attaching it to my TV. This worked great with both the TV's headphone jack and the RCA jacks. The T-One came with the wire to convert from RCA jacks to the male stereo 1/8" plug. There is a metallic male to male stereo plug about an inch long to plug the unit directly to the headphone jack and a short cable that does the same if you don't have room for the transmitter at the TV headphone jack.

My only want for this unit would be a digital audio input so I could use both the TV speakers and the Bluetooth at the same time. That way I could use headphones and my family could listen with the TV speakers. My TV, and most TV's turn the internal speakers off when the headphone jack is activated making the output Bluetooth only with the T-One attached. That limits you to two listeners. My TV can output both internal speakers and digital audio at the same time. Not really a flaw with the T-One but something the manufacturer could think about for future products.

The sound quality transmitted by the T-One was good and I think more dependent on the headphones used to listen than the adapter.

The User Guide that came with the adapter were very good. There were clear instructions and pictures that explained how to access all of the functions of the T-One. AND the type was even big enough for my old eyes to read without my glasses. Also included is a USB A to USB C charging cord. BTW the adapter works plugged into the power cord so you don't have to worry about recharging if you don't want to.

Overall I am impressed by this tiny adapter and can recommend it for anyone who wants either a fixed or portable Bluetooth transmitter/receiver.

I will update this review if anything changes with continued use.
