Switch Bluetooth Audio Adapter

[20 Hz - 20kHz] I use the Aluratek ABC02F Universal Bluetooth Audio Receiver and Transmitter connected to the Optical Audio output on my Sony TV. It pairs with a set of Sony Bluetooth earbuds to provide a separate channel for audio for my aging ears while the TV's audio continues to function independently for the rest of the family. The optical connection to the TV was simple and the ABC02F paired quickly and easily to the Sony Earbuds. The ABC02F is plugged into a USB port on the TV and is always on so the earbuds are reconnected within the time it takes to remove them from their charger/case and insert them into the ear.

[7.7 x 4.7 x 3"] I have always had great luck with and have been very satisfied with Logitech products. This Bluetooth Audio Adapter was very easy to set up and allowed me to choose multiple audio connections - depending on the device you want to connect to (RCA or 3.5mm connections). I would recommend this device to anyone wanting to upgrade an older audio system or speakers to Bluetooth connectivity.

[67 mm] Similar to other adapter rings it allows me to switch filters to different lenses

[UHS-I] We use this as a last precaution against memory card failure, if something happens to the card/adapter we just switch this out to another adapter

I use it in a small bluetooth speaker. Amazing. Durable, large capacity for audio,

[microSDXC] I use it in a small bluetooth speaker. Amazing. Durable, large capacity for audio,

[4.0] Very useful adapter for laptop w/o Bluetooth. Easy to install, and works great.

[200 to 8000] its comfortable for smaller hands (i got the smaller size) clicking is very quiet. i really like the on and off switch as well. i don't have to reconnect to Bluetooth every time upon startup. it's fast and extremely easy to set up. a good purchase if you're on desktop or laptop often

[Scissor] [This review was collected as part of a promotion.] The Bluetooth set up was very easy. I love the little switch on the back of the keyboard to turn it off. The keys aren't completely silent but they are quiet. It's easy to get comfortable with the compact design. It fits perfectly in my laptop bag with room to spare. The pink color really pops with my desk & decor.

[6 Months] This is the fourth one of these that I've used because the design is perfect for my needs. The first two were wi-fi but this and the third one are bluetooth. I use #3 with my Dell laptop and #4 with a MacBook Pro. They flatten out to switch them off which saves the battery and store easily in a laptop case or even temporarily in a shirt pocket. The two AAA alkaline cells last about four months with daily use, even though I sometimes forget to switch them off.
