One Playlist From Two Devices? A Piece of Cake!
The compact Bluetooth audio adapter Logitech 980-000910 allows connecting two separate devices simultaneously; for example, both a smartphone and a tablet can be connected to the adapter via Bluetooth. Now you can select a playlist, swap audio streams with one press of the adapter’s button. So you don’t have to fight with other members of your family about whose music to play. Make it fair by taking turns: mom listens to jazz from her phone, her son streams his hard rock from a tablet. In case of incoming call or messages, the music stops and resumes automatically. Please, keep in mind that to enjoy your favorite music, the stereos have to be located not farther than 50 feet from the adapter.
Good Music Is High-Quality Music!
As you might know, a reliable and high-quality connection between media devices and speaker systems is of the utmost importance. A shielded cable is considered to be the best in terms of connection. After all, the original quality is easy to ruin with poor cables, but we often blame audio equipment itself. To be sure that your stereos will deliver clean, high-quality sound without using any cables, it’s enough to purchase the Logitech Bluetooth Audio Adapter. It was tested in Logitech labs many times to ensure that all the songs would sound exactly the same as they did when recorded in a music studio.
Today, Logitech is one of the most famous brands in the world owing to their high-quality products. The leading position is explained by the development of innovative technologies that are applied to all of Logitech's products for computer navigation, games, Internet communication, home theaters, digital accessories and more. Focusing on new technologies and high quality, Logitech is constantly developing peripherals for personal computers and digital electronics that let users learn the modern world of new digital technologies.

What Is a Bluetooth Adapter?
Every year we add more and more gadgets in our life to make everyday tasks easier and more interesting. We think it's great since by using advanced technologies, we gain new experience and knowledge. Many of us have already gotten used to digital technologies. So, it's likely that we may at some point face the problem that one of our devices doesn’t feature Bluetooth to connect gadgets together. In this case, you need a Bluetooth adapter.
This compact device links digital devices together wirelessly. For example, it can turn your speaker system into a modern media station which will play your favorite music streamed from your smartphone. It also allows you to synchronize information between a PC and other mobile devices. These adapters which are also known as a wireless “dongles” generally use the latest versions of Bluetooth and are capable of transferring huge amounts of data in a matter of minutes, among other trivial things such as linking your input devices and peripherals.
In case you are interested in creating a truly wireless audio system, we also recommend paying attention to our 5 best Bluetooth headsets that can provide hands-free communication. Alternatively, you could take a quick look at the top floor speakers in order to spice up an existing Hi-Fi system.
What Features to Compare
As you already know, a Bluetooth adapter allows connecting a computer with peripherals or streaming music from your smartphone to a stereo system. Bluetooth adapters are divided by type of use, so first of all, you need to define what you want from this device. You can use it either for synchronizing peripheral devices with a PC or streaming music wirelessly from Bluetooth devices to non-Bluetooth stereo systems. For example, if you want to send photos from your smartphone to a laptop that doesn’t support Bluetooth or print some documents wirelessly, you need a USB Bluetooth adapter. Just plug the adapter into a free USB port on your laptop or PC and get the chance to exchange data with other Bluetooth devices without any cables. In addition, when you synchronize your PC with a smartphone, you also get access to your phone contacts and an option to send/receive messages. The Bluetooth protocol is supported by almost all modern phones, so in order to communicate with your computer, you only need to plug in a Bluetooth adapter and configure the connection. In case you want to stream music wirelessly from your favorite playlist or a mixtape to a non-Bluetooth audio system, then look for Bluetooth audio adapters which receive audio files of various formats without any significant loss of quality.
The next characteristic to note is adapter performance. Bluetooth adapters have a different operational range, and the higher it is, the greater the distance can be between your gadgets and the adapter that is connected to your PC or a laptop. Like any electronic device, a Bluetooth adapter requires power, so a USB Bluetooth adapter is obviously powered from a USB port. A Bluetooth audio adapter is powered by an AC adapter or built-in battery: the second option makes the adapter portable, so you can use it with any sound system, even the one in your car. The data transfer speed and device efficiency depend on the version of the Bluetooth protocol. Adapters with Bluetooth 3.0 have low power consumption and data rates up to 24 Mb/s, which is enough for streaming music or syncing with peripherals. Bluetooth 4.0 has the same data rate as Bluetooth 3.0, only the power consumption is much lower and pairing is much faster. On the other hand, the fifth version of the protocol makes the data transfer twice as fast at distances four times farther compared to the previous versions.
Another strong reason for buying is usually the presence of different features. Some Bluetooth audio devices have NFC support for rapid pairing with other NFC compatible gadgets. All you have to do in order to pair the devices is touch your smartphone. After that, music will start playing on your speakers automatically. This feature really speeds up the device pairing process: there will be no need to set a new connection with the same device if your Bluetooth adapter supports automatic pairing mode. Note that on buying a Bluetooth adapter, you also get the upgrade for your electronic devices.
Did you know?
How Do Bluetooth Adapters Work or The Evolution of Wireless Dongles
Originally designed as copy protection devices, the so-called “Dongles” or Bluetooth adapters are essential for setting up a wireless network for your desktop or laptop computer. From your wireless headset to the keyboard, mice, and gamepad, everything relies on the Bluetooth connection.
While Bluetooth adapters allow us to get rid of the cables completely and use wireless peripherals, they can also transfer data at speeds that do not differ from Wi-Fi. But how exactly are they able to do this while being so small, compared to Wi-Fi routers? You would be surprised, yet the answer is quite simple - both Bluetooth and USB technologies have come a long way since their inception back in the 90s.
Nowadays a regular Bluetooth adapter is capable of transferring all kinds of data with speeds from just a few megabytes to up to 24 Mbps and above without breaking a sweat. Meanwhile, USB versions 2.0 and 3.0 are capable of receiving and sending more than 650 megabytes per second.
Some might say that the Bluetooth connection is not really a reliable mean of data transfer and they might be right in some regard. Nevertheless, the Bluetooth 4.2 and 5.0 versions have proven that they might be even more stable than some Wi-Fi modems in terms of reliability and security of the wireless connection.
At the end of the day, by choosing wireless you can free yourself of the endless clutter called cables. Unless you are a true perfectionist that straps all the wires together the cables and power cords will always be a problem of your computer system.
How to Set Up A Wireless USB Adapter
Depending on the operating system or the device you are using there could be quite a few ways to get the Bluetooth adapter to work.
In our modern age, more often than not adapters are equipped with special pairing buttons that make it easier to connect Bluetooth devices one by one. This feature is especially handy when the adapter supports more than 5 wireless devices simultaneously.
Most of the adapter models come equipped with a pre-installed set of firmware and software that allow using them as Plug and Play devices, but sometimes this is not the case. Moreover, most of the modern PC configurations don’t have any means of reading data from installation CDs or DVDs that come together with adapters. Hence, you may need to install the drivers from the manufacturer’s website.
With driver installation out of the way, let’s take a closer look at how exactly you can tinker with the adapter settings in order to get the pesky software program to work. The majority of these devices can be adjusted by simply opening the Device Settings in your operating system menu. Besides the regular settings, you can add and remove paired devices such as controller mice, wireless headsets, microphones, and web cameras without too much of an effort. On top of that, you can set the sensitivity and data transfer quality in order to increase the bandwidth of your Bluetooth system or to remove unwanted parts of your wireless computer network.
