我们几乎想当然地认为每台计算机都配备了蓝牙技术(Bluetooth technology)。毕竟，每台笔记本电脑、智能手机、游戏机，甚至一些咖啡机都有蓝牙！
然而，如果你有一台台式电脑，它很可能没有开箱即用的蓝牙。您必须使用PCIe附加卡添加它，或者更方便的是，使用USB 蓝牙(USB Bluetooth)适配器或“加密狗”。
虽然这些通常很便宜，但很容易购买放入垃圾箱（或返回亚马逊(Amazon)）的加密狗，因为它不适合用途。我们收集了一些最佳示例，以便您在第一时间购买正确的加密狗。
在蓝牙适配器(Bluetooth Adapter)中寻找什么
USB蓝牙(USB Bluetooth)加密狗始终必须平衡尺寸与范围。微型(Micro)适配器有一个小的内部天线，几乎与USB端口齐平。对于想要在办公桌上使用游戏控制器或无线蓝牙(Bluetooth)耳机的人来说，它们是一个很好的解决方案。
如果您想在更远的范围内使用蓝牙(Bluetooth)，则需要考虑使用具有大天线的型号。这会扩大信号范围，并为您提供一些调整信号方向强度的余地。
至于技术规格，选择支持最新蓝牙标准(Bluetooth Standard)的加密狗几乎总是正确的选择。在撰写本文时，那是蓝牙 5.2(Bluetooth 5.2)。较新版本的蓝牙(Bluetooth)增加了带宽、降低了功耗、提供了更少的延迟，并且可以同时处理更多的设备。
大多数现代计算机都有几个USB 2.0端口，因此您不必为蓝牙(Bluetooth)适配器牺牲一个USB 3端口。最重要的是，事实证明USB 3.0会导致无线电干扰，特别是导致蓝牙问题(causes issues with Bluetooth)，因此您不会看到很多USB 3加密狗。新的蓝牙(New Bluetooth)标准向后兼容旧标准。
EDR或增强数据速率(Enhanced Data Rate)很有帮助，因为它可以通过更好的数据传输速率获得更高质量的音频。您还将体验到更少的音频干扰和卡顿。
我们在这里专注于支持Windows的适配器，但其中许多产品也可以在 macOS、Ubuntu Linux等平台上运行。因此，请务必在购买前仔细检查兼容性。

7 Best USB Bluetooth Adapters/Dongles for Windows PC
We almost tаke it for granted thаt every cоmputеr comes with Bluetooth technology. After all, every laptop, smartphone, game console, and even some coffee makers have Bluetooth!
Yet, if you have a desktop computer, the odds are it doesn’t have Bluetooth out of the box. You’ll have to add it using a PCIe add-in card or, much more conveniently, a USB Bluetooth adapter or “dongle.”
While these are generally inexpensive, it’s easy to buy a dongle that goes in the trash (or returned to Amazon) because it’s not fit for purpose. We’ve rounded up some of the best examples so you can buy the correct dongle the first time.
What to Look For in a Bluetooth Adapter
A USB Bluetooth dongle always has to balance size against range. Micro adapters have a small internal antenna and sit almost flush against the USB port. They are an excellent solution for people who want to use a game controller or wireless Bluetooth headphones at their desks.
If you want to use Bluetooth at longer ranges, you’ll want to consider using a model that has a large antenna. This boosts the signal range and gives you some leeway to adjust the directional strength of the signal.
As for technical specifications, it’s almost always the right move to pick a dongle that supports the latest Bluetooth Standard. At the time of writing, that’s Bluetooth 5.2. Newer versions of Bluetooth increase bandwidth, reduce power consumption, offer less latency, and can handle more devices simultaneously.
Most modern computers have a few USB 2.0 ports, so you don’t have to sacrifice a USB 3 port for your Bluetooth adapter. On top of this, it turns out that USB 3.0 can cause radio interference that specifically causes issues with Bluetooth, so you won’t see many USB 3 dongles. New Bluetooth standards are backward compatible with older standards.
EDR or Enhanced Data Rate is helpful since it allows for higher-quality audio thanks to much better data transfer rates. You’ll also experience less interference and stutter in audio.
We’re focusing on adapters that support Windows here, but many of these products will also work on macOS, Ubuntu Linux, and more. So be sure to double-check compatibility before making a purchase.
Pros
- Affordable price
- Up-to-date BT features
- Amazing range
Cons
- Only works with Windows officially
- Requires a long-range Bluetooth receiver device for the best results
It’s easy to mistake the ZEXMTE Bluetooth dongle for a Wi-Fi adapter with its large external antenna. However, this high-gain antenna is crucial for achieving the theoretical maximum range of Bluetooth. Its Bluetooth 5.0+ EDR technology can work as far as 328 feet (100M), which is ten times as far as Bluetooth 4.0.
That makes it perfect for situations where you want to use a wireless speaker that’s far away from your computer. The ZEXMTE isn’t just useful for desktop computer users since it will extend the Bluetooth range of any laptop compared to the typical internal Bluetooth radio.
Unfortunately, since communication goes both ways, your target Bluetooth device must be a “Class 1” device to benefit from this dongle’s extended range. This dongle is only supported in Windows, as far back as Windows 7.
2. Best for Upgrading Older Systems: TP-Link UB400
Pros
- Very inexpensive
- Small, low-profile
- EDR and A2DP functionality
- Windows XP support
Cons
- Bluetooth 4.0
- Windows-only
The UB400 is an inexpensive Bluetooth wireless adapter, offering an older level of technology. This is only a Bluetooth 4.0 dongle using USB 2.0 connectivity, but it provides A2DP high-quality audio streaming and EDR. As long as the 65-foot (20M) range is good enough for you, it’s a fantastic nano-receiver.
Best of all, it has drivers for Windows versions as far back as Windows XP. So if you have an older system that you want to re-use as a jukebox or you want to add wireless peripherals, the UB400 is a bargain. Just bear in mind that it’s only compatible with Windows.
Pros
- Bluetooth 5.0 Features in a nano package
- ASUS is a trusted brand with excellent driver support
Cons
- Slightly more expensive than the competition
The BT500 packs Bluetooth 5.0 technology into a nano form factor at a very reasonable price. So you get all the bandwidth and range benefits of the current generation of Bluetooth and BLE (Bluetooth Low Energy) for communication with battery-powered devices such as console controllers.
It’s a few dollars more expensive than other comparable Bluetooth dongles, but ASUS is one of the most trusted names in computer hardware, so you have some peace of mind that there will be driver updates for some time and that those drivers will be stable.
Pros
- Dedicated low-lag Bluetooth audio
- Truly plug-and-play. No drivers are needed
- Perfect for movies, games, or glitch-free audio
Cons
- Costs more than the average dongle
- Can only be used for audio, not keyboards or other Bluetooth gadgets
Bluetooth is widely used for wireless audio, but one major weakness of the technology is latency. You may have noticed that audio lags behind what’s happening on-screen when watching a movie or playing a game.
This is one of the reasons gaming headsets for consoles like Xbox use proprietary wireless standards to offer virtually lagless audio. Unfortunately, this usually means you can only use specific official headsets rather than any Bluetooth headset of your choice. If you’re a PC gamer, things are even worse since Bluetooth is your only choice, and the amount of lag can vary wildly depending on the headset and adapter combination.
That’s where the Avnatree DG80 comes in. This audio-only dongle doesn’t present to the operating system as a Bluetooth adapter. Instead, it’s a USB audio device with an independent Bluetooth system. The DG80 connects to your headset independently and offers a dedicated, low-lag audio connection.
It not only works with PC and Mac but also with gaming consoles that support USB audio devices. While you can’t use this for anything other than audio, it will almost always be the superior audio solution for wireless headsets.
5. Best for Long-range Audio: Avantree Leaf
Pros
- Long-range, low-latency audio that works with anything that supports USB audio devices
Cons
- Only works as an audio adapter, no other Bluetooth connectivity
If you skipped straight to this review, read the above for the DG80 first because just about everything we had to say about that adapter applies to the Leaf, another audio-only dongle from Avantree.
It has the same features and approach to doing Bluetooth audio right, such as AptX support, and is completely plug-and-play. You can use it with many devices for audio, and it does not present as a Bluetooth adapter but as a USB audio interface.
The difference between the Leaf and the DG80 is that the Leaf is a Class 1 device with an extended transmission range. It’s rated up to 60 feet (20M) without dropping quality or latency. This means you can play your Bluetooth speakers anywhere within that range, assuming nothing is blocking the signal, and you can comfortably sit far away from your PC or console while gaming with a headset.
Pros
- Widely compatible and reliable.
Cons
- Only Bluetooth version 4.0.
The Kinivo BTD-400 is one of the most popular Bluetooth dongles on Amazon, with nearly 11 000 reviews and an average rating of 4.5 stars. It’s not hard to see why either. It may only be a Bluetooth 4.0 device, but its strength lies in its broad compatibility.
Not only will the BTD-400 work with Windows versions back to Windows XP, but you can also use it with Linux, Raspberry Pi, and macOS systems. The BTD-400 is based on the venerable and widely supported Broadcom chipset.
If you absolutely must have Bluetooth 5.0+, then the BTD-500 is only a little more expensive but just as compatible.
Pros
- Supports a robust number of Bluetooth Profiles
- Supports Windows 7 and Vista
- Exceptionally reliable according to customers
Cons
- Only Bluetooth version 4.0
- No BLE support on Vista or Windows 7
We take Bluetooth support in operating systems like Windows 10 for granted these days, but it hasn’t been a standard for all that long. Windows Vista and 7, which is now out of official support, don’t have the robust Bluetooth support of newer versions of Windows.
Using the driver provided by Plugable, this dongle adds support for all of the classic Bluetooth Profiles to Vista and Windows 7. However, there is no support for Bluetooth Low Energy, which is restricted to Windows 8 and up.
