Azio USB Micro Bluetooth Adapter V4.0 EDR and aptX - BTD-V401
This USB Bluetooth adapter supports Bluetooth 4.0 and a number of profiles such as Generic Access (GAP) and Headset Protocols (HSP), ensuring it works with a wide range of devices such as mice, keyboards, and audio equipment. This model is a particularly good choice for speakers since it includes audio codec compression to ensure streaming audio sounds great from your computer and into a set of Bluetooth-enabled speakers or headphones. You get a maximum range of 33 feet with this model which makes it comparable to most other adapters on the market. This pick supports versions of Windows from XP to 10 but unfortunately doesn’t support Mac OS.
