[Review] Windows 10 supported Bluetooth's high -quality sound call "HD Voice"? ~ Demonstration test with Buffalo Headset -PC Watch

　It seems that Windows 10 supports Bluetooth high -quality calls and HD Voice.

　If you know about Bluetooth on your smartphone, you must have thought, "I'm responding."However, Windows PCs did not support much.It's been a long time, but I want to talk about this problem that I have been working on for many years in order.

　I have been playing online games since the previous century.He especially liked the competition games in the team, and used to use voice chat early to cooperate with his colleagues.Unfortunately, I have severe stiff shoulders and cannot attach over -ear -type headsets for a long time.As a result of trying various microphones and headsets, the sound of the game was sounded with an external speaker, and a one -ear -type ear -type ear headset was set for voice chat.

　However, the wired cable is poorly balanced on a lightweight headset, the cable itself is in the way, and it is not comfortable.Then, when I looked for a one -eared headset, I found a Bluetooth headset.When I use it, the sound quality is surprisingly bad.It was hard to hear the fellow speaking voice (especially when multiple people speak at the same time), and the writer's voice was also said to be difficult to hear because the sound quality was poor.This is useless.

　The cause of poor sound quality is Bluetooth specifications.There are a number of Bluetooth, which is called a profile that defines the operation and communication method, and HFP (Hands-Free Profile) is used for voice calls.HFP was lacking in power for the high -quality voice chat on a PC because the sound quality was set to be "hand -free and can be called".

　Once gave up the wireless environment, a few years later, a product that can speak high -quality calls in Bluetooth heads has begun to appear.That is the HD Voice I wrote at the beginning.

　HD Voice is HFP version 1.The specifications formulated in 6, making it possible to make a wide bandwidth voice call from the conventional HFP.Depending on the product, it may be described as MSBC, Wide Band Speech, etc., but both can be considered that high -quality calls can be used with HFP.

　Immediately, when I tried a wireless headset compatible with HD Voice to a PC, I didn't feel like the sound quality was improved.As a result of examining in various fields such as receivers and drivers, it turned out that "Windows is HFP 1.It didn't support 6. "Already HFP 1 on smartphones.The response to 6 has begun, and the Windows Phone, which was at that time, was also supported, but Windows 8, the latest OS at that time, HFP 1..It was up to 5.

　In other words, to use HD Voice on Windows, HFP 1.I had to wait for 6 to respond.However, Windows 10 did not support.Microsoft has posted a list of Bluetooth profiles supported by Windows, and sometimes I remembered it.

　And finally Windows is HFP 1.I confirmed the information of 6 support in the spring of 2017.At that time, I had no time to verify, but after that, the version was further upgraded, and in Windows 10 version 1903, HFP 1.7.It supports 1 (reference page).In other words, with the latest Windows 10, high -quality voice chat with HD Voice should be possible.
