Quality Control
Let's take our HBS Bluetooth Headset for example to explain why our quality is better than others.

Software usually means sound adjustment skill.
It is very important for sound quality.
By using the same bluetooth chipset and speaker, one producer can make a good sound, the other may make a poor sound.
We are experienced for sound adjustment for 6 years, and we are familiar with the taste of Europe and North America, so we can make an excellent sound for you.

1. CE Certificate:
At most of time, CE Certificate is a must for Europe market.
All of our HBS Bluetooth Headset have Phoenix Testlab CE Certificate.
What is more, Phoenix Testlab CE certificate is much more powerful and trustful than the China Lab certificate, especially for European customs.
