Brand History
16 years ago, the head of the company began researching electronic products and founded the brand 12 years ago. The meaning of this brand includes two parts. X is the first letter of the small Pinyin, and Dobo is the name and surname of the founder of the company. This means that everyone can start from a young age and create their own work and life. As long as we persist in doing what we want to do, ultimately everyone can achieve a proud result.

Product feature description:

The 3.5mm AUX connector allows the use of television and non Bluetooth devices. Elegant design, comfortable to wear. Therefore, the 1px7 portable Bluetooth speaker is the best choice for listening to music from morning to night, making it the perfect companion for your long-distance travel!

• Waterproof and dustproof IPX7

The design and supply of XDOBO Bluetooth speakers are completely waterproof, providing the highest level of IPX7 intrusion protection. Some competitors may only offer IPX7 grades that are splash proof or light rain proof, rather than waterproof. This allows you to enjoy it in different situations such as seaside, rainy, or showering. No matter where you go, no matter what you do, you can enjoy beautiful music!

• True stereo speakers

Pair two 20W XDOBO speakers and use Bluetooth to achieve true wireless stereo playback for separate left and right channels. Simply control the true wireless stereo master device, and then use 3D digital surround sound combined with DSP technology and dual subwoofer stereo to synchronously play audio on both devices, achieving perfect output in any environment in your home.

• New generation Bluetooth speaker 5.0

The advanced Bluetooth 5.0 technology has faster and more stable signal transmission, clearer sound quality, and lower power consumption. The wireless speaker has a range of approximately 18 meters and is compatible with iPhone, iPad, iPod, Samsung, and HTC.
