LOUD Bluetooth Rechargeable Speaker Wireless Outdoor Stereo Bass

Bluetooth Wireless Audio Small Speaker Large Volume Black Speaker USB/TF/FM/TWS Features:

The DE413 portable BT speaker is equipped with 52mm stereo dual speakers and an 80mm super - large racetrack diaphragm. Together with three sound effect modes of surround, vocal, and bass tuned by AI algorithms, it brings a delicate and full sense of layering. The independent subwoofer passive diaphragm dives deep, delivering a powerful low - frequency impact. 

Equipped with a high - sensitivity noise - canceling microphone, it enables one - click hands - free calls with clear and loud voices, effectively filtering out ambient noise. The dust - proof silicone buttons on the top integrate functions such as power on/off, sound effect switching, and volume adjustment. The operation is intuitive and convenient, providing more peace of mind for outdoor use.

Upgraded with the BT 5.4 chip, it offers stable transmission within 10 - 15 meters. It is compatible with multiple input modes such as AUX, TF card, and USB drive, meeting various playback needs. The newly added FM radio function features a built - in antenna for fast channel searching and a wide range of channels.

 It supports the wireless dual - speaker connection function. With just one - click pairing, two DE413 speakers can form a stereo system, expanding the sound field to 360° surround. It is perfectly suitable for large - space scenarios such as living - room parties and outdoor camping, creating a shocking stereo sound effect.

The 1500mAh battery supports 6 - 12 hours of battery life, and the Type - C interface ensures convenient and fast charging. Customization services including logo, battery capacity, and color box packaging are available.
