Description🌟M20 Bluetooth Transmitter Receiver – 3-in-1 Wireless Audio Adapter for Car, Speakers, Laptops & More!
Tired of old devices (like your car stereo or vintage speakers) lacking Bluetooth? The M20 solves that—turn any 3.5mm AUX-enabled gear into a wireless powerhouse, with built-in TF card playback for extra convenience. Perfect for road trips, home use, or office setups!
🔹Why The M20 Stands Out (For US Users!)
Latest Bluetooth 5.4 Chip– No lag, faster connections, and stronger stability. Stream music or take calls without annoying glitches—ideal for hands-free driving or seamless home audio.
3-in-1 Multifunctionality– Works as atransmitter(send audio from TVs/laptops to headphones),receiver(add Bluetooth to non-wireless speakers/car stereos), andTF card player(play music directly from your microSD card, up to 32GB—card not included).
20+ Hours of Long-Lasting Battery– Enjoy 20 hours of playback in receiver mode or 15 hours in transmitter mode. Low power consumption means less frequent charging, even on long road trips.
Real-Time LED Display– Instantly check battery level and working mode (transmit/receive/TF) at a glance—no guessing if it’s time to charge or which function is active.
Compact & Clip-On Design– Small (63×31×23mm) and lightweight with a built-in clip—secure it to your car visor, laptop bag, or speaker stand. Discreet enough to blend in, portable enough to take anywhere.
10-Meter Bluetooth Range– Move freely around your home or car without dropping the connection. Perfect for cooking while streaming from your phone, or sitting in the backseat with headphones.
HD Sound & Hands-Free Calls– Built-in microphone lets you take calls safely while driving. Crisp, clear audio for music, podcasts, or conference calls—no more muffled sound.
