A system in a box
The TOPPING MX3s is a comprehensive audio solution that combines a DAC, headphone amplifier, and power amplifier. With this versatile system, you can experience your favorite music and movies through a variety of devices, including in-ear monitors, full-sized headphones, and even a 2.1 speaker system.
24-bit Bluetooth
Stream hi-def music from all of your devices, such as tablets, phones, and laptops. The 24-bit Bluetooth chip supports AAC, SBC, aptX, aptX HD, and aptX Adaptive, achieving lossless transmission with distortion below 0.001%.
Subwoofer output
Don’t just hear the music—feel it with a subwoofer. Connect a subwoofer to the MX3s for a full 2.1-channel premium entertainment experience.
Two-step gain
The MX3s plays well with headphones and speakers of all impedances. Choose high gain or low gain, whether you’re listening to a pair of headphones through the headphone output or a pair of speakers + subwoofer.
On-the-fly EQ adjustments
Grab your remote and make quick adjustments to the bass and treble. Movie night? Increase the treble to bring out that too-subtle dialogue. House party? Bump the bass by a full 10 decibels.
Auto off
A true set-it-and-forget-it unit, the MX3s will automatically go into standby mode sixty seconds after you stop playing music.
