MAS CARNEY TH9
The built-in DAC chip and 120Ω impedance deliver clear, reliable audio directly through the USB-C port, bypassing the need for a headphone jack. The semi-in-ear design eliminates silicone tips for all-day pressure-free comfort, while the inline controls and microphone add practical functionality for calls. These are best for students and commuters needing an affordable, no-fuss wired option for online classes and casual listening on modern smartphones.
