Ultra-Thin Portable Headphone Amplifier

The Khadas Tea is an ultra-thin portable headphone amplifier designed for smartphones. It integrates a high-performance ESS ES9281AC Pro DAC and a 3.5mm headphone jack to deliver lossless audio from streaming services such as Apple Music, Tidal, and Qobuz. Its lightweight aluminium body with anti-fingerprint tempered glass measures just 7.95 mm thin and includes a magnetic function that clings to compatible phones.

For Streamers Seeking Mobile Hi-Fi

This device suits listeners who want high-resolution Bluetooth audio with LDAC and aptX HD support up to 24-bit 96 kHz without draining their phone battery. It also serves users needing a USB DAC for PCM up to 32-bit 384 kHz and native DSD 256 with MQA rendering. Buyers whose phones lack magnetic attachment or who require balanced output or higher output power for demanding headphones should look at other solutions.

Battery Life and Format Support

The built-in 1160 mAh lithium polymer battery provides up to 8 hours of continuous playback, automatically powering off after 10 minutes of inactivity to conserve charge. USB connectivity handles PCM up to 384 kHz and DSD 256 natively, while Bluetooth supports LDAC, aptX HD, and AAC up to 96 kHz. THD+N measures 0.000355% at 1 kHz into 300 ohms, ensuring clean signal reproduction within these limits.
