KHADAS Tea Portable Headphone Amplifier DAC - Slim HiFi Mobile Amp

In this review of the KHADAS Tea portable headphone amplifier the bottom line is simple: this is a slim, phone-friendly way to get clearly better headphone sound without carrying a bulky rig. The Tea combines a dedicated ESS ES9281AC Pro DAC, a MagSafe-compatible ultra-thin body and a 3.5mm mini plug so users can enjoy lossless streaming and higher-resolution Bluetooth audio from services like Apple Music and Tidal. It is aimed at people who want true portable HiFi and convenience rather than a full desktop setup.

Key Features

• ESS ES9281AC Pro DAC: Delivers improved digital-to-analog conversion for cleaner, more accurate sound from mobile sources.
• Ultra-thin MagSafe design: At under 0.3 in thickness the Tea clamps to the back of a phone for a compact, pocketable listening solution.
• High-resolution Bluetooth: Supports LDAC up to 24-bit 96kHz plus aptX HD for better wireless fidelity with compatible phones and streams.
• Versatile format support: Plays HD, PCM, DSD and MQA formats so you can access lossless content from many streaming services.
• 1160mAh battery: Built-in battery provides up to eight hours of continuous playback without draining your phone.
• Durable materials: Lightweight aluminum and anti-fingerprint tempered glass keep the unit both sturdy and visually neat.

Who It's For

The Tea is best for mobile audiophiles who want a discreet way to extract higher-quality sound from streaming apps and phone sources, and for users who value a thin, MagSafe-compatible accessory. It fits those who often listen on the go and prefer wired headphones or want to use the Tea as a Bluetooth receiver to feed a wired headset.

It is less suitable for people who need the Tea to act as a Bluetooth transmitter to other Bluetooth headsets, since the device can only receive Bluetooth data and cannot send it. Also, anyone needing studio-grade desktop amplification or extended professional outputs should consider a larger dedicated amplifier instead.
