Tea - Ultraslim Hi-Res Headphone Amp for Smartphones

Ultraslim Hi-Res Headphone Amp for Smartphones

Dear Khadas Community!

It is with great joy and anticipation that we announce the upcoming launch of our latest hi-fi audio product the ‘Tea’, an ultra-slim high-resolution headphone amplifier for smartphones. This portable amplifier features the high-performance ESS ES9281AC Pro DAC, as well as LDAC and aptX HD bluetooth audio via the Qualcomm QCC5125 chip.

Why Tea?

‘Tea’ was created to satisfy a high demand from our community for a “Portable Tone2 Pro”; many music streaming apps such as Spotify and Apple Music now have high-quality lossless music that can only be fully enjoyed when you connect a portable DAC such as the ‘Tea’ to your Android or iOS smartphone.

Freedom to Move

‘Tea’ can connect to your smartphone wirelessly via bluetooth audio with LDAC and aptX HD, or wired via a ‘USB-C to C’ or ‘USB-C to Lightning’ USB cables that are included in the box.

The ‘Tea’ DAC is thinner than an iPhone 13, but has a slight bump to accommodate the 3.5mm headphone jack, and the weight of this audio marvel is just 74 grams.

As our lives transform to become mobile, and we untether from our desks, ‘Tea’ gives you the freedom to go outdoors again; listen to your favourite lossless audio tracks whilst at the seaside, in a cafe, or just whilst out on a stroll in nature. Freedom to move in harmony with our music is like food for our collective souls.

Now Available On Indiegogo

Why only 3.5mm? Most devices from competition have balanced output as well.

Our team are also working on Tea Pro with 4.4 balanced output.

As Standard 4.4 headphone jacks comes too much in height, so we just cusotmize a full new one to delivery Ultra Slim size:

We will launch the Tea Pro slightly later on sometime next year :stuck_out_tongue_winking_eye:

Any feedback & suggestion are welcome!


Amazing!, keep rocking khadas team! :heart:


Very exciting! Any news of a desktop amp to match the T2P?

Will there be support for MQA?

How can this connect to an iPhone via LDAC when the phone itself doesn’t support that protocol?

aptx HD and LDAC for Android Phone only.

The current marketing material seems confusing. All screenshots/designs are showing the iPhone and mentioning typically Android-only features like aptX and LDAC.

So I thought this was going to add those capabilities to the iPhone via this module. That would allow iOS devices to tap into the full potential of Sony bluetooth headphones/earbuds or anyone else who may support aptX/LDAC.

Thanks this is good feedback, yes we should add some pictures of Android phones (which one though? :laughing: ).

This is a great idea. :slight_smile:

Does it support MagSafe attachment for iPhone 12/13?

Yeap :blush: it does.
