TC35 Pro (Eye)

iPhone users please select the Lightning version.

DAC & AMP Dongle

The dongle looks like a tail when transforming from your phone to the 3.5mm output. As long as the dongle is compact and convenient enough, it will not be considered to be awkward.

New Design 2021

The TC44B that has been on the market is a DAC & AMP dongle with only balanced outputs. This 'Eye' has been extended on the original color scheme, strengthened the golden joints at the end, and eliminated the screws. At the same time, the connecting cable* has been adjusted to be softer.

*The conductor of the connecting cable is made of silver-plated OCC, with an independent Teflon insulating layer inside, and TPE insulating layer with a good tensile strength at the outermost.

All-New Powerful Decoding Chip

It adopts the ES9281AC PRO from ESS company as the decoding chip.

Sampling rates: Support up to 32bit / 768kHz
Native DSD: Support up to DSD512
SNR: -118dB

RGB Indicator Light

In addition to indicating the On and Off status*, it can also identify different sampling rates of files with different colors, including red, blue, green, yellow, white, and magenta.

*The indicator light will flash blue, green, and red alternatively after being inserted into the phone, but it only works when the earphone is plugged in. The indicator light will be on steady when playing music.

red → PCM 44.1kHz/48kHz
blue → PCM 88kHz-384kHz
green → PCM 705kHz-768kHz
yellow → DOP (DSD over PCM)
white → DSD Native
magenta → MQA 


MQA official certification.

MQA enabled renderer that will complete the final unfold of an MQA file. The LED glows magenta to indicate that the unit is rendering an MQA stream or file. This delivers the final unfolding of the MQA file.

Auto Detect Headphone Impedance

Before use, please insert the earphone to the TC35 Pro first and then connect it to your phone. In this way, the device will automatically detect the headphone's impedance and switch between Low Gain and High Gain modes. For instance, when a high impedance is detected, it will then switch to High Gain mode to output.

Why is it called 'Eye?

In order to reduce the weight, we made the body into a waisted arc edge, which looks like an eye on the end, giving people a feeling of energetic coherence.

This is the only item to listen to lossless music across any music streaming and/or local collection. It’s so hard to have a portable DAC and this device is just awesome. Plug and play, you’re all set. The staff was awesome getting to me and one was defective. They easily did a return and gave me a working new one. Audio46 is who I’ll be mentioning for ANY music instrument needs.

Better enjoyment of music

This has improved the sound quality of the music I listen to from my iPhone. I highly recommend it.

Great Value for Money!

I am very pleased with the sonics. I use this USB-C to 3.5 mm DAC & Amp Adaptor in two locations, both with Apple equipment and my NAD Viso HP-50 headphones. In one situation I use it with my 2021 M--1 iPad Pro and in the other with my 2021 M-1 iMac computer. The sound is a bit warm yet very clear. You lose a bit of the bottom octave power of which these phones are capable. And, yes, there is a bit of a cap on ultimate SPL capability before compression sets it, but such levels are not healthy for headphone listening anyway. The unit drives these headphones quite loud enough, thank you. This unit delivers the overall best sound from these headphones I have yet heard in both situations of relatively "direct" connection to the Apple electronics. To get better sound from these headphones I would need to use something like a Benchmark DAC3 at 20 times the price, but then I still would not get full MQA decoding/rendering like this unit provides, allowing MQA recordings to really shine. Note that this device, when used with the iMac's Audio MIDI Setup app, allows upsampling/resampling of audio to 32 bit/768 MHz. While I'm usually a fan of "native" resolution, this unit combined with these headphones really shines with such extreme upsampling/resampling. The sound through this unit with this upsampling/resampling bests overall he sound from the iMac's own 3.5 mm headphone jack in all ways except ultimate SPL capability. The sound is clearer, more open, more three dimensional and tonally yet more accurate. The sound loses a bit of bottom octave power and upper bass/lower midrange warmth. But the resulting sound still has quite enough low end for complete satisfaction and the more open, three-dimensional sound with apparently greater detail more than makes up for the low-end losses.

Big surprise for this size

Superb device. It heats up a little bit, but nothing to set alarm bell ringing. You really notice its effect one in use.

Awesome Dac With A Small Cavoite

Wow this dac is great, clean sound (I don't use tidal so your mileage may vary there) and its sleek and very portable. Well built as well but so far the only problem I have with, is it sort of gets hot (A little more then I'm personally comfortable with) and I have to hold it for a bit to dissipate the heat which sounds sort of weird but it works. Not sure if this is something I should be worried about or if this dac just runs a little warm, but id defiantly keep this in mind if your like me and put this in your pocket. Otherwise great product would highly recommend if you have the cash.
