Self-developed adaptive clock system technology
Self-developed adaptive clock system technology, built-in 4 independent ultra-low jitter audio crystal oscillators, equipped with a femtosecond-level local clock system for the USB part, the standard version of the crystal oscillator is AS-318B, and the high version is CCHD- 957. SDA-6 supports external clock input, among which USB supports 10M clock input, and other interfaces support WCK input. In USB mode, it also supports 50 and 75-ohm switchable input impedance.
High-performance DAC Decoder
High-performance digital-analog hybrid phase-locked loop, excellent clock synchronization recovery technology, can greatly filter the secondary PLL of external digital input jitter.
Rich input and output interfaces
It adopts 4 channels of fully balanced and full DC discrete circuit output; among them, the high-end version adopts non-loop negative feedback output. It has a wealth of input and output interfaces, including standard USB2.0 input interface, SPDIF and BNC coaxial and AES balanced input, HDMI-I2S input interface, analog output including XLR balanced output and RCA single-ended output; all interfaces support DSD input.
Multi-input channel isolation technology
Large-scale FPGA for digital audio signal processing, self-developed second-generation algorithm, original multi-input channel isolation technology, to ensure the purity of each input signal.
Adopts the latest AK4499 DAC chip
Built-in 40 watt custom O-type transformer, output 4 independent power supply windings, up to 20 groups of distributed voltage stabilized circuits; The DAC chip adopts the latest AK4499 released by AKM in 2019; DSD adopts the native direct solution mode. The DSD digital stream does not pass through the internal digital filter and works in the NOS mode, which is fully in line with the design concept of HQPlayer.

Shipping FAQ
Which countries do you ship to?
We are generally able to ship to most countries via Express Shipping, and many countries via Standard Shipping. You may clarify this with our team to check whether Standard Shipping is available to your country.

These are great, nice sound and they fit just right. The cable isn't perfect but it does the job. Also the ear things are nice. Also these can withstand a washing machine although the wiring might come off...
Absolutely thrilled with my 7HZ Legato in-ear monitors! The powerful bass and immersive soundstage create a truly captivating listening experience. The vocals are clear and the overall sound quality is impressive. The build quality is top-notch, with the CNC aviation-grade aluminum shells exuding durability and style. The included 7 pairs of ear tips ensure a comfortable fit for extended listening sessions. Highly recommended!
I ordered two units of the TC35i to use concurrently for convenience so I don't have to keep swapping the adapter around. After five months of ordinary usage, the adhesive holding the plate to the shell gave way and the unit just fell apart while plugging it in. The internals get pushed out doing so, damaging the connection port and the ribbon cable.
I contacted customer service and they just told me to glue it together, that's it. Poor product quality and terrible customer service that seemed to want nothing to do with me once the product delivered.
Now I'm left with two broken adapters and a disappointing impression of this company.

Natural tuning with forward mids and great bass. It sounds more detailed and better than many more expensive iems out there. People who claim that all-BA iems cannot produce good bass should get this set. They may change their thinking. Last thing to add, the faceplate design is much more beautiful in reality.
It seem I am the only one who purchased this pair of IEMS, let me tell you something after 100 hours burn and the perfect tips (foam for me).
The sound is sublime, the right amount of bass and kick in the drums, voices forward, maybe to energetic in the upper mids but if you're using a warm signature DAC, you'll be fine and the highs fantastic, the percussions very rich and detailed.
The soundstage is kinda narrow but you can pinpoint the instruments.
Note: I use the Luxury and Precision W2 DAC (with some tweaks to fit my needs) and the 4.4 mm output with upgraded cable.
Cable seems okay quality, its very nice and flexible but the twised wire is extremely uncomfortable on your ears, i dont reccomend this

The Tripowin Grace adopts special braiding technique. It looks sophisticated but also elegant and neat in look. It feels soft and easily be stored without any tangling.
