Medical-Grade High-Transparency PC Material with Aluminum Alloy Cavity

TANCHJIM ONE is crafted with Medical-Grade High-Transparency PC Material and an Aluminum Alloy Cavity. The high-transparency shell combined with the aluminum alloy rear cavity enhances the overall aesthetics of the product, giving it a minimalist, fresh, and compact appearance. The rounded design at the edges further improves the tactile experience and adds a touch of softness to the product. Tailored for precise low-frequency control, allowing the bass to dive deeper, be more elastic, and not just a mere vibration of the entire sound field. Instead, it delivers a clear outline and pulsating sensation of the bass.

Flagship Dynamic Driver Unit

Featuring a combination of metal ball-tops and PU & PEEK composite material for the diaphragm, the earphones achieve a wider dynamic range and significantly reduce distortion, resulting in more solid imaging and positioning. Every piece of music is presented like a captivating story, creating an immersive audio experience.

Ultra-Smooth Surface Design

The extremely smooth surface design minimizes high-frequency acoustic damping on the inner walls of the sound cavity, effectively controlling sound scattering, improving sound transmission efficiency, and enhancing acoustic performance. This results in a more supple and linear rendition of the extreme high frequencies, with exceptional extension, clarity, and smoothness.

High-Performance Audio Decoder for DSP Tuning

TANCHJIM has optimized the professional tuning with consideration for market preferences. The ONE-DSP version utilizes a high-performance audio decoder for DSP tuning, featuring a smooth perception of the extreme high frequencies, well-controlled midrange, and enhanced low-frequency extension, all in line with TANCHJIM's target frequency response curve. Both the version with and without a microphone are designed to closely match the HARMAN 2019 target frequency response curve, comparable to flagship-level objective standards. The balanced three-frequency response is tuned to satisfy the majority of listeners' preferences, ensuring both monitoring accuracy and an enjoyable, long-lasting listening experience.

Ergonomic Wearing Design

Angled Straight-In Wearing Style, Coupled with Angled Sound Outlet, Ergonomic Design, and Precision Ear Canal Fit for Easy Plug-and-Play Convenience; while the Over-the-Ear Wearing Style is more suitable for audiophiles' wearing habits, with an ergonomic design that precisely matches the contour of the ear. The comfortable listening experience is beyond words.

Impeccable cable and microphone quality

With a 0.78mm detachable cable design, the cable is flexible, effectively preventing tangling and resisting pulling forces. The cable sheath is made of inert material, ensuring a smooth texture that doesn't knot easily. Just a shake, and it unravels effortlessly, while also improving the current transmission rate. The high-definition call microphone supports in-line control, fully meeting your daily needs.

Built-in High-Performance DSP Audio Decoding Chip

The chip inside the TYPE-C connector of the earphone features two channels of 24-bit high-performance DAC supporting 44.1kHz, 48kHz, and 96kHz sampling rate output. It includes a high-performance miniature earphone amplifier and a low-noise microphone circuit. The microphone recording even adopts a 24-bit 96kHz high-spec input. In addition, the rational application of DSP technology contributes to the exceptional audio quality experience of ONE-DSP. (Currently, ONE-DSP is being integrated with the TANCHJIM APP for tuning. Once the integration is complete, it will be available for tuning via the APP, just like ZERO-DSP.)

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.

We cannot ship to addresses that are "PO boxes or APO/FPO".

*Note: Generally, we can only do Selected Shipping to India and Russia. We can only do Express Shipping to Africa, Argentina, Hawaii, Kuwait, Mauritius, Montenegro and Sri Lanka, to name a few.
This may be subjected to changes due to unpredictable issues such as Covid, war, and etc.

How much does shipping cost?

We have two shipping methods - Standard Shipping and Express Shipping.

Standard Shipping is free for most countries, while Express Shipping is 15-35USD depending on your country. If your order is over 270USD, Express Shipping is free*. 

*This applies for most countries. However, large items such as headphones and desktop DAC/AMPs (e.g. HarmonicDyne G200, MUSICIAN MDP-2, and etc.) are excluded.

Shipping fees exclude import taxes or processing fees that may be applicable for your country. Linsoul is not responsible for such fees. Should you refuse to pay the tax/customs fees, shipping fees will still be deducted from the amount paid for the two-way freight charges. The cost of the freight charges may be more than the amount reflected on your order due to tax and other miscellaneous fees.

Some parcels claimed to be “returned to the seller” may be destroyed by the post office or customs officers when buyers refuse to accept their parcels or fail to pay for their taxes. No refund will be processed for such cases.

Standard Shipping via YunExpress is a tax-inclusive option for some countries. However, Linsoul will not be responsible for additional administrative or handling fees charged by your local courier company or customs. Please kindly check this with your local customs.

For certain remote areas, there may be additional charges via Express Shipping. We will contact you if there is a need to make additional payments. 
Please contact us before placing an order, should you have any queries regarding shipping.  

How long does it take to receive the order after it is placed?

For in-stock products, your order will be shipped within 3 working days. You may check with our staff regarding the in-stock status of any products. 

Customized items will take a longer time. Please contact our staff for more information.

On normal non-sale days, once your parcel has been shipped out:

  • For Standard Shipping, it takes about 2-4 weeks for items to be delivered after shipping out. For some countries, it might take up to 2-3 months, depending on your country, its customs and other factors.* The duration for transit is something beyond our control. Linsoul will not be making refunds for such cases. Please consider an upgrade to Express Shipping or keep the waiting time in mind.
  • For Express Shipping, it takes about 3-7 days for items to be delivered after shipping out.

*Note: Timings might be affected due to festive seasons or other unforeseen circumstances

What happens if the parcel has been shipped but not delivered?
  1. First, kindly contact your local courier using the local tracking number.

    For orders below $50USD, you may either opt for a one-time reshipment of parcel OR a full refund of the amount paid in cash via PayPal/Credit/Debit card.
    For orders above $50USD, we will only process a 50% refund of your order paid in cash via PayPal/Credit/Debit card. Should there be any concern about Standard Shipping, you are encouraged to opt for DHL Express Shipping instead.

    • Wrong address or phone number provided by recipient
    • Recipient was uncontactable when courier company contacted

    • Lost or damaged parcel because recipient opted for “no-signature delivery”

Customers have to bear any form of custom/import/processing fees that are applicable for your parcel.
