Product Details
- 【3 switch positions, 4 tuning styles】To meet the needs of users with different listening styles, the ST1 Pro uses electronic crossover technology to design a three-position tuning switch that enables four tuning styles to be switched to meet the needs of different listening sensations and different scenarios.
- 【The 4th generation dual magnet dynamic driver】The 4th generation 10mm dual magnet dynamic driver is specially developed to perform better than previous generations. Strong N52 magnet, together with nanotech composite diaphragm gives excellent resolution, a balanced across frequency spectrum and precise stereo imaging.
- 【Semi-open back air vent design】ST1 Pro adopts a semi-open back design, which helps to achieve air pressure balance within the inner acoustics chamber, effectively relieving pressure on the eardrum. This allows full music enjoyment without discomfort. In addition, this unique design gives a livelier and airier sound to your favorite music.
- 【Quality cable】ST1 Pro With audiophile-grade 4 core silver plated cable. Fine, full-bodied and rounded sound with full-resolution.
- 【Ergonomically designed for your ears】Based on the human ears, the external shell is shaped for long-wearing without fatigue or irritation. Secure, over-the-ear design ensures earphones stay in place for unmatched comfort and sound isolation.

Ways to pay
Why customers trust Vantage Goods
Every order comes with real packing proof.
Trust should not rest on promises alone. That is why we record a packing video for every single order we send out.
The video shows your exact product, its condition and how it is packed, and we send it to the WhatsApp number on your order.
You see what is in the box before it reaches you, so you are not buying on blind trust. You are buying with video proof.
- A packing video recorded for every order
- Your exact product shown before it is sealed
- Condition and packing clearly visible in the video
- Video sent to the WhatsApp number on your order
- Device fit checked against your order before dispatch
Why we don't offer open-box delivery
Open-box delivery is a service that very large marketplaces like Amazon run through their own delivery networks. Courier partners generally do not offer it to independent stores like ours.
Rather than promise something we cannot guarantee, we chose a more transparent option: a packing video for every order.
It lets you check your product and how it was packed before the parcel arrives.
- Real packing video
- Sent on WhatsApp
- Checked before dispatch
- 7-day returns

Questions
Before you buy
When will it arrive?
Standard delivery takes 7 to 12 business days. It is free on US orders over $29; smaller orders pay a flat $5.
What comes in the box?
The package list in this listing's description shows exactly what ships, including the plugs and ear tips.
Will it work with my phone?
A 3.5mm plug needs a headphone jack. A USB-C plug works with phones, tablets and laptops whose USB-C port supports USB audio. 2.5mm and 4.4mm plugs are balanced outputs for music players, DACs and amplifiers. The TE Pro and Black Pearl DACs add 3.5mm and 4.4mm outputs to a USB-C device.
Can I replace the cable?
Yes. TRN cables are detachable: most use 2-pin connectors, the TA1 uses MMCX. The two do not fit each other.
What if it arrives damaged or does not work?
Tell us within 48 hours of delivery and we will arrange a replacement or refund. Other returns are accepted within 7 days of delivery under our returns policy.
Is there a warranty?
Cover after the first 48 hours depends on TRN's terms for the product. We help you make the claim with TRN. Our Warranty, Authenticity and Limits page has the details.
Is this a genuine TRN product?
Yes. It is TRN's own product, and we are an independent reseller, not TRN itself. If anything you receive does not look original, contact us within 7 days of delivery for a full refund.
Is the price final?
Yes. There are no customs duties or other charges on delivery. Orders under $29 pay $5 shipping and orders of $29 or more ship free. Instant Ship, where offered, is added as its own line in the cart.
