Sound Card Combos, TWS & Open-Ear Earbuds: Four Audio Lines from One Shenzhen Factory

Shenzhen Tongyan Technology Co., Ltd. is an audio OEM/ODM manufacturer based in Longgang, Shenzhen, China. Rather than pushing a single hero product, we build four complete audio lines — and we build them for brands.

Line 1: Live-streaming sound card + monitoring headset, all in one

One device for streaming, gaming and calls. A built-in audio card is paired with a monitoring headset, so creators can hear themselves in real time and keep their voice steady without an extra interface box. It is the line most of our live-commerce buyers start with.

Line 2: Lapel microphone + sound card combo

Plug-and-play for creators on the move. The clip-on mic and the sound card ship as one kit, tuned for interviews, short video and outdoor shooting where a desk setup is not an option.

Line 3: TWS earbuds

True wireless earbuds with Hi-Fi sound, ANC and ENC noise cancelling, and Bluetooth 5.4 / 6.0 options. Charging cases are available with or without a battery display, so the same platform can be sold at two price points.

Line 4: Open-ear (OES / OWS) earbuds

Open-ear models sit outside the ear canal for all-day comfort — no ear pressure, and the wearer still hears the room. A good fit for sports, office and delivery use cases.
