You’ll see a few common names, usually based on the connectors and purpose. Popular types include:

• USB‑C to 3.5 mm audio adapter (often called a “dongle”) for phones, tablets, and laptops without a headphone jack.
• 3.5 mm headset splitter that separates one 4‑pole plug into mic and headphone plugs for PCs.
• 1/4‑inch (6.35 mm) to 3.5 mm converter for connecting studio gear to everyday headphones.
• 2.5 mm to 3.5 mm adapter for devices that use the smaller 2.5 mm jack.
• 3.5 mm coupler (female‑to‑female) to join two aux cables or extend length.
• Audio + charging combo adapter to listen and power your device at the same time.

Choose the name that matches your device’s port and your headphone plug.

Start by checking the ports on your tablet, then match an adapter to what you see:

1. 3.5 mm jack present: Plug your headphones directly into the round headphone port.
2. USB‑C port: Use a USB‑C to 3.5 mm audio adapter. For calling or inline controls, look for adapters that support headsets (mic + audio).
3. Small 8‑pin port: Use a 3.5 mm audio adapter designed for that specific connector style.

If you want to listen while charging, consider a 2‑in‑1 audio + charging adapter. Compatibility can vary by model and software, so it’s helpful to check the product description for headset support and review your tablet’s sound settings if audio doesn’t route right away.

Most everyday headphones use a 3.5 mm (1/8 inch) plug. You’ll also see other sizes in specific setups:

• 6.35 mm (1/4 inch): Common on amps, mixers, and instruments; use a 1/4‑to‑3.5 mm converter to connect regular headphones.
• 2.5 mm: Smaller plug sometimes used on older phones, two‑way radios, or specialty gear; a 2.5‑to‑3.5 mm adapter bridges the difference.

Beyond size, check the plug style: TRS (three contacts) is typically audio only, while TRRS (four contacts) supports headsets with a microphone. Matching both the size and plug style to your device helps avoid one‑sided audio or a non‑working mic.

Steps can vary by model, but these guidelines cover most scenarios:

1. Look for a 3.5 mm port: If your 2‑in‑1 PC has a round headphone jack, plug in directly.
2. No headphone jack? Use a USB‑C to 3.5 mm audio adapter. For calls or inline controls, pick an adapter that supports headsets (mic + audio).
3. Choose the right plug: Most headsets use a 3.5 mm TRRS plug; if your PC has separate mic and headphone inputs, a headset splitter can help.
4. Set audio device: Open system sound settings and select the connected headset for output (and input if you’re using a mic).

Results can vary by software and drivers, so a quick restart or checking audio privacy settings may be helpful.

A few quick checks can help identify what’s going on:

• Confirm it’s an audio adapter: Some USB‑C cables look similar but aren’t designed for analog audio. Many devices need an adapter with a built‑in DAC.
• Reseat connections: Fully insert the dongle and headphone plug; phone or case tolerances can cause a partial connection.
• Try another headset: This helps rule out a cable or plug issue.
• Check sound settings: Select the adapter/headset as the output device and raise volume.
• Restart your device: A fresh boot can reinitialize audio routing.
• Mic/controls: If the mic or buttons don’t work, look for TRRS/headset support in the adapter’s specs.

Compatibility can differ by device and software version, so reviewing product details before purchase can be helpful.
