A headphone splitter turns one 3.5mm jack into two, or joins a separate headphone and mic plug into one. Some are short Y cables, some are switch boxes and one of the picks below is a small amplifier with four outputs. The right type depends on whether you need a mic.
The six products below come from their Amazon listing pages, where we read the jack layouts, lengths and notes. We have not used these products ourselves, and sound claims are the makers’ own.

What to Look For
| Feature | Why it matters |
|---|---|
| Plug layout | TRS (audio only) and TRRS (audio plus mic) cables are not interchangeable |
| Mic support | Some splitters list no mic use; others need a CTIA headset |
| Cable length | Short cables sit at the jack; longer ones reach a desk |
| Output type | A true splitter sends audio to both; a switch sends it to one at a time |

The 6 Best Headphone Splitters
1. UGREEN Headphone Splitter 20899
A short cable that connects a 4-pole headset to a PC or laptop that has separate audio and mic jacks. The listing mentions an aluminum alloy casing, gold-plated plugs, a nylon braided jacket and a 7.87 inch length. It notes that a CTIA-compliant TRRS cable is required for the mic to work.
Suits: a gaming headset on a PC. Strengths: a braided cable and a listed mic function. Weaknesses: the mic needs a CTIA headset. Skip it if you only want to share audio between two pairs of headphones.

2. JSAUX Headphone Splitter
A 3.5mm TRS male to two female splitter in red with a gold-plated connector and a double-braided nylon jacket. The bullets give a length of 0.9 ft and say it cannot be used with microphones, while the dimension field shows 40 inches, so confirm the length on the page.
Suits: sharing music with a friend. Strengths: a 15000-bend claim from the maker. Weaknesses: no mic use and an unclear length. Skip it if you need a mic.

3. UGREEN Headphone Splitter 60287
A 7.87 inch cable built from soft TPE with a nylon braid, a copper core and gold-plated connectors. The bullets say the headphone port suits CTIA standard headphones only, not iPhone headsets or OMTP types. The title wording and the bullets describe the plug layout in different directions, so read the connector note before you order.
Suits: a headset that has separate plugs. Strengths: a flexible cable. Weaknesses: CTIA only and a mixed description. Skip it if your headset is an OMTP type.

4. Belkin AUX Audio Cable Splitter
A white splitter with one male 3.5mm plug and two female ports, meant for sharing audio between two headphones or two mini speakers. The listing shows a lifetime warranty, a weight of 1.1 ounces and dimensions of 6.2 x 3.75 x 1.2 inches, which likely describe the packed item.
Suits: a plain two-way share. Strengths: a known brand and a long warranty. Weaknesses: no mic support is stated. Skip it if you want a braided cable.

5. LZSIG 4 Channel Headphone Amplifier
A small 1-in 4-out amplifier meant for home studios, with independent volume per channel. It lists support for four pairs of 32 to 100 ohm headphones, both 3.5mm and 6.35mm plugs, a 12V supply and a bass boost switch. The title says model LHA1 while the bullets say LHA2, so check which unit you get.
Suits: a group monitoring a session. Strengths: four outputs with separate volume. Weaknesses: it needs power and a model label conflict. Skip it if you only need two outputs.

6. Y.D.F 3.5mm Stereo Audio Switch
A passive 2-in 1-out switch box in a metal CNC case that needs no power. The listing says only one audio path is active at a time, adds a one-key mute and includes a cable. It is a selector rather than a splitter, so it does not feed two headphones together.
Suits: switching between two sources. Strengths: a compact metal case and a mute key. Weaknesses: one output at a time. Skip it if you need to share one source with two listeners.
Setup Notes
- Plug the headset into the adapter before you plug the adapter into the computer, as the UGREEN listing advises.
- Check whether your headset is CTIA or OMTP before you buy a mic splitter.
- Use a short cable at the jack and keep the weight off the port.
- Check the amplifier headphone range against your own headphones.
Mistakes to Avoid
- Buying a TRS splitter and expecting a mic to work.
- Treating a switch box as a splitter.
- Skipping the plug layout line when the title and bullets disagree.
- Assuming every headset follows the CTIA standard.
