Yes, you can plug headphones into a guitar — but you need the right equipment

You cannot plug headphones directly into an acoustic or electric guitar and hear anything. A guitar produces a physical vibration; headphones need an electrical signal. To hear your guitar through headphones, you need a device that converts the guitar's signal into something headphones can play — either an amplifier with a headphone jack, an audio interface, or a dedicated headphone amplifier.

The path depends on what guitar you have and where you want to play. An electric guitar plugged into a small practice amp with a headphone output is the cheapest route. A USB audio interface works if you want to record or use software effects. An acoustic guitar requires a pickup or microphone first, since it has no built-in electronics.

Key Takeaways

  • Electric guitars need an amplifier or audio interface with a headphone jack to send sound to headphones; the guitar cable alone cannot do this.
  • A small practice amp with a headphone output costs $50 to $150 and is the most direct way to hear yourself play quietly.
  • A USB audio interface ($50 to $300) lets you connect headphones and also record or use effects software on a computer.
  • Acoustic guitars need a pickup installed or a microphone placed in front of them before any of these methods will work.
  • Headphone impedance (measured in ohms) matters less for modern equipment, but amplifiers rated for 32 ohms or higher work with most headphones.

Practice amps with built-in headphone jacks

A practice amplifier is the simplest solution for an electric guitar. These small amps — typically 5 to 20 watts — have a headphone jack on the back or side. You plug your guitar into the amp's input, plug headphones into the headphone jack, and turn the volume down. The amp's speaker mutes automatically when headphones are connected on most models, so you hear only through the headphones.

Common practice amps with headphone outputs include the Boss Katana-50, Fender Mustang LT25, and Vox Pathfinder 10. Prices range from $50 for basic solid-state models to $200 for amps with built-in effects. The headphone jack is usually a standard 3.5mm stereo jack (the same size as phone earbuds) or a 6.35mm jack (larger, more common on stage equipment).

The advantage here is simplicity: one cable from guitar to amp, one cable from amp to headphones, and you are done. No computer needed. The disadvantage is that you are limited to the amp's built-in sounds and effects — you cannot easily layer in software or record without additional gear.

Audio interfaces for recording and software effects

A USB audio interface is a small box that connects your guitar to a computer via USB. The interface has a guitar input on one end and headphone outputs on the other. When you plug headphones into the interface, you hear your guitar in real time, and you can also run the signal through recording software or effects plugins on your computer.

Popular entry-level interfaces include the Focusrite Scarlett Solo, PreSonus AudioBox, and Behringer U-Phoria series. These cost $50 to $150 and come with basic recording software. Mid-range interfaces ($150 to $300) often include more inputs, better preamps, and more software. You will need to install the interface's driver software on your computer before it works.

The workflow is: guitar cable into the interface's input, USB cable from the interface to your computer, headphones into the interface's headphone jack. Your computer handles the sound processing. This setup is standard for home recording, streaming, or practicing with backing tracks from your computer.

Headphone amplifiers for portable practice

A headphone amplifier is a small battery-powered or USB-powered device that sits between your guitar and your headphones. It amplifies the guitar's weak signal enough to drive headphones without needing a full amplifier or computer. These are less common than practice amps but useful if you want something portable or silent.

The Vox amPlug and similar pocket-sized headphone amps plug directly into your guitar's output jack and have a headphone jack on the other end. They run on batteries or USB power and cost $30 to $100. The trade-off is that they produce a thinner sound than a real amplifier and have limited effects, but they are genuinely pocket-sized and make no noise at all.

What you need for an acoustic guitar

Acoustic guitars have no electronics, so none of the above methods work without an additional step. You need either a pickup installed inside the guitar or a microphone placed in front of it to convert the sound into an electrical signal.

A pickup is a small device mounted inside the guitar's body or under the bridge. Once installed, the guitar has a jack on the side, and you can plug it into an amp, interface, or headphone amplifier just like an electric guitar. Pickups cost $50 to $300 installed, depending on quality. A microphone is cheaper ($20 to $100) but requires a microphone stand and an audio interface or mixer to work with headphones.

If you do not want to install a pickup, a USB audio interface with a microphone input is the next option: place a microphone in front of the acoustic guitar, plug the microphone into the interface, and plug headphones into the interface's output.

Headphone impedance and compatibility

Headphone impedance is measured in ohms and affects how loud headphones play through a given amplifier. Most modern headphones are 16 to 32 ohms, and most practice amps and interfaces are rated for 32 ohms or higher, so compatibility is rarely a problem today.

If you have very high-impedance headphones (over 100 ohms) or very sensitive in-ear monitors, check the amp or interface's headphone output rating before buying. A mismatch will not damage anything, but the volume may be too quiet or too loud to control properly. Headphone cables come in two standard sizes: 3.5mm (the size of phone earbuds) and 6.35mm (larger, more common on studio headphones). Most practice amps and interfaces have both, or you can use an adapter.

Frequently Asked Questions

Can I use regular earbuds instead of full headphones?

Yes. Earbuds are headphones — they just have a smaller driver. Any device with a headphone jack will work with earbuds, though the sound quality may be lower than with larger headphones. Make sure the jack size matches: most earbuds use 3.5mm, and most practice amps have both 3.5mm and 6.35mm jacks.

Do I need an expensive amp to hear my guitar through headphones?

No. A $50 practice amp with a headphone jack works as well as a $500 amp for this purpose. The difference is in sound quality, built-in effects, and speaker volume — none of which matter if you are only using headphones. A basic amp is fine for learning.

What if my amp does not have a headphone jack?

You can buy a headphone amplifier or audio interface separately and plug it into the amp's output, or you can replace the amp with one that has a headphone jack. A small practice amp with headphones built in costs less than adding a separate device to an older amp.

Can I use Bluetooth headphones with a guitar?

Not directly. Guitars and amps produce analog signals, not Bluetooth. You would need a Bluetooth transmitter connected to the amp or interface's headphone output, which adds cost and latency. Wired headphones are simpler and have no delay.

Will using headphones damage my guitar or amp?

No. Plugging headphones into an amp's headphone jack is designed use. The amp automatically mutes the speaker and sends the signal to the headphones instead. There is no risk of damage.
