Fix PULSE Explore: Pairing, Audio, Mic, and Charging Help

If your PULSE Explore earbuds will not connect, have no sound, or are not picking up your voice, start by checking the connection path and updating both the earbuds and the PlayStation Link USB adapter to software version 2.0 or newer. Then work through the relevant fix below: connection checks first, fit and audio checks for one-sided sound, and the correct reset only if simpler steps fail.

For PS5, PlayStation Portal, Windows, and Mac, PULSE Explore uses PlayStation Link; phones and tablets use Bluetooth. The controls and volume behavior differ between those paths, so identifying which one you are troubleshooting matters.

What should I check before troubleshooting?

Confirm which device is supposed to provide audio, then check the software and the physical connection. PULSE Explore uses PlayStation Link for PS5, PlayStation Portal, and compatible Windows PCs and Macs. The included PlayStation Link USB adapter is paired to the earbuds out of the box; Bluetooth is the route for a phone or tablet.

1. Update both PlayStation Link devices. Sony’s troubleshooting guidance calls for the earbuds and included USB adapter to be running software version 2.0 or newer before deeper connection troubleshooting. On PS5, keep the console system software and PlayStation Link device software up to date together. Windows users can update through the PlayStation Link PC Driver.
2. Check that the earbuds have charge. Open the case with the earbuds docked to see their battery indication, or check Control Center > Accessories on PS5. Red means low or empty; rapid red blinks indicate empty.
3. Check the intended audio route. For a PS5, PC, or Mac, make sure the USB adapter is inserted and selected as the audio device where applicable. For a phone, use Bluetooth settings and select PULSE Explore.
4. Keep the earbuds in range while pairing. They search for a connection for 30 seconds, then turn off if they do not find one. Press the PlayStation Link button on either earbud to search again.

Use the least destructive recovery step that fits the symptom. A 12-second reset of each earbud preserves pairings and audio settings. Wiping pairings is a later step: it removes all PlayStation Link and Bluetooth pairings and audio settings.

How do I reconnect PULSE Explore to a PS5?

The included adapter is already paired with the earbuds, so begin by reseating it and reconnecting the buds rather than pairing them as new devices.

1. Turn on the PS5.
2. Place both earbuds in the charging case.
3. Insert the included PlayStation Link USB adapter into a USB Type-A port on the console.
4. Remove both earbuds from the case. When connected, the adapter indicator turns solid white.
5. Complete the on-screen setup tour if it appears.

If they do not reconnect, press the PlayStation Link button on either earbud to start another search. Make sure the buds are not still connected to another host and that the 30-second search window has not expired. Sony recommends the front USB ports for the best PlayStation Link connection and to reduce blockage or interference.

If the adapter is not detected, push it firmly into the port, power-cycle the earbuds, remove unused wireless adapters, and move other wireless devices away from the adapter. If sound skips or disconnects, remove USB 3.0 devices from the console while using the headset. When other wireless headsets or USB 3.0 devices must remain connected, add distance between them and the PlayStation Link adapter; a USB extension cable can help.

Why will PULSE Explore not pair with a PC or Mac?

On a compatible Windows PC or Mac with USB audio output, connect through the PlayStation Link USB adapter, then select that adapter as the active audio device. Bluetooth is not the PS Link route for PC or Mac audio in this setup.

1. Insert the adapter into the computer and confirm the earbuds and adapter are updated to version 2.0 or newer.
2. Wake the earbuds by removing them from the case, or press an earbud’s PlayStation Link button to search again.
3. On Windows, install the PlayStation Link PC Driver from the PlayStation Link system-tray icon. The driver can also be used to update firmware.
4. In the computer’s audio output settings, choose PlayStation Link Adapter.

On Windows, the PlayStation Link PC Driver provides its own quick menu, including a Disconnect option that can be used when switching between already-paired PS Link hosts. On PC and Mac, Sony says the earbuds’ volume buttons control PlayStation Link audio; the computer’s OS mixer does not control that audio volume.

How do I connect PULSE Explore to PlayStation Portal?

Pair the earbuds to Portal after completing Portal’s initial setup. Put both earbuds in the case, then hold the case’s PlayStation Link button until the indicator rapidly blinks blue (about eight seconds). Press the PlayStation Link button on Portal. When connected, the case indicator is solid blue and Portal shows the connection.

Audio can be switched between Portal and PS5 over PlayStation Link if the earbuds are paired with both hosts. To switch, hold the PlayStation Link button on an earbud for about two seconds, then press the PlayStation Link button on the target adapter. If the target host is off, the earbuds fall back to the last connected device. Only one PlayStation Link audio stream can play at a time.

Portal’s Settings > PS Link Device menu provides controls for volume, equalizer selection, microphone mute, and resetting the connected PS Link device. If the microphone fails during Remote Play or cloud streaming, also check that Portal’s own mute button is not on.

How do I pair PULSE Explore with a Bluetooth phone?

Use the case to enter Bluetooth pairing mode, then select PULSE Explore from the phone’s Bluetooth device list.

1. Turn on Bluetooth on the phone.
2. Place both earbuds in the charging case.
3. Hold the case’s PlayStation Link button until the indicator rapidly blinks blue, about eight seconds.
4. Choose PULSE Explore in the phone’s Bluetooth settings. The case indicator turns solid blue when connected.

Pairing mode lasts up to 30 seconds. If the phone does not find the earbuds in that window, hold the case button for about eight seconds to enter pairing mode again. The earbuds can be paired with up to 10 Bluetooth devices, but can connect to and play audio from only one Bluetooth device at a time.

The earbud volume rocker controls PlayStation Link audio, not Bluetooth audio. When listening over Bluetooth, adjust volume on the phone. If PlayStation Link and Bluetooth are both connected and playing, the rocker still controls only PS Link volume. Sony says simultaneous Bluetooth audio does not affect PlayStation Link audio latency.

What should I do if PULSE Explore has no sound on PS5 or PC?

First confirm that the connection is active and that the host is sending audio to the right output. On PS5, the adapter’s indicator should be solid white when connected. On a PC or Mac, the selected output should be PlayStation Link Adapter.

• Reconnect the adapter and earbuds; if the 30-second search timed out, press an earbud’s PlayStation Link button to search again.
• On Windows, install the PlayStation Link PC Driver and check that the adapter is the active output.
• On PS5, check Control Center audio output and confirm the PlayStation Link device is selected.
• Charge the earbuds if their indicator shows low or empty battery.
• Update the earbuds and adapter to software version 2.0 or newer before using the reset steps.

If the connection is active but there is still no sound, reset the earbuds as described below. If the problem persists after the non-destructive reset, consider wiping and rebuilding pairings—but note that the wipe also deletes Bluetooth pairings and audio settings.

Why is one PULSE Explore earbud silent or quieter?

A poor tip seal is a common cause of thin or uneven sound. Sony includes four ear-tip sizes, with one pair already fitted; try another size before assuming an earbud has failed.

Sony’s fit check is practical: speak aloud or stand near a loud sound source. Outside noise should be slightly muffled, music at medium volume should sound matched in both ears, and removing the buds should take slight resistance. The earbuds should not fall out. Refit each bud and try the tip size that gives a stable seal without discomfort.

If the sound remains uneven after checking fit, remove both earbuds from the case and soft-reset each one. Hold the PlayStation Link button on one earbud for at least 12 seconds, repeat on the other, then dock both buds again. This reset does not erase pairings or audio settings.

If the case indicator flashes red after a replacement earbud was installed—or two sets of earbuds and cases were mixed—the earbuds may need to be synchronized to their case. Follow the case-sync procedure below. For aftermarket foam tips, treat them as third-party accessories rather than Sony-supplied parts; fit and compatibility may vary.

Why does the volume button not work?

The volume rocker on the earbuds controls PlayStation Link audio only. For Bluetooth audio, change volume on the connected phone or tablet. During simultaneous Bluetooth and PS Link playback, the rocker still changes only the PS Link volume.

For PlayStation Link audio on PC or Mac, Sony specifies volume control from the earbuds rather than the computer’s OS mixer. On PS5, volume can be adjusted from the earbuds or the console.

How do I fix a PULSE Explore microphone or party-chat problem?

Check mute state, the selected input, and whether both earbuds are connected before treating the microphone as a hardware fault. PULSE Explore has two hidden microphones in the earbud housing and Sony describes AI-enhanced noise rejection; it does not have a boom microphone.

1. Check mute. On PS5, triple-press the PlayStation Link button on an earbud to open Sound controls in Control Center, then check the microphone setting. On Portal, open Settings > PS Link Device and make sure the mic is unmuted. Also check Portal’s physical mute button.
2. Check the input device. Confirm the console or computer is using the PlayStation Link device as its microphone input, and that the adapter indicator is solid white on PS5.
3. Check the PS5 microphone level. Go to Settings > Sound > Microphone > Adjust Microphone Level. If other people hear echo, Sony’s shared wireless-headset guidance suggests moving the Microphone Level fader two to four notches left.
4. Check fit and connection. Try a different tip size so the earbud sits correctly, reconnect or soft-reset both earbuds, and use the case sync steps if a replacement bud was installed.

There is no dedicated mute button on PULSE Explore; do not look for the separate mute control found on a different PlayStation headset. If chat still cannot hear you after checking mute, input selection, fit, and connection, use the reset ladder and then contact PlayStation Support if the issue remains.

How do I reset PULSE Explore without losing pairings?

Use the soft reset first. It resets each earbud but preserves PlayStation Link pairings, Bluetooth pairings, and audio settings.

1. Remove both earbuds from the charging case.
2. Press and hold the PlayStation Link button on one earbud for at least 12 seconds.
3. Repeat on the other earbud.
4. Dock both earbuds in the case.

If the case itself appears stuck, reset the case separately. Put both earbuds in the case, quickly press the case’s PlayStation Link button, then hold it for at least 12 seconds. Release when the indicator stops blinking. A successful case reset briefly flashes red and then green; it does not delete pairings or audio settings.

How do I erase all PULSE Explore pairings?

Use a pairing wipe only when you are ready to reconnect the earbuds to your PlayStation Link and Bluetooth devices. It deletes all PlayStation Link and Bluetooth pairings and audio settings.

1. Put both earbuds in the case.
2. Quickly press the case’s PlayStation Link button.
3. Hold the button and release when the indicator quickly blinks blue, about eight seconds.
4. While it is blinking, hold the button again for another eight seconds and release when it quickly blinks blue.

The indicator briefly blinks red when the wipe succeeds. Afterward, pair the earbuds again with the devices you use.

What does a red flashing charging case mean?

A red-flashing case can mean the earbuds need to be synchronized to that case, particularly after PlayStation Support replaces an earbud or when buds from two sets have been mixed. This synchronization procedure also wipes all pairings and audio settings.

1. Place both earbuds in the case.
2. Hold the case’s PlayStation Link button for eight seconds. The indicator cycles red, green, purple, then blue.
3. Hold the same button for another eight seconds.
4. Pair the earbuds again with PlayStation Link and/or Bluetooth, then check that they work together.

Do not confuse this procedure with the ordinary soft reset: the red-flash sync is a pairing wipe, while the two-earbud soft reset preserves pairings. If you have not replaced or mixed earbuds and the case continues flashing red, contact PlayStation Support.

How do I reset the PlayStation Link USB adapter?

Reset the adapter if its connection records appear to be the problem. This clears all PlayStation Link connections stored on that adapter, so you may need to pair devices again.

1. Turn on the PS5, PC, or Mac that will host the adapter.
2. Insert the adapter.
3. Press and hold the adapter’s PlayStation Link button for 30 seconds; Sony recommends using a timer.
4. Check that previously paired PlayStation Link devices do not automatically reconnect. If they do, the reset did not succeed.

The adapter reset is separate from the earbud and case resets. Use it only after checking the adapter’s seating, host audio output, and firmware.

How do I check charging and battery status?

Dock the earbuds and open the case to see their battery status. The indicator uses three blinks for full (green), two for medium (orange), and one for low (red); rapid red blinks mean empty. While the buds charge, the case slowly blinks orange; the indicator turns off when charging is complete.

Close the case with the earbuds docked to check the case battery. The same full, medium, low, and empty color pattern applies. Charge the case from a compatible USB Type-A port using the included USB cable. Charging in PS5 rest mode requires rest-mode USB power to be enabled.

• Sony says empty earbuds take approximately 40 minutes to charge fully.
• A 10-minute charge provides up to 1.5 hours of use, according to Sony PlayStation Support.
• An empty case takes approximately 1.5 hours to charge fully.
• Sony rates the earbuds for up to five hours of battery life, with up to an additional 10 hours from the included charging case.

These are manufacturer figures; actual listening time can vary. The case and earbud indicators show charge state, while PS5 also displays bud and case battery under Control Center > Accessories.

How do I update PULSE Explore firmware and change its settings?

On PS5, updates for the earbuds and adapter arrive with PS5 system software. If a device update is waiting, the console prompts you. You can also check Settings > Accessories > Headset for device software version and PS Link Device Software Update.

The same menu includes device naming, Reset Your PS Link Device, Take the Tour, and open-source licenses. Reset Your PS Link Device resets audio input/output settings but does not disconnect the device from PS5. These device menus are available only to the user account the device is assigned to. Keep PS5 system software and PlayStation Link device software updated together. On Windows, firmware can be updated through the PlayStation Link PC Driver without using a console.

When should I replace an earbud or add another adapter?

If a bud remains silent after checking fit, charge, software, resets, and case synchronization, PlayStation Support is Sony’s replacement path. A replacement earbud must be synchronized to its case with the red-flash procedure before normal use.

If you regularly switch between PS5 and PC, a second standalone PlayStation Link USB adapter lets you leave one connected to each host instead of unplugging the included one. Sony identifies the newer adapter as CFI-ZWA3 and an older model as CFI-ZWA2. Standalone adapters are not paired out of the box; update a CFI-ZWA2 before pairing. To pair the earbuds to another adapter, put them in the case and hold the case button until rapid blue blinking (about eight seconds), then press the adapter’s PlayStation Link button. Newer CFI-ZWA3 indicators blink or turn blue; older CFI-ZWA2 indicators blink or turn white, with the light on the button. You can pair with up to eight PlayStation Link USB adapters, but connect to only one adapter at a time; one adapter can be paired with up to eight PlayStation Link devices.

Frequently Asked Questions

Can I use PULSE Explore with a PS4?

Sony’s support material covered here documents PS5, PlayStation Portal, compatible Windows PCs and Macs, and Bluetooth mobile devices as connection targets. It does not document PULSE Explore as a PS4 wireless-headset pairing target, so do not assume the PS5 adapter procedure applies to PS4.

Can PULSE Explore connect to two phones at the same time?

You can pair the earbuds with as many as 10 Bluetooth devices, but they connect to and play audio from only one Bluetooth device at a time. To use another phone, switch to a previously paired device rather than expecting simultaneous Bluetooth playback from both.

Can I wear PULSE Explore with PlayStation VR2?

Sony says the earbuds can be used with PlayStation VR2 after they are connected to the console. Disconnect any headphones attached to the VR headset before using the earbuds.
