How To Fix Beats Solo 3 Wireless Right Side Not Working

To fix your Beats Solo 3 Wireless headphones when the right side stops working, you should first rule out software glitches before assuming it is a hardware failure.

Phase 1: The “Golden” Diagnostic Test

Before trying any fixes, plug the RemoteTalk (aux) cable into your headphones and connect them to your phone or computer.

• If both sides work with the cable: The speakers are fine. The issue is likely a Bluetooth glitch or a battery/firmware error. Proceed to Phase 2.

• If the right side is still dead with the cable: This confirms a hardware breakage. It is almost certainly a frayed internal wire inside the headband hinge. Proceed to Phase 3.

Phase 2: Software & Bluetooth Fixes (Try these first)

1. Perform a Factory Reset

This clears corrupted connection data that often silences one ear cup.

1. Hold down the Power button and the Volume Down (-) button simultaneously.

2. Keep holding for 10 seconds.

3. When the LED “Fuel Gauge” flashes connected lights (often red/white), release the buttons.

4. “Forget” the device in your phone’s Bluetooth settings and re-pair them as if they were new.

2. Check Audio Balance Settings

Sometimes settings accidentally shift audio to the left channel.

• iPhone: Go to Settings > Accessibility > Audio/Visual. Ensure the Balance slider is exactly in the center.

• Android: Go to Settings > Accessibility > Hearing enhancements. Check the Left/Right sound balance.

3. Update Firmware

• iPhone: Updates happen automatically when connected to iOS. Leave them connected and charging near your phone for 20 minutes.

• Android: Download the Beats app from the Google Play Store to force an update.

Phase 3: The Hardware Fix (Most Common Cause)

If the cable test failed (Phase 1), the issue is likely a broken internal wire. The Beats Solo 3 has a design flaw where the wire running through the folding hinge gets pinched and severed over time.

Option A: The DIY Fix (Requires Soldering)

• The Part: You likely need to replace the internal “5-core wire” that runs through the headband.

• The Process:

  1. Remove the ear cushion and the plastic housing on the affected side (usually involves unscrewing the hinge).

  2. Locate the severed wire inside the hinge mechanism.

  3. Desolder the old wire from the small circuit board and solder on a replacement wire.

  4. Reassemble.

Option B: Professional Repair

• If you are not comfortable soldering, this is a standard repair for electronics shops. Look for a shop that specializes in headphone repair; “internal wire replacement” is the specific service you need.

Option C: Temporary “Wiggle” Trick

• Sometimes the wire is loose but not fully severed. Try extending the headband fully or wiggling the right hinge while music is playing. If the sound cuts in and out, you have confirmed it is the hinge wire issue. Tape or keeping the band in a fixed position might offer a temporary (but ugly) fix.
