You put on your Beats Solo 3 or Solo 4 and the right earcup is completely silent. Or maybe it cuts in and out depending on how you hold your head. You've tried resetting them, re-pairing them, and testing them on multiple devices. Nothing works.
Good news: this is one of the most common and most fixable Beats repairs we see. And in almost every case, the cause is the same thing.
What Actually Causes This
The Beats Solo 3 and Solo 4 are on-ear headphones with a folding headband. That folding mechanism is convenient, but it creates a structural weak point that leads directly to this issue.
Inside the headband runs a small internal wire that carries the audio signal from the left earcup (where the electronics live) to the right earcup (where the speaker is). Every time you fold and unfold the headband, that wire flexes at the hinge points. Over time, the insulation cracks and the wire breaks internally.
The wire can look fine on the outside. The insulation stays intact even after the copper inside has snapped. This is why the problem appears without any visible damage, and why the audio sometimes cuts back in when you flex the headband a certain way.
This is a design limitation, not user error. We see it on headphones that have been carefully stored and headphones that have lived in a backpack for two years. The repeated folding motion eventually takes its toll on any Solo.
Signs It's a Wire Issue
This diagnosis fits if you're experiencing any of these:
- Right earcup produces no sound at all, even at full volume
- Audio works only in the left ear
- Right side cuts in and out when you adjust the headband or move your head
- Bending or squeezing the headband briefly restores audio to the right side
- The issue appeared gradually, not from a specific drop or impact
- Bluetooth connects fine and left side audio is clear
If audio cuts in when you flex the headband, that's the most telling sign. The broken wire is making intermittent contact at the break point, and physical movement temporarily bridges the gap.
Why It's Rarely the Speaker
When one earcup goes silent, most people assume the speaker is blown or failed. That's understandable, but it's almost never true on Beats Solo headphones. Drivers are built to last and don't typically fail without a specific impact or liquid damage event.
The internal wire runs the full length of the headband and passes through two hinge points, making it by far the most mechanically stressed component in the entire headphone. If the right side is silent on a Solo 3 or Solo 4, the wire is the right place to start.
We've repaired hundreds of Beats Solo headphones with this exact issue. In the vast majority of cases, replacing the internal wire fully restores audio to the right side.
How the Repair Works
Fixing this requires opening the headphones, routing a new wire through the headband, and soldering the connections at both ends. It's not a plug-and-swap job, which is why most people can't do it at home and why mail-in shops that don't specialize in this kind of work often turn it away.
Here's what the repair involves:
- Carefully disassemble both earcups and the headband
- Remove the damaged internal wire
- Route a replacement wire through the headband channel
- Solder the wire to the audio board in the left earcup
- Solder the wire to the speaker in the right earcup
- Reassemble, test, and verify audio quality in both channels
Soldering inside these headphones requires fine tools and practice working in a tight space. Done properly, the repair is clean and invisible from the outside, and the headphones function exactly as they did when new.
What Does It Cost
| Option | Cost | What You Get |
|---|---|---|
| GoTo Electronics internal wire repair | $55 | Wire replaced, soldered, tested, shipped back |
| Local repair shop (if they'll take it) | $60 – $100+ | Varies widely by shop |
| Beats / Apple service | Usually not offered | Out-of-warranty Solos often not repaired by Beats directly |
| Buying a replacement pair | $150 – $200+ | New pair, but the old one ends up in a landfill |
At $55, this repair makes sense if your Solo 3s or Solo 4s are otherwise in good shape. If the headband is also cracked or the earpads are falling apart, we'll let you know upfront before you commit to anything.
We Fix This for $55
Mail us your Beats Solo 3 or Solo 4 and we'll replace the internal wire and solder the connections. If we can't fix it, you don't pay.

Is It Worth Repairing
That depends on the condition of your headphones overall. Here's a simple way to think about it:
Repair makes sense if: The headband is intact, the earpads are in decent shape, and audio was clear on both sides before the issue started. A $55 repair extends the life of a $150-200 pair of headphones by several more years.
Repair may not make sense if: The headband is already cracked, the earpads are completely deteriorated, or the headphones have been through significant physical damage. In that case, the total repair cost could start to approach replacement cost.
When you send your headphones in, we do a full inspection before starting any work. If there are additional issues that affect whether the repair is worthwhile, we'll tell you before we begin.
How Mail-In Repair Works
You don't need to find a local shop or drive anywhere. Here's how the process works with GoTo Electronics:
- Submit a repair request on our site with your model and a description of the issue
- We email you a prepaid USPS shipping label
- Pack your headphones in a box with bubble wrap and drop them at any USPS location
- We receive them, inspect, repair, and test
- We ship them back to you, typically within 2-3 business days of receiving them
The prepaid label means no out-of-pocket shipping costs. You pay only for the repair itself.
Bottom Line
If your Beats Solo 3 or Solo 4 right side has gone silent, there's a very good chance it's a broken internal wire, not a failed speaker or a deeper electronics problem. This is a repairable issue, and at $55 it's significantly cheaper than buying a new pair.
If you're not sure whether the wire is the culprit, submit a repair request anyway. We'll inspect the headphones when they arrive and confirm the diagnosis before doing any work.
