Sennheiser Momentum 4 Not Turning On: Possible Causes
As you would suspect, there’s not a lot that might be wrong with a device when it fails to turn on; most of the issues are usually power-related.
When your Momentum 4 fails to turn on, there’s a likelihood that you’ve got an issue with a damaged battery on your hands. This is usually the case when you’ve been using your headphone for up to 5 years or 30,000 hours of listening, and have exceeded the charge cycle. Sometimes, your device may even manage to come on especially when the charger is plugged in, but goes off almost immediately after you cut the electric supply.
Unexpected Power Surge
The Sennheiser Momentum 4 can sometimes get affected by a power surge such that it fails to turn on immediately after. While there’s no outright solution to this, a lot of users experiencing this often recommend a factory reset to get it working again.
Faulty Multi-Function Button
The multi-function button is responsible for putting on/off the Momentum 4. When it goes bad, your device is as good as gone, unless you’re tech-savvy that’ll want to open up the device and bypass it or fix it completely.
Sennheiser Momentum 4 Not Turning On: How to Fix
The Momentum 4 is a high-end and durable smart device, as such, it wasn’t built in a manner where you can take it apart to perform fixes – useless if you’re a DIY enthusiast who’s tech savvy. Nevertheless, there are still some troubleshooting procedures you can carry out to see if your headphone has any hope of coming back on.
Do a Factory Reset
Sometimes, when your headphone becomes exposed to high voltage, its components go out of sync, as such, it may not turn on for a while. Firstly, you want to disconnect the charger (if still plugged in) and give it time. Next, you want to press and hold the power buttle for up to about 20 seconds for the device reset to trigger, and your headphone to come on again.
Aside from being the solution when your device is exposed to a power surge, it’s also the solution whenever it gets stuck in a firmware update.
Try a Different Power Source
The problem might just be a result of your battery running down when your power source is defective – either the USB-C cable and charger or the socket itself. In this case, you want to look for an alternate power source to confirm if your device is dead. Preferably, use a power bank and another working USB-C Cable before making any conclusions.
Take Apart and Change the Battery (Advanced Option)
Although not recommended if you’re not a certified client support staff for Sennheiser, it’s the only option if you purchased your headphone in a country where you can’t get in contact with a Sennheiser support staff, or can’t get a refund if the product is returned. While that’s the case, you also have to be a little bit tech-savvy and know a thing or two about electronics for this to be successful.
The built-in battery of your Sennheiser Momentum 4 is located in the left earbud. You want o take it apart and make a change of battery to see if this is the problem. Getting any third-party battery should do the trick provided it has a compatible connector with your headphone. As Sennheiser does not offer battery replacement services, this is possibly your best bet for getting your headphone to work again.
If your Momentum 4 headphone fails to turn on, you must try a factory reset and an alternative power source first before anything else. If you live in a region where you can’t return the product and/or get a refund, you may want to consider giving it to a technician for a replacement if you can’t do it yourself.
Meanwhile, the last option is usually the case when you’ve been using the device for a while. If your headphone is brand new, chances are that you won’t need a battery change. Your last problem may be a defective multifunction button which will require some technical expertise to either bypass or fix properly.
