Bose QC35 wireless headphones are over-ear Bluetooth headphones with active noise cancelling, and they remain a common choice on the used and refurbished market. This guide walks you through identifying which version you have, pairing and setting them up, understanding the noise cancelling and battery behavior, and fixing the problems owners report most often. By the end, you should know whether your pair needs a simple reset or a deeper repair.
Identify Which Bose QC35 Model You Have
Bose sold two main versions under the QuietComfort 35 name, and they are easy to confuse. The original QC35 used a cable-compatible design with a 3.5 mm input, while the QC35 II added Google Assistant or Alexa voice control, a dedicated button, and a different control layout on the earcup. Some owners also report that the QC35 II has a more useful companion app experience, though feature availability depends on your phone and region.

To check your model, look at the left earcup for a small printed label or model number near the battery compartment or the inside of the headband. Compare that label against Bose’s own support pages before assuming a feature exists. If your headphones have a mic and button labeled for a voice assistant, you likely have the II.
Quick checklist for identifying your version
- Check the model label inside the headband or on the earcup housing.
- Look for a dedicated Action or voice assistant button on the left earcup.
- Confirm whether a 3.5 mm audio port is present on the left earcup.
- Note whether the included carrying case and cable match the model in the box, if you still have them.
Pair Your Bose QC35 Wireless Headphones Step by Step
Pairing is the step most people need first, and it is usually quick. Charge the headphones before you start, since low battery can make the pairing mode behave unpredictably.
- Power the headphones off, then press and hold the power button until you hear a voice prompt indicating pairing mode.
- On your phone or laptop, open Bluetooth settings and look for the device name, usually something like “QC35” or “Bose QuietComfort 35.”
- Select the headphones. Wait for a confirmation tone or voice prompt.
- Play audio to confirm the connection. If sound comes from your phone speaker instead, check the output device in your playback settings.
- If you use the Bose Connect app, sign in and let it check for firmware updates before heavy use.
Switching between two devices
Many owners pair the headphones with a laptop and a phone at the same time. Bose headphones of this generation support multipoint in a limited way, so behavior varies by firmware. Manufacturers generally recommend disconnecting one device before connecting the other if you notice dropouts or delayed switching.
Understand Noise Cancelling and Battery Behavior
The noise cancelling on the QC35 is active, meaning the electronics generate an opposing signal to reduce steady, low-frequency sounds such as engine rumble, airplane cabin noise and air conditioning hum. It does little to block sudden sounds like voices or door slams, and it works best when the ear cups seal well around your ears.
Battery life is rated by Bose at roughly 20 hours of wireless listening, with noise cancelling on, though real results depend on volume, codec and the age of the battery. Owners who use the headphones heavily often report a noticeable drop in runtime after two or three years, which is normal lithium-ion wear rather than a fault.
Fix Common Problems
Most issues fall into a few categories. Work through them in order before assuming the hardware is damaged.
No sound or one-sided audio
Confirm the output device on your phone or computer. Then unpair the headphones from every device, power cycle them, and pair again. If one side stays silent, check whether the cable or a wired connection is interfering, since plugging in the 3.5 mm cable can sometimes mute the wireless channel.
Noise cancelling seems weak
Check fit first. Earpads that have flattened or split will leak sound. Owners frequently replace worn pads, and a step-by-step process is covered in our guide to Replacement Earpads for Bose Headphones: A Step-by-Step Guide (2026). Also make sure the noise cancelling mode is actually switched on in the app or with the physical control.
Battery drains quickly
Reset the headphones by holding the power button to power off, then charging for at least two hours. If the battery still drops fast, the cell has likely aged. Battery replacement is not a routine user repair, so contact Bose support first.
Headphones will not charge
Try a different USB cable and a known-good power source. Inspect the micro-USB port for lint or debris. Avoid forcing the connector. If the charging light never illuminates, the port or internal circuit may need service.
Tips for Getting the Most From Your QC35
Keep the headphones stored in their case when not in use, since the headband can take a set after long periods of pressure. Wipe the earpads with a dry or slightly damp cloth rather than harsh cleaners. Update firmware through the Bose app when prompted, because compatibility fixes arrive that way. If you want a broader view of how these headphones compare with other options, the overview at Bose Around Ear Wireless Headphones Review: Features and Performance covers the wider line.
Common mistakes
- Assuming a QC35 II feature exists on the original model. Voice assistant buttons are not universal across both versions.
- Leaving the headphones on the charger for days at a time, which can accelerate battery wear.
- Ignoring a warranty window. Check coverage before paying for repairs; our article on Warranty for Bose Headphones: How to Check, Claim and Protect Yours explains the process.
- Replacing earpads with mismatched generic parts that change the seal and bass response.
- Relying on noise cancelling to block sudden loud noises. It is designed for steady background sound.
Choosing Between QC35 and Newer Bose Models
The QC35 remains a sensible choice if you want proven over-ear noise cancelling and can find a well-kept used pair. Newer Bose models may offer updated codecs, different battery specifications, or changed designs, so compare specs directly before deciding. Owners comparing brands often look at Sony Versus Bose Noise Cancelling Headphones: Which Fits You Best (2026) for a broader perspective on tradeoffs.
| Feature | Original QC35 | QC35 II |
|---|---|---|
| Voice assistant button | Not included | Included |
| 3.5 mm audio input | Included | Included |
| Noise cancelling | Active | Active |
| Typical battery rating | About 20 hours | About 20 hours |
Recommended gear
A replacement pair of earpads helps restore the seal that noise cancelling depends on, and it is one of the most common upgrades owners make. Search for the exact model listed on the inside of your headband.
A protective hard case keeps the headband from deforming during travel and protects the earcups from scratches.
A short USB charging cable with a dedicated power adapter is useful if the original cable is lost or damaged.
FAQ
Are Bose QC35 wireless headphones still worth buying?
They can be, especially if you find a well-kept pair with intact earpads and a healthy battery. Check the return or warranty situation before purchasing a used unit.
How long does the battery last?
Bose rates the battery at about 20 hours with noise cancelling on. Actual runtime declines with age and heavy use.
Can I use the QC35 with a cable?
Yes, the headphones include a 3.5 mm input for wired listening, which also works when the battery is depleted, though noise cancelling requires power.
How do I reset my QC35 headphones?
Power off, unpair the headphones from all devices, and then power on and pair again. A full charge sometimes resolves stubborn connection problems.
Why does my left earcup sound quieter?
Check balance settings on your device, look for debris in the earcup, and confirm the pads are seated evenly. Persistent imbalance may indicate a hardware fault.
Can I replace the earpads myself?
Yes, replacement pads are sold for these models and are designed to snap or clip in place. Match the exact model to avoid poor fit.
Will the QC35 work with a TV or gaming console?
Wireless Bluetooth connection depends on the device supporting it. Many owners use the 3.5 mm input with a compatible adapter when Bluetooth is not available.
Conclusion
Bose QC35 wireless headphones are easiest to manage once you know which version you own. Most common problems, including weak noise cancelling and connection dropouts, respond to pad replacement, a clean reset, or a firmware update. For battery or port failures, check warranty options first and consult Bose support before attempting internal repairs.
