How long does the battery last on a single charge?

The Sennheiser Momentum 3 delivers approximately 17 hours with Bluetooth and noise cancellation active. A quick 10-minute charge gives you about two hours of listening time, perfect for those rushed mornings.

Can I use these headphones with a cable when the battery dies?

Yes. The included 3.5mm audio cable lets you continue listening even with a dead battery. This wired mode works passively without power, and sound quality remains excellent.

Are these headphones good for phone calls and video meetings?

Yes, they handle voice calls well. The built-in microphones pick up your voice clearly, and noise cancellation reduces background noise during calls. They're more than adequate for phone conversations, Zoom meetings, and video calls.

Do these headphones work well for working out or running?

Not really. They're fairly substantial in size and weight, and aren't sweat-resistant or waterproof. For gym use or running, sports-oriented earbuds would be better. However, they work fine for walking, light exercise, or casual outdoor activities.

How does the noise cancellation compare to Sony or Bose headphones?

The noise cancellation is effective for airplane engines and background hum, though slightly less aggressive than Sony WH-1000XM or Bose QuietComfort models. Many users prefer this balanced approach since extremely strong ANC can feel uncomfortable. You get excellent sound quality alongside good noise cancellation.
