ACCENTUM Open - Not "just" earbuds -- a lifehack.

Got high standards? We hear you. Whether it's party time, me time, hustling, or chilling, Sennheiser's ACCENTUM Open wireless earbuds have your back with incredible music. Why settle for less? With their open wireless design, you don't have to choose between your tunes and the world around you. Enjoy up to 28 hours of playtime*, stay connected and experience fantastic sound with ultimate comfort.

*Up to 28 hours battery every full charge.

 

Tuned for superior sound & extra dopamine. - Simply great sound, every time.

Treat your ears to the thrill of Sennheiser-tuned sound. With powerful 11 mm dynamic transducers and SBC and AAC audio codec support, ACCENTUM Open earbuds deliver rich, detailed sound.

 

With open design -- perfect for eavesdropping? Your sounds? Or your world? …why choose?

Flexible, reliable, and always in sync with your life. The open earbud design keeps you tuned into your surroundings - whether you're chatting with friends, staying alert to traffic, or just soaking up the vibes. Your sounds, your choice. Rock both ACCENTUM Open earbuds or just one if you want to stay aware of what's happening around you. Perfect for social butterflies!

 

All-day play for all-day slay. All-day listening, rain or shine.

With up to 28 hours of total playtime, you'll likely run out of energy before your earbuds do. From the morning commute to after-hours fun, ACCENTUM Open keeps the music rolling without missing a beat. And with IPX4-rated splash and sweat resistance, your wireless earbuds keep performing, rain or shine, no matter what you're up to.

 

Feel your tunes, not the earbuds. Meet your perfect fit.

With the comfort of barely-there earbuds, ACCENTUM Open earbuds are the perfect choice if you find ear canal designs too insulating or too large to fit securely. Plus, the open-ear stem design means no uncomfortable pressure or ear canal invasions. Your lightweight, breathable earbuds stay in place and feel weightless all day long, with a handy stem that makes them easy to pop in and out whenever you like.

 

Effortless use, no manual needed. Keep it simple, keep it smart.

Life's complicated enough already - ACCENTUM Open earbuds keep things simple. Multipoint connectivity lets you seamlessly switch between two devices, so you're always in sync, whether it's videos, calls, or music. No need to fumble with settings. Smart touch controls make everything intuitive - no manual required. Smart Pause stops playback the moment you remove an earbud, and the dual beamforming microphones, combined with AI-based noise reduction, ensure crystal-clear calls. Just connect and go. Now that's music to your ears.

I was skeptical as these earbuds are quite cheap for a Sennheiser product but they have been worth their weight in gold.
Snug fit in the ear, they feel very secure and I've not had one drop out on its own.
Sound is clear and with the open ear, I can still hear my immediate surroundings as I walk around in public. I brought them specifically for commuting to and from work.
I made the dire mistake of leaving them in a jacket pocket as the jacket went through the wash (and dryer). I left them in the boiler cupboard from 3 days and amazingly they still worked! It's been several months since, and they haven't suffered a delayed death. Best inv...view more
