Sennheiser Accentum Open TWS headphones review: High on comfort, fit, and battery life

Sennheiser is more well-known for its headphones than for its TWS models, and the company has been launching TWS models for a few years now, with the Accentum Open being the latest pair, currently priced at ₹9,999. These are open-stem, wireless earbuds that aim to offer lightweight buds for those seeking Bluetooth earbuds on the go. 

 

Sennheiser Accentum Open features open-designed stem-styled wireless buds that are pretty lightweight. The outside of the stem features a touch panel that can be used to put the device in pairing mode, adjust the volume (long-tap the left bud to decrease and the right one to increase), and enable or disable Smart Pause. 

 

The touch controls are pretty responsive, with the buds catching your touch more often than not after you’re used to the touch panel. The buds are IPX4 splash resistant so should be okay for gym use but certainly not made for any water-related activities. 

 

The case is also lightweight and doesn’t catch fingerprints quickly, though you would still need to give it a wipe if you want to avoid any smudges. The bottom side of the case houses the LED indicator as well as the USB Type-C port. What I didn’t like about the case is that hinge—it tends to close too frequently on the slightest touch and doesn’t necessarily seem assuring when opening and closing intentionally. 

 

I found these comfortable to wear, and the open design definitely plays a part. While there’s no active noise cancellation, many people would overlook this considering how well these fit and feel, even when worn for longer periods. 

 

The buds have 11mm drivers and support Bluetooth 5.3 (with Bluetooth LE) along with SBC and AAC audio codecs, and not any other one. Regarding its audio quality, the Accentum Open generally produces a balanced output with decent bass for a pair of open TWS. The treble is handled well, resulting in an overall clear sound that allows background instruments to shine without compromising vocals. These can get loud without any distortion for several genres. Mic quality is decent, but not the best for TWS when making calls outdoors.  

 

The buds pause when one is removed from the ear, and you can also use only one at a time if you want. You can also connect these two devices simultaneously for juggling between work and play.  

 

The buds didn’t work with the Sennheiser Smart Control Plus app, but I didn’t feel as if I was missing out on anything due to that. Both buds feature a 36mAh battery, and the case boasts a 400mAh battery, offering 6.5 to 7 hours of playback with an additional 20 hours when the case is used. This is not bad for daily use, and the buds also support fast charging, offering approximately 1.5 hours of use with just 10 minutes of charging. 

 

In summary, if you prefer comfort and balanced sound from your earphones, the Sennheiser Accentum Open are an option worth consideration at the current price point. Not many open-back TWSs are available, so that is your preference. These might just be your TWS to have, whether using with an Android smartphone, an iPhone or a Windows laptop.
