Sennheiser has introduced its Accentum Open TWS earphones in India, priced at ₹9,990. These earbuds sport an open-ear design and come equipped with AI-powered noise reduction, an IPX4 splash resistance rating, and a battery life of up to 28 hours. They feature Bluetooth 5.3 connectivity with multipoint pairing, Smart Pause functionality, and support for wireless charging.
Design & Build Quality
The Accentum Open earbuds sport a sleek, minimalist look, available in Forest Cream and Black. The charging case is compact, lightweight, and slips easily into any pocket. While it feels premium in hand, it can pick up scratches and smudges over time. The open-ear fit rests comfortably on the outer ear, allowing ambient sounds in — a plus for runners and cyclists who need situational awareness.
With an IPX4 splash resistance rating and a five-star drop resistance certification, these earbuds are built to withstand light workouts, outdoor runs, and minor drops.
Display of Sound: Audio Performance
If Sennheiser is known for anything, it’s audio excellence — and the Accentum Open doesn’t disappoint. Powered by 11mm dynamic transducers, the sound profile is balanced yet lively, delivering rich bass without overpowering mids and highs. Whether it’s orchestral music or bass-heavy EDM, the earbuds maintain clarity and punch.
For calls, dual beamforming microphones and AI noise reduction ensure your voice remains crisp, even in moderately noisy environments. However, these earbuds do not feature Active Noise Cancellation (ANC) — a conscious choice by Sennheiser to prioritize awareness of surroundings.
