Introducing the Sennheiser ACCENTUM Clip: A Revolutionary Open-Ear Bluetooth Headset with LDAC Technology

Sennheiser has recently unveiled the ACCENTUM Clip, a unique open-ear true wireless earbud that falls into the clip-style category rather than the traditional in-canal design seen in most true wireless models. This announcement came from Hanover, Germany, where Sennheiser paired a 12 mm dynamic driver with Bluetooth 6.0, LDAC support, and an IP54 rating. The earbuds boast up to 36 hours of total playtime with the charging case and are positioned within Sennheiser’s ACCENTUM line, which is positioned below the flagship MOMENTUM range.

Friederike Menking, the product manager for the ACCENTUM Clip, expressed that the goal was to elevate the level of acoustic performance that open earbuds have struggled to achieve. With open-ear designs leaving the ear canal unobstructed, wearers can simultaneously hear surrounding sounds and their music. Sennheiser claims that the ACCENTUM Clip achieves ambient awareness through its physical design rather than electronic pass-through, eliminating the need for a microphone-fed transparency mode often found in closed earbuds with active noise cancellation.

Design and Fit:

The ACCENTUM Clip adopts an intra-concha wearing style, where the driver housing rests in the outer ear’s bowl instead of being inserted into the ear canal. A flexible silicone bridge connects the two halves of each earbud, ensuring a secure fit across various ear shapes. Each earbud weighs 6.8 g, with both earbuds and the charging case together weighing 57 g. The case alone weighs 43 g.

Each earbud features textured touch controls for volume, calls, and playback. The IP54 rating provides protection against dust ingress and water splashes from any direction, although it applies to the earbuds only and not the charging case. To minimize sound leakage, the speaker geometry and internal damping are meticulously designed to contain audio within the wearer, addressing a common concern with open-ear products.

Sound and Audio Specification:

Central to each earbud is a 12 mm dynamic driver, with the ACCENTUM Clip carrying Hi-Res Audio Wireless certification. The speaker frequency range spans from 20 Hz to 40 kHz, with a speaker sensitivity of 128 dB SPL at 1 kHz and 1 mW. Total harmonic distortion is below 0.5% at 1 kHz and 100 dB SPL, and a Dynamic EQ feature adjusts tuning as volume changes to maintain balance and limit distortion.

Connectivity and Codecs:

Operating on Bluetooth 6.0, the ACCENTUM Clip supports standard SBC and AAC codecs, with LDAC available on compatible devices for higher bitrate streaming. Bluetooth profiles include A2DP, AVRCP, and HFP, operating within the 2,402 MHz to 2,483.5 MHz band. Multipoint connectivity allows two source devices to remain connected simultaneously, and each earbud can function independently. Google Fast Pair facilitates quick pairing on Android devices, with Auracast branding present alongside Bluetooth, LDAC, and Hi-Res Audio Wireless marks on the packaging.

Microphones and Calls:

Each earbud houses a dual-microphone system, featuring two microphones per side with MEMS elements. The microphones cover a frequency range of 100 Hz to 10 kHz and are paired with an AI noise reduction algorithm to isolate the wearer’s voice from background noise during calls.

Battery and Charging:

The ACCENTUM Clip offers up to 9 hours of playtime on a single earbud charge, with the charging case providing three additional top-ups for a total of up to 36 hours. A 10-minute charge yields 2 hours of playback, and both earbuds and the case fully charge in approximately one hour at room temperature. The case has a 545 mAh battery, while each earbud ranges between 49 and 55 mAh due to dual sourcing of battery components. Charging occurs over USB-C at 5 V, with built-in lithium-ion batteries in both the earbuds and case.

App and Software:

The ACCENTUM Clip is compatible with the Sennheiser Smart Control Plus app, offering a 5-band equalizer, shareable EQ presets, and a guided Sound Check feature for sound setup. The app manages connectivity settings and additional personalization features, with potential software expansions through firmware updates.

Colours, Packaging, and Spare Parts:

Although the launch material mentions Black and Cream colorways, the technical data sheet lists a third option, Ice Blue. Spare parts cover all three colors, indicating Ice Blue’s inclusion in the range. The ACCENTUM Clip ships in zero-plastic packaging, comprising 43 g of paper and cardboard. Designed in Germany and manufactured in China, the earbuds and charging case are available as separate spare parts in each color, promoting longevity and sustainability.

Availability and Price:

The ACCENTUM Clip will be available in the UK starting from July 23, 2026, through uk.sennheiser-hearing.com and selected retailers, priced at £149. Equivalent prices in other regions are 179 euros and $289.95 in Australian dollars. The package includes the earbuds, charging case, USB-C charging cable, and documentation.
