Niecase DG09 Open-Ear Bluetooth Headphones with Dual Noise-Cancelling Mic

On-body feel

For people who need to take calls while keeping their ears open to nearby sounds, the Niecase DG09 combines an open-ear fit with a boom microphone. It’s designed for work calls, office meetings and travel, as well as listening during fitness activities.

At 29.5 g, the headset has a lightweight frame wrapped in silicone. Its flexible construction is designed to adapt to the wearer, while the open-ear design leaves the ear canal unblocked. That makes it a practical alternative to in-ear earbuds when awareness of your surroundings matters.

Use the 240° rotatable boom to position the microphone for calls, then control calls and audio with the built-in button. The fit and controls keep everyday tasks straightforward, whether you’re moving between meetings or taking a call from your laptop.

Pros

Two noise-cancelling microphones and DSP noise reduction are designed to focus on your voice and reduce background distractions during calls. The boom’s adjustable angle lets you position the pickup close to your mouth, a useful feature for remote work, teaching online or office conversations. This emphasis on voice calls sets the DG09 apart from simple open-ear headphones focused mainly on music.

Bluetooth 5.4 supports wireless connection, and multipoint pairing lets the headset connect to two devices at once. For example, you can pair a cell phone and laptop and move between calls and audio without repeatedly disconnecting and pairing. The multi-function button handles playback and call actions without needing to reach for your device.

The stated battery life is up to 10 hours of music or talk time, with a full charge taking about two hours through USB Type-C. Buyers also speak positively about the case, durability and appearance, while fit opinions are mixed. Those impressions offer useful context alongside the adjustable, open-ear design.
