Sennheiser has introduced the HDB 360, a new wireless headphone model engineered to deliver high-resolution audio whether you connect via cable or Bluetooth. Even smartphones that lack the latest Bluetooth codecs can now experience superior sound quality, thanks to an included USB-C transmitter dongle. While the HDB 360 shares its chassis design with the Momentum 4 released in 2022, it features a completely new acoustic system tailored for focused listening, along with active noise cancellation and outstanding battery performance.
When used with a USB-C or 3.5mm audio cable, the HDB 360 supports high-resolution audio up to 24-bit/96 kHz. For wireless listening, the headphones utilize the aptX Adaptive Bluetooth codec. Since only a small number of smartphones currently support aptX Adaptive, Sennheiser bundles a wireless dongle to ensure compatibility across a wider range of devices. This thoughtful inclusion means users won’t need to upgrade their phone just to enjoy high-quality wireless audio.
Each ear cup houses a 42-millimeter driver, tuned by Sennheiser for accurate and faithful sound reproduction. Battery life remains impressive, matching the Momentum 4 with up to 60 hours of playback on a single charge when active noise cancellation is enabled. A quick 10-minute charge provides around seven hours of listening time, making these headphones ideal for travel or long listening sessions.
The Sennheiser Smart Control Plus app unlocks deeper customization, offering a parametric equalizer that allows precise sound adjustments. Users can modify bandwidth, apply filters, and even A/B test different EQ settings in real time. A future app update is expected to introduce a feature that lets you share your custom EQ presets with others via QR code, adding a social element to personal audio tuning.
Available for preorder at $499.95, the HDB 360 package includes a carrying case, USB-C and audio cables, the wireless transmitter dongle, and an airplane adapter. Shipping is scheduled to begin on October 21, 2025. While priced higher than the original launch cost of the Momentum 4, the HDB 360’s added features, including the dedicated dongle and enhanced app control, position it as a compelling upgrade for audiophiles seeking both convenience and uncompromising sound quality.
