Description:

The Dell Pro Plus Earbuds EB525 combine AI powered voice isolation, adaptive active noise cancellation, and certified Microsoft Teams performance to support clear, distraction free communication. With Bluetooth 5.3 multi point connectivity, fast charging, wireless charging support, and a comfortable in ear design with multiple ear tip sizes, these earbuds are ideal for professionals who need dependable audio, smart controls, and all day comfort across multiple devices.

Features:

Clear communication in any workspace
Experience consistent voice clarity thanks to an AI based noise cancelling microphone that is engineered to recognise your voice and reduce background distractions. This intelligent voice filtering ensures calls sound natural and professional even in busy environments such as open offices or shared workspaces.

AI powered voice precision
The integrated MEMS microphone technology works with advanced voice processing to separate speech from surrounding noise. Compared to standard earbud microphones, this approach delivers noticeably improved call quality for meetings, virtual collaboration, and everyday conversations.

Certified for professional calls
These earbuds are certified for Microsoft Teams open office environments and also support Zoom, making them a reliable choice for business communication. Voice isolation technology helps ensure your message is heard clearly while minimising nearby noise for your audience.

Adaptive noise control for focus or awareness
Switch easily between adaptive active noise cancellation and enhanced transparency mode using intuitive touch controls. Adaptive ANC automatically adjusts to your surroundings, while transparency mode allows natural ambient sound when you need to stay aware of what is happening around you.

Simple touch controls
On device controls let you answer or reject calls, manage music playback, adjust volume, and toggle noise modes with simple gestures, keeping your workflow smooth and uninterrupted.

Comfort designed for long days
Four ear tip sizes help create a secure and comfortable fit for extended use. The in ear design supports effective noise isolation while remaining comfortable enough for all day wear. Water and dust resistance add durability for everyday use.

Reliable wireless connectivity
Bluetooth 5.3 delivers faster, more stable connections and supports pairing with up to eight devices, with two connected at the same time. This makes it easy to switch between your laptop, phone, and other devices without interruption.

Seamless Dell ecosystem integration
Dell Pair allows instant connection with compatible Dell laptops and desktops, creating a streamlined experience across your Dell devices. The Dell Display and Peripheral Manager provides centralised control and optimisation for supported peripherals.

Personalised audio control
Using the Dell Audio mobile app, users can customise sound profiles, adjust equaliser settings, manage controls for calls and media, update firmware, and locate misplaced earbuds using the Find My Earbuds function.

Built for productivity and manageability
IT teams can manage these earbuds at scale through the Dell Device Management Console, improving efficiency with cloud based oversight and expanded command line interface support.

Battery performance that keeps up
Enjoy up to 5 hours of talk time or 8 hours of listening time with active noise cancellation enabled on the earbuds alone, with extended use available through the charging case. Fast charging delivers quick power boosts to keep you moving through your day.

Compatibility and platform support
The earbuds are compatible with Windows 10, Windows 11, iOS, Android, and macOS, making them a flexible audio solution for mixed device environments.
