Dell Pro Plus EB525 specifications and in-depth review

Dell Pro Plus EB525

Manufacturer: Dell

The Dell Pro Plus EB525 are true wireless in-ear earbuds designed for professionals who need reliable audio and hands-free communication throughout the workday. Built around active noise cancellation, they also include an ambient sound mode, letting users switch between focused listening and staying aware of their surroundings. A noise-canceling microphone, mute function, and headset capability round out a feature set clearly aimed at calls and conferencing scenarios. The earbuds ship with a travel bag and support multipoint connectivity across two devices simultaneously.

On the technical side, the EB525 runs on Bluetooth 5.3 with a stated maximum range of 30 m and charges via USB Type-C. Battery life with ANC active reaches 8 hours, backed by a 500 mAh charging case, and wireless charging is supported alongside fast charging. The frequency response spans 20 Hz to 20,000 Hz with a sound pressure level of 106 dB/mW. An IP54 ingress protection rating provides resistance to sweat and light moisture, and stereo playback is delivered through both earbuds without any RGB lighting or display components onboard.

Pros
  • Supports multipoint connection to two devices at once, useful for switching between a phone and laptop without re-pairing
  • Both active noise cancellation and passive noise reduction are present, providing dual-layer sound isolation
  • Wireless charging is supported alongside fast charging, adding flexibility to how the case is topped up
  • The charging case holds 500 mAh, offering meaningful additional charge beyond the earbuds' own 66 mAh battery
  • A mute function and noise-canceling microphone make the earbuds practical for voice calls and online meetings
  • A travel bag is included in the box, providing a ready solution for carrying and storing the earbuds
Cons
  • No in-ear detection means music will not automatically pause when the earbuds are removed
  • Fast pairing is not supported, so initial and repeated device pairing requires manual steps
  • No advanced audio codecs such as LDAC, aptX, or AAC are available, limiting audio transmission options
  • Spatial audio, Dolby Atmos, and Dirac Virtuo are absent, which may matter to users who prioritize immersive sound
  • No find device feature is available, making it harder to locate misplaced earbuds
Who is this for?

These earbuds are a strong fit for professionals who spend a significant portion of their day on calls and virtual meetings, thanks to the combination of a noise-canceling microphone, mute function, and headset capability. The dual-layer noise reduction — both active and passive — makes them well suited to open office environments or shared workspaces where ambient noise is a persistent distraction. Users who regularly move between devices will also benefit from multipoint connectivity across two devices, while wireless and fast charging support means the case can be topped up quickly without hunting for a specific cable. The included travel bag and sweat-resistant IP54 rating add practical value for those who commute or carry their gear daily.

Who is this NOT for?

Users who prioritize high-fidelity wireless audio will find the lack of advanced codecs limiting, as LDAC, aptX in any form, and AAC are all absent, leaving the earbuds without the transmission quality that audiophiles typically look for. The absence of spatial audio, Dolby Atmos, and Dirac Virtuo makes these a poor match for anyone seeking an immersive listening experience for music, gaming, or cinematic content. Additionally, users who want smart convenience features such as automatic playback pausing when removing the earbuds, a find device function, or notification reading will find none of those capabilities here, which may frustrate those accustomed to a more feature-rich daily driver.
