Ear hook headset No name HP Poly CS540 Earloops and Earbuds model 85Q18AA, earhook and in-ear combo

HP Poly CS540 Earloops and Earbuds ear hook and in-ear combo is an accessory set designed to provide two wearing options for single-ear communication: a soft earhook (earloop) and compact in-ear earbuds. The set is intended for users of compatible wireless headsets who need a secure, interchangeable fit for voice calls in office, contact center or mobile environments. It allows quick switching between an over-ear loop that secures the headset behind the ear and an in-ear bud for a closer, more isolated fit, while maintaining microphone alignment and call clarity.

Advantages

The accessory set offers flexibility with two distinct wearing styles in one package, enabling users to choose a preferred comfort and fit without replacing the headset. Materials and form factor are optimized for stable single-ear use, reducing the need for frequent adjustments during long shifts. Design focuses on maintaining audio and microphone positioning when changing attachments, supporting consistent call performance across various environments.

Suitable for

• Contact center and call centre agents who require a stable single-ear headset option
• Office telephony and unified communications where quick adjustment between earhook and in-ear is useful
• Mobile professionals who need a secure fit during movement
• Users who prefer the option to switch between less-isolating earhook wear and more-isolating in-ear earbuds

Key specifications

• Compatibility: designed as accessories for compatible single‑ear wireless headsets
• Included items: one earhook (earloop) and one in‑ear bud set for single‑ear use
• Fit type: over‑ear loop for stable behind‑ear mounting and in‑ear for closer fit
• Usage: voice communication, single‑ear listening and talk applications
• Materials: lightweight plastics and silicone ear tip for comfort and grip

How to use

Attach the chosen accessory to the headset’s ear connector following the headset manufacturer’s attachment method: align the earhook or in‑ear bud with the headset coupling point and press until it clicks into place. For earhook use, place the loop over and behind the ear to hold the headset securely; position the microphone boom toward the mouth for optimal voice pickup. For in‑ear use, insert the silicone tip gently into the ear canal to achieve a comfortable seal and check microphone alignment. Swap between attachments by gently releasing the fitted piece and replacing it with the other option, ensuring each is fully seated before wearing.

Usage recommendations

Regularly inspect the ear tip and earhook for wear or damage and replace if fit or comfort degrades. Clean silicone tips with a damp cloth and mild soap, avoiding harsh chemicals. When using in noisy environments, choose the in‑ear option for better isolation; select the earhook when awareness of surroundings is required. Follow the headset manufacturer’s guidance for attachment and removal to avoid damaging connectors.
