What's in the Box
The PMLN8311 ships as a single assembled unit. Each package contains:
- One single-wire C-ring earpiece with attached coil cord and 2.5mm single-pin angled connector
- One in-line PTT/microphone module with lapel clip (attached to the cord)
- One removable medium ear tip (installed on the earpiece)
Who This Product Is For
The PMLN8311 is built for organizations already running Motorola Curve (DLR110) radios that need discreet, hands-free audio for staff who can't keep a radio at their mouth during a shift. The single-wire design keeps the cable footprint minimal, and the lapel-clipped PTT means the radio can stay holstered while a user listens and transmits.
Common environments where this accessory is deployed include:
- Hospitality: Front desk, housekeeping, valet, and banquet staff who need to coordinate quietly in guest-facing areas.
- Retail: Floor associates and stockroom teams who move between aisles and storage and need to keep a hand free for merchandise.
- Warehousing and logistics: Pickers and dock workers who require audio that stays in place while handling product.
- Education: Campus, facilities, and event staff who want low-profile communication in classroom and common-area settings.
- Healthcare and senior living: Staff who benefit from an earpiece that can be wiped down with an alcohol pad and shared across shifts.
The over-the-ear C-ring fit and reversible ear placement make it a practical choice when a single accessory is shared among multiple users rather than assigned to one person.

Frequently Asked Questions
Which radios is the Motorola PMLN8311 compatible with?
The PMLN8311 is designed for the Motorola Curve (DLR110) business two-way radio.
What type of connector does the PMLN8311 use?
It uses a 2.5mm single-pin angled connector with a twist-and-lock mechanism. The twist-and-lock design holds the plug in the radio's audio jack to reduce accidental disconnection and wear on the connector during a shift.
Can the PMLN8311 be worn on either ear?
Yes. The C-ring over-the-ear design is reversible and can be positioned on the left or right ear. This makes it practical for sharing a single earpiece across staff or shifts.
Does the PMLN8311 have a push-to-talk button, or do I use the radio's PTT?
It includes an in-line PTT button on the cable, paired with a lapel clip. You can clip the PTT to your collar or lapel and transmit without removing the radio from its holster. The radio's own PTT remains functional as well.
Can the PMLN8311 be cleaned and shared between employees?
Yes. Motorola states the earpiece can be wiped down with an alcohol pad between users, which makes it suitable for environments where one accessory is rotated among multiple staff members. The ear tip is removable for cleaning or replacement.
Is the PMLN8311 a genuine Motorola part?
Yes. The PMLN8311 (also cataloged as PMLN8311A) is an OEM Motorola Solutions accessory. Tech Wholesale is an authorized Motorola dealer, so units are sourced through the manufacturer's supply chain and carry standard Motorola accessory warranty coverage.
