Motorola RMN5114 Lightweight Temple Transducer

What is the RMN5114?

The Motorola RMN5114 is a lightweight bone-conduction temple transducer headset designed for use with Motorola business two-way radios across the CLS, DLR, DTR, RDM, RDX, RM, and XTN series. It transmits audio as vibrations through the temples and bones of the skull directly to the inner ear, leaving the ear canal open so the user can simultaneously hear both radio communication and ambient sounds. The headset includes an in-line push-to-talk (PTT) button and microphone, allowing hands-free operation without removing the radio from a holster or belt clip.

Who This Product Is For

The RMN5114 is used in environments where workers need continuous radio communication but cannot use a conventional earpiece or over-ear headset — either because of safety requirements, hearing-protection regulations, or the physical constraints of the work environment.

Construction and industrial sites: Workers wearing hard hats cannot use over-the-head headsets. The RMN5114's behind-the-head design and temple-mounted receivers fit comfortably under or alongside a hard hat without interference, and the open-ear design ensures workers can hear site audio and warning signals.

Warehousing and distribution: Forklift operators, loading dock workers, and warehouse staff often need hands-free communication while operating equipment. The RMN5114 keeps the ears free to hear backup alarms, PA announcements, and colleagues without removing the headset.

Manufacturing and factory operations: In loud factory environments, workers may be required to wear hearing protection. Because the RMN5114 transmits audio via bone conduction, it can be used simultaneously with foam or standard earplugs — allowing workers to stay on-channel while protecting their hearing.

Security and event staff: Security personnel and event coordinators need discreet, reliable communication. The RMN5114's low-profile design is less visually prominent than a standard earpiece or over-the-head headset.

Film and broadcast production: Production crews working on set value the open-ear design because crew members need to monitor set audio and verbal cues from directors while staying on the radio channel. The RMN5114 has been used by production audio departments for this reason.

Assistive use: Some users with certain types of hearing loss or hearing differences find bone-conduction audio more effective than conventional speaker-based audio. Because the RMN5114 bypasses the outer and middle ear and transmits vibrations directly to the inner ear, it may be usable by individuals for whom traditional earpieces are ineffective. This should be evaluated on an individual basis.

Key Features

• Bone-conduction audio delivery: two temple receivers rest against the sides of the head and convert electrical audio signals into vibrations that travel through the skull bones to the cochlea, without requiring the ear canal to be occluded
• Open-ear design allows simultaneous monitoring of radio audio and surrounding environmental sounds
• Compatible with hearing protection earplugs worn at the same time — the vibration-based transmission is not affected by foam earplugs in the ear canal
• Behind-the-head headband fits under or alongside hard hats and helmets that would block conventional over-the-head headsets
• In-line PTT button allows radio transmission without removing the radio from a holster or belt clip
• In-line microphone positioned for voice pick-up during PTT operation
• Clothing clip included for securing the PTT/microphone cable during use
• Broad compatibility across multiple Motorola business radio series using the standard Motorola 2-pin connector
• One-year Motorola OEM replacement warranty

Compatible Models

The RMN5114 is compatible with Motorola business two-way radios that use the standard Motorola 2-pin connector, including the following confirmed models:

If your radio is not listed above, verify the connector type before ordering. The RMN5114 requires the standard Motorola 2-pin connector. It is not compatible with Motorola MOTOTRBO, APX, or Ion series radios, which use different connector formats.

Frequently Asked Questions

How does a temple transducer headset work differently from a standard earpiece?

A standard earpiece places a speaker directly in or over the ear canal and delivers audio through the air as sound waves. A temple transducer works differently: the two receiver pads rest against the temples — the flat area of the skull on either side of the head — and convert audio signals into mechanical vibrations. Those vibrations travel through the bones of the skull to the cochlea in the inner ear, where they are interpreted as sound. Because the ear canal is never blocked, the user simultaneously hears radio audio through bone conduction and ambient environmental sounds through normal hearing. This is the same fundamental mechanism used in bone-conduction hearing aids and some consumer sport headphones.

Can I use the RMN5114 while wearing hearing protection earplugs?

Yes. Because the RMN5114 transmits audio via bone conduction rather than through the air in the ear canal, foam or standard industrial earplugs in the ear canal do not block the audio signal. Workers who are required to wear hearing protection in high-noise environments — such as manufacturing floors, airport tarmacs, or heavy construction sites — can wear earplugs and still receive radio audio through the temple transducer. This is one of the primary operational advantages of this headset type compared to conventional earpieces.

Will the RMN5114 fit under a hard hat or safety helmet?

The RMN5114 is designed specifically with this use case in mind. It uses a behind-the-head headband rather than an over-the-head band, which means it does not conflict with the interior suspension of a standard hard hat. The temple receiver pads position at the sides of the head and do not extend above the crown. Most users are able to wear the RMN5114 with a standard Type I or Type II hard hat without modification. Fit may vary depending on hard hat model and individual head size, and Motorola does not certify specific hard hat compatibility.

What is the difference between RMN5114, RMN5114A, RMN5114B, and RMN5114C?

These are revision suffixes applied by Motorola to the same base product as minor manufacturing or component updates are introduced over time. They are functionally equivalent and are compatible with the same radio models. The base part number RMN5114 refers to the original release; subsequent letter suffixes (A, B, C) denote incremental revisions. Motorola and authorized dealers typically ship the current revision when the base part number is ordered. If a specific revision is required for regulatory or procurement documentation, confirm with the seller at the time of ordering.

Is the RMN5114 compatible with Motorola MOTOTRBO or APX radios?

No. The RMN5114 uses the standard Motorola 2-pin connector found on the CLS, RM, RDX, DTR, DLR, AX, and XTN series business radios. Motorola MOTOTRBO radios (such as the DP or XPR series) and APX series public safety radios use different connector configurations and are not compatible with the RMN5114. Motorola offers separate audio accessories for MOTOTRBO and APX platforms. If you are unsure which connector your radio uses, contact us before ordering.

Can the RMN5114 be used by someone with hearing loss?

Because the RMN5114 delivers audio via bone conduction, it may be functional for individuals with certain types of conductive hearing loss — conditions where sound cannot travel normally through the outer or middle ear but the cochlea (inner ear) remains functional. For individuals with sensorineural hearing loss (damage to the cochlea or auditory nerve), the benefit would be limited for the same reasons that bone-conduction hearing aids have limited effectiveness in those cases. The RMN5114 is not a medical device and Motorola does not market it as a hearing aid. Any individual considering the RMN5114 for hearing-related accessibility should evaluate it under the guidance of an audiologist or hearing specialist.

Does the RMN5114 include a PTT button, or do I need to press PTT on the radio?

The RMN5114 includes an in-line PTT (push-to-talk) button integrated into the cable assembly, along with an in-line microphone. Pressing the in-line PTT button transmits audio captured by the in-line microphone. The user does not need to remove the radio from a holster or handle the radio body to transmit. A clothing clip is also included to secure the PTT cable to a shirt collar or outer garment for easy reach.
