When choosing an earpiece for your two-way radio, the right option depends largely on your working environment, how much discretion you need, and whether the equipment will be used by one person or shared between multiple team members.

At Light of Night, two of our most popular styles are D-Shape earpieces and covert acoustic tube earpieces. Both provide reliable radio communication, but they are designed for quite different applications.

D-Shape Earpieces: Robust, Practical and Easy to Use

A D-Shape earpiece is an over-the-ear headset featuring a rubber loop shaped like the letter “D”. The loop sits securely around the outside of the ear rather than inside the ear canal.

Our D-Shape earpiece range includes options for Motorola, Hytera, Kenwood, Vertex/Yaesu, Entel, Icom and other popular two-way radio brands.

Best suited to:

• Warehouse and logistics teams
• Event stewards and event staff
• Retail teams
• Security teams where discretion is not the main priority
• Environments where radios and earpieces are shared between shifts

Why choose a D-Shape earpiece?

D-Shape earpieces are designed with durability, grip and ease of use in mind. Because the earpiece sits around the outer ear rather than inside the ear canal, it can also be easier to clean between users.

For example, our adjustable D-Shape earpiece for Motorola two-pin radios features a rubber ear loop, an inline microphone, a large push-to-talk (PTT) button and a rotating metal clip designed to provide a secure fit while on the move.

Useful tip: If several members of your team share equipment, choose an earpiece that is easy to wipe down and establish a simple cleaning routine between shifts.

Covert Earpieces: Discreet and Professional

Covert earpieces are designed for situations where a low-profile, discreet appearance is important. Most models use a transparent acoustic tube that runs from the speaker to the ear, making the earpiece considerably less noticeable than a conventional over-the-ear design.

Explore our range of covert earpieces for two-way radios.

Best suited to:

• Security professionals
• Close protection teams
• Hospitality and front-of-house staff
• Discreet event security
• Situations where maintaining a professional appearance is important

Why choose a covert earpiece?

The transparent acoustic tube and separate microphone/PTT arrangement allow the radio equipment to remain much less visible. This makes covert earpieces particularly useful when communication is essential but you do not want the equipment to distract from your professional appearance.

For example, our 3-wire covert earpiece for Motorola R2 uses a transparent, changeable acoustic tube with separate microphone and PTT components, allowing the controls to be positioned discreetly on clothing or elsewhere on the body.

We also stock a covert earpiece for compatible Hytera radios, featuring a changeable transparent acoustic tube and a lapel microphone.

Useful tip: If discretion is your priority, consider where the microphone and PTT will sit before choosing your earpiece. A well-positioned microphone can make the whole setup significantly less noticeable.

Which Earpiece Should You Choose?

Our Popular Options

We supply a wide range of radio accessories for different manufacturers and radio models. Among our most popular choices are:

• Adjustable D-Shape Earpiece for Motorola 2-Pin Radios – a practical choice for compatible Motorola radios, including models such as the DP1400 and CP040.
• Adjustable D-Shape Earpiece for Hytera Radios – designed for compatible Hytera radios with a 2-pin and single-screw socket.
• 3-wire covert earpiece for Motorola R2 – a discreet option with a transparent acoustic tube, separate microphone and PTT.
• Covert Earpiece for Hytera – suitable for compatible Hytera PD7, PD9 and PT5 series radios.

Important: Always check the connector type and your exact radio model before ordering. Two radios from the same manufacturer can use different connectors, so compatibility should be confirmed before purchasing.

Pro Tip: How to Clean a Covert Acoustic Tube

Regular maintenance is important for keeping a covert earpiece working properly. Earwax, moisture and dust can accumulate in the acoustic tube over time, potentially reducing audio quality.

Easy Cleaning Steps

1. Inspect the tube. Check for visible debris, moisture or other blockages.
2. Remove the tube. Carefully disconnect the acoustic tube from the speaker/transducer assembly if your model has a removable tube.
3. Clean the tube. Soak the disconnected tube and ear insert in warm, not hot, water for approximately 10–15 minutes. Avoid detergents or harsh cleaning chemicals unless the manufacturer specifically recommends them.
4. Clear any remaining debris. After cleaning, allow the tube to drain thoroughly. If using compressed air, use it carefully and according to the manufacturer’s recommendations.
5. Dry completely. Allow all components to air dry fully before reconnecting the tube to the speaker/transducer or radio.

Safety tip: Never connect a wet or damp acoustic tube to your radio equipment. Moisture can damage electronic components. If you are cleaning equipment used by multiple people, follow your organisation’s hygiene procedures and the manufacturer’s cleaning instructions.

Keep Your Radio Communications Clear and Comfortable

The best earpiece is ultimately the one that matches the demands of your job. Choose a D-Shape earpiece when durability, stability and ease of cleaning are your priorities. Choose a covert acoustic tube earpiece when discretion and a low-profile appearance matter most.

In venue security and event management, two-way radios are the lifeline of your operation. When an incident occurs or a crowd control issue arises, communication needs to be instant. But even the most rugged, high-end radio is only as reliable as the battery powering it.

Improper charging and storage are the single biggest causes of premature battery failure. This doesn’t just mean unnecessary equipment costs; it means the safety risk of a dead radio right in the middle of a shift.

By implementing these professional maintenance habits, you can significantly extend your radio batteries’ lifecycle, boost performance, and protect your investment.

1. Daily Charging Best Practices

How your team handles their daily charging routine dictates how many months (or years) you get out of your battery packs. Keep these core rules in mind:

• Turn the Radio Off: Always power down your radio before sliding it into the cradle. Leaving it on causes the radio to continuously draw current while charging. This confuses the charger’s internal circuitry, which can result in incomplete charging cycles and shortened lifespans.
• Ditch the “Storage Stand” Habit: Avoid using your charging dock as a permanent desk stand when the radio is already full. Continuous trickle charging (or “top-up” charging) on standard chargers slowly degrades the battery’s chemical health, permanently lowering its capacity.
• Avoid Deep Discharges: Modern Lithium-ion (Li-ion) batteries don’t suffer from the old “memory effect” of past tech. You do not need to drain them to 0% to keep them healthy. In fact, deep discharges stress the battery; it’s best to pop them on the charger when they drop to around 20–30%.
• Initialise New Batteries Properly: When unboxing a brand-new battery, it needs to be “initialised.” Leave it in the charger for an extra 1–2 hours after the indicator light turns green. This ensures all cells are perfectly balanced and reach their maximum potential capacity.
• Stick to the Right OEM Charger: Mismatched or cheap, third-party “bargain” chargers are a major risk. They lack proper voltage regulation, which can lead to overheating, cell damage, and even potential fire hazards. Always use official chargers designed for your exact radio model.

2. Off-Season & Fleet Storage Rules

If you manage a large fleet, a major portion of your inventory likely sits idle during seasonal downtime. How you store those batteries determines whether they will actually turn on when you next need them.

• The 50% Rule: Never store a battery completely full or completely empty for long periods. If you are taking a battery out of service for more than 30 days, ensure it sits at roughly 50% capacity to keep its internal chemistry stable.
• Control the Temperature: Extreme temperatures are the ultimate enemy of battery lifespan. Store your equipment in a cool, dry environment—ideally between 15°C and 25°C. Avoid damp basements, freezing storage units, or hot vehicles, which can cause permanent capacity loss.
• Keep the Contacts Clean: Over time, the metal battery terminals accumulate oxidation, dust, and natural skin oils from handling. This buildup acts as an insulator, resisting power transfer. Periodically wipe down the contacts on both the battery and the radio with a clean, dry microfiber cloth.
• Rotate Your Inventory: Don’t let the same half of your fleet do 100% of the heavy lifting while the other half sits in a box for two years. Use a simple spreadsheet or a label maker to log and rotate your battery inventory, ensuring equal wear across the board.

3. Four Red Flags: When to Replace

Even with flawless maintenance, chemical batteries are consumable items that will eventually degrade. Keep a close eye out for these clear warning signs that a battery is a liability and needs to be retired:

1. Rapid Drain: The battery goes from a full charge to flashing red within just a fraction of its normal shift duration.
2. Physical Deformation: Any noticeable swelling, bulging, or cracking on the plastic battery casing. Remove these from service immediately as they pose a safety hazard.
3. Excessive Heat: The battery becomes uncomfortably hot to the touch during normal operation or standard charging cycles.
4. Inconsistent Power: The radio cuts out or restarts unexpectedly, even though the screen indicates there is plenty of charge left.

When managing an event, whether it’s a high-profile corporate gala or a sprawling outdoor music festival, communication is the backbone of your success. If security, catering, and stage management teams cannot communicate clearly, small logistics delays can quickly snowball into major operational issues.

As an official Motorola Silver Channel Partner with decades of experience supplying security and communication gear, Light of Night knows that not all two-way radios are created equal. The physical environment of your venue plays a massive role in how radio waves travel.

Choosing the right walkie-talkies involves understanding the critical differences between indoor and outdoor event spaces and selecting the ideal setup for your team.

Indoor Events: Overcoming Thick Walls & Structural Obstacles

The Challenge: Indoor venues—such as exhibition centres, hotels, stadiums, and warehouses—are packed with physical obstructions. Concrete walls, steel pillars, glass panels, and multiple floors act as barriers that can deflect or degrade radio signals.

What to Look For:

• UHF (Ultra High Frequency) Radios: For indoor use, UHF is king. UHF radio waves operate at a higher frequency, resulting in shorter wavelengths that are incredibly adept at penetrating structural obstacles like concrete, steel, and drywall.
• Compact, Lightweight Designs: Indoor event staff (hospitality, floor managers, and front-of-house security) are often in close proximity to guests. They require compact, discreet radios that fit comfortably on a belt or in a pocket without looking overly bulky.
• Licence-Free vs. Digital Licenced Models: For small, single-room or single-floor events, licence-free models like the Motorola XT420 offer a simple, plug-and-play solution. However, for sprawling indoor arenas or multi-storey venues, powerful digital licenced radios (like the Motorola SL1600 or DP1400) ensure a signal that reaches from the basement to the rafters.

Essential Indoor Accessories:

In enclosed, crowded spaces, broadcasted radio noise can ruin the ambiance or leak sensitive information to guests. Pairing indoor radios with covert earpieces (acoustic tube style) or D-Shape earpieces ensures that communication remains completely private and professional.

Outdoor Events: Maximising Range & Weather Resistance

The Challenge: Outdoor events—such as festivals, sporting events, country fairs, and construction site management—deal with an entirely different set of hurdles. Instead of concrete walls, you are battling vast open distances, unpredictable British weather, and high ambient crowd noise.

What to Look For:

• VHF (Very High Frequency) or High-Power Digital Radios: VHF radio waves feature longer wavelengths that travel further along the earth’s surface, making them excellent for wide-open outdoor spaces with few obstructions. Alternatively, high-power digital licenced radios provide the necessary punch to bridge massive distances.
• Rugged, Weather-Resistant Build: Outdoor equipment takes a beating. Look for heavy-duty handsets with robust ingress protection (IP ratings) against dust and heavy rain. Models like the rugged Motorola R2 or the DP3441e are built to survive the elements and accidental drops.
• Extended Battery Life: Outdoor events often mean long shifts with limited access to mains power. Opting for high-capacity Lithium-ion (Li-ion) batteries ensures your team stays connected from dawn until well after the clean-up crew finishes.

Essential Outdoor Accessories:

Outdoor spaces can get incredibly loud. Equip your team with heavy-duty headsets or high-visibility checkered vests fitted with radio and camera attachments. Utilising multi-unit chargers back at head office ensures that fresh batteries are always ready to swap out when shifts rotate.
