Description
Clear Acoustic Tube Earpiece with In-Line Microphone and PTT
The Purchase Radios PR-AT1 1-wire surveillance earpiece combines a clear coiled acoustic tube with an in-line microphone and push-to-talk control for compatible two-way radios. Choose from nine connector versions to match the exact radio you use. This listing is not one universal headset that connects to every Icom, Motorola or Hytera radio.
At a hotel front desk, retail counter or event entrance, an earpiece lets staff listen to radio traffic at the ear rather than through the radio's loudspeaker. Clip the microphone where it remains accessible, route the cable without pulling it tight and test transmit and receive audio before starting work. The PTT control keeps manual transmission within reach while the radio stays in its carrying position.
The PR-AT1 is a Purchase Radios accessory offered in radio-specific connection options. References to Icom, Motorola and Hytera identify the listed radio applications; they do not identify the earpiece as an OEM accessory made by those radio manufacturers.
Key Features & Benefits
-
Clear acoustic tube: Routes receive audio to the ear for less conspicuous listening than an exposed radio loudspeaker. It is not a guarantee that nearby people cannot hear audio.
-
In-line microphone and PTT: Combines voice pickup and manual push-to-talk operation in one accessible control housing.
-
1-wire layout: A single main cable assembly connects the radio to the microphone/PTT and earpiece components, rather than separate microphone and listening cables at the radio.
-
Nine connector choices: Select the matching PR-AT1 version for your exact radio. Similar-looking plugs and shared brand names do not establish interchangeability.
-
Clothing attachment: Position the microphone and cable so controls remain reachable and clothing does not rub against the microphone.
-
Clear tube and black cable assembly: A practical listening arrangement for hospitality, retail, security and event operations, subject to the needs and rules of the workplace.

Compatibility does not transfer between the nine versions. For example, a Motorola CP200d selection does not establish XPR3300e fit, and a Hytera 2-pin option does not establish HP-series fit. Model names appearing only in tags or filters are not additional verified applications. For intrinsically safe or specialized radios, confirm whether this accessory is part of the required approved complete configuration.

Setup, Wearing and Care
Connect the selected accessory according to the radio's instructions. Seat the connector correctly and use any applicable retention mechanism without forcing it. Keep the microphone clear of clothing and leave enough cable slack for normal head movement without placing tension on the plug or tube.
Before deployment, test listening and transmission with another radio. Start with a low listening volume and raise it only as needed. Press the in-line PTT to transmit and release it to listen. This is not a promise of automatic voice activation, Bluetooth operation or hands-free transmission.
Keep the acoustic tube and ear tip clean and dry. Follow the supplied accessory instructions for removal, cleaning and replacement. Do not immerse the microphone, electrical cable assembly or connector. Do not apply alcohol, solvents or compressed air to the tube or transducer unless the supplier's instructions specifically permit it. Allow any cleaned removable parts to dry fully before reassembly.
For shared-radio teams, identify each user's earpiece or arrange appropriate replacement ear-contact parts. Replace damaged or blocked parts with confirmed compatible components rather than assuming all acoustic tubes and inserts share the same attachment.
Suggested Accessories & Alternative Earpieces
Compare these separately sold earpiece options when choosing an audio accessory for your radio. They are alternatives to the PR-AT1, not attachments for it. Check each product's own compatibility guide; these options do not all fit the same radios.

Motorola PMLN7269ANS IMPRES 2-Wire Surveillance Kit: A black acoustic-tube kit with separate receive-audio and microphone/PTT leads. Its listing includes R5, XPR3300e and XPR3500e applications; confirm your exact radio and supported features before ordering.
-
Motorola PMLN7158A 1-Wire Surveillance Earpiece: An acoustic-tube option with an in-line microphone and PTT for the supported SL and TLK models listed on its page, including SL300, SL7550e and TLK100. It is not a universal Motorola connector option.

Frequently Asked Questions
How do I choose the correct PR-AT1 version?
Match the exact radio model to the selection table, then choose that variant before ordering. For the existing listed applications, CP200d corresponds to PR-AT1-MO-CP1, BD502i to PR-AT1-HY-BD5 and F1000/F2000 to PR-AT1-IC-F1. Ask for confirmation when the model, suffix or specialized configuration differs.
Does one purchase include adapters for all nine radio groups?
No. Each purchased unit is the connector version selected. The nine choices are separate configurations, not a universal adapter kit.
What does 1-wire mean?
It describes the main cable arrangement connecting the radio, in-line microphone/PTT and listening components. It does not mean wireless operation, and it is not the same layout as a two-wire kit with separate microphone and listening leads from the radio connection.
Is this receive-only, or can I transmit?
The PR-AT1 includes an in-line microphone and PTT for transmission with a compatible radio. It is not simply a receive-only 3.5 mm earpiece designed for a remote speaker microphone's listening jack.
Does it transmit automatically when I speak?
Manual push-to-talk is the stated control. Do not assume VOX or automatic transmission unless the exact accessory and radio combination is confirmed to support it and is configured accordingly.
Can I move the same earpiece between different radio brands?
Not simply because they are all portable radios. Choose the appropriate connector variant for each application. Do not force a plug, assume electrical compatibility from appearance or use an unverified adapter.
Can it be worn in either ear?
The original listing identifies left- or right-ear use. Comfort and retention depend on the supplied tip and individual fit. Do not force the tip into the ear or treat one size as suitable for every wearer.
Can I fit an open-ear molded insert?
Confirm the exact insert's attachment and fit with the supplied acoustic tube elbow before ordering. Universal compatibility with every semi-custom insert is not established. An open-ear insert also does not make the assembly certified hearing protection.
What should I check if receive audio becomes weak?
Check the radio volume, correct connector seating and whether the tube is kinked, blocked or contains moisture. Follow the accessory care instructions and use confirmed replacement parts. Do not probe the transducer or use high-pressure air as a general repair method.
Does the earpiece make the radio waterproof or intrinsically safe?
No such claim is made. Radio, accessory and complete-assembly ratings are separate questions. Use only a documented approved combination where environmental or hazardous-location requirements apply.
Are medical-grade materials, Kevlar construction and a temperature range confirmed?
Those earlier claims require supplier documentation for this exact product. This listing does not currently establish a medical-grade or hypoallergenic material certification, specific reinforcement material, microphone element specification or tested operating-temperature range.
