EARPHONE CONNECTION

EARPHONE CONNECTION is a brand of two-way radio audio accessories, primarily earpieces, headsets, and surveillance kits designed for use with Kenwood portable radios. The product line is built around the practical requirements of radio users who need to communicate while keeping their hands free and their radio traffic discreet. The catalog includes earbud-style earpieces, ear hook models, and surveillance kits, each configured with a push-to-talk (PTT) button and either a shirt/lapel microphone or a palm microphone. Connector types include two-pin and multi-pin configurations, matching specific Kenwood radio series such as the NX-340U, NX-3220, NX-3320, NX-3200, TK-3400, TK-2300, TK-5410, and TK-2207. This compatibility mapping is central to the line: each SKU is intended for a defined radio family, so buyers can select an accessory that connects without adapters. The earpieces are available in black or clear finishes, with single-wire or two-wire cabling. Clear earbuds and low-profile wires are typical for surveillance or security work where visible audio equipment is undesirable. Ear hook designs provide an alternative fit for users who prefer an over-the-ear retention style. All models include PTT functionality, allowing transmission directly from the accessory rather than the radio itself. The brand does not publish broad environmental ratings or industrial certifications for these products; the specifications focus on connector type, wire count, microphone placement, and radio compatibility. 3G Electric supplies the EARPHONE CONNECTION line as part of its two-way radio accessories inventory. The current catalog includes 75 SKUs, covering multiple Kenwood radio series and accessory form factors. For procurement and maintenance teams, this means a single source for replacement earpieces, spare surveillance kits, and additional headsets across a mixed fleet of Kenwood radios. Because the products are organized by compatible radio series and connector type, buyers can match existing radio models to the correct accessory without needing to cross-reference third-party compatibility charts. 3G Electric ships globally, serving plant engineers, security supervisors, and operations managers who maintain radio communication systems. The product data provided for each SKU includes MPN, connector type, wire count, microphone type, and compatible radio series, allowing technical evaluation before purchase. This brand profile is intended for buyers who need to specify or replace audio accessories for Kenwood portable radios in environments such as security patrols, event management, warehouse operations, and industrial sites where two-way radio communication is standard practice.

Frequently asked questions

Common questions about EARPHONE CONNECTION from 3G Electric.

What connector types are available in the EARPHONE CONNECTION earpiece line?

EARPHONE CONNECTION earpieces and surveillance kits use two-pin or multi-pin connectors, depending on the model. For example, the EP1201 surveillance kit and the EP201 ear hook earpiece both use a two-pin connector, while the EP4011QR surveillance kit uses a multi-pin connector. The connector type is tied to the compatible Kenwood radio series, so the correct accessory must be selected for the radio in use. Two-pin models cover many TK and NX series radios, while multi-pin models are specified for particular NX series radios such as the NX-3200. Buyers should confirm the radio model and connector type before ordering.

Which Kenwood radio series are supported by EARPHONE CONNECTION surveillance kits?

EARPHONE CONNECTION surveillance kits are listed for specific Kenwood radio series, including the NX-3200, NX-3220, NX-3320, and NX-340U. For instance, the EP4011QR is designed for the NX-3200 series, the EP601 for the NX-3320 series, and the EP1201 for the NX-3220 series. These kits typically include a clear earbud, a microphone (shirt/lapel or palm), and a push-to-talk button. Because compatibility is series-specific, the radio model should be matched to the kit's stated compatible series. The product data for each SKU lists the exact radio series, allowing verification before purchase.

What is the difference between the EP201 and EP301 earpieces from EARPHONE CONNECTION?

The EP201 and EP301 are both ear hook earpieces with a shirt/lapel microphone, push-to-talk button, and a single black wire. The primary difference is the compatible radio series: the EP201 is specified for the Kenwood TK-3400 series, while the EP301 is specified for the TK-2207 series. Both use a two-pin connector. Physical form factor and wiring are otherwise similar. Selection should be based on the radio model in use, as the connector and internal wiring are matched to the radio series. Neither model is listed with environmental ratings or additional certifications.

Are clear earbuds available in the EARPHONE CONNECTION range?

Yes. Several EARPHONE CONNECTION models feature clear earbuds, including the EP1201 (for NX-3220), EP1301 (for TK-5410), and EP4011QR (for NX-3200). Clear earbuds are typically chosen for surveillance or security applications where a visible earpiece is not desired. These models also include a microphone and push-to-talk function. The clear earbud is combined with either a single-wire or two-wire cable, depending on the model. For example, the EP1301 uses a single wire, while the EP4011QR uses two wires and a palm microphone. Buyers should confirm the wire count and microphone type against operational requirements.

Does EARPHONE CONNECTION offer earpieces with palm microphones?

The EARPHONE CONNECTION line includes at least one model with a palm microphone: the EP4011QR surveillance kit. This model is designed for the Kenwood NX-3200 series and features a clear earbud, two wires, a palm microphone, and push-to-talk functionality. A palm microphone allows the user to hold the microphone near the mouth for transmission, which can be useful in high-noise environments. Most other models in the line use a shirt/lapel microphone. The EP4011QR uses a multi-pin connector, unlike the two-pin connectors found on many other EARPHONE CONNECTION earpieces.

How can I identify the correct EARPHONE CONNECTION accessory for my Kenwood radio?

Match the radio model to the compatible radio series listed for each EARPHONE CONNECTION SKU. For example, if you have a Kenwood NX-340U, the EP1201 is listed for that series. If you have a TK-2300, the EP6501MS-B is specified. The product data includes the compatible radio series, connector type, wire count, and microphone type. Because connector types vary (two-pin vs. multi-pin), selecting by radio series is the most reliable method. 3G Electric provides this data for each SKU to support specification and procurement. If the radio model is not listed, an alternative accessory may not be compatible without an adapter.
