EARPHONE CONNECTION
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.
