Listen-Only Mono Earphone with 3.5mm Connector Plug

Discrete Audio Monitoring for High-Noise Commercial Environments

Secure your radio communications and monitor incoming audio privately without letting nearby civilians hear sensitive fleet traffic.

The genuine Icom SP40 is a commercial-grade Icom SP40 Listen-Only Earphone for Icom HM-222 engineered to deliver clear, clear-cut incoming audio transmissions directly to the user's ear. Deploying the Icom SP40 into your operational layout ensures that sensitive operational dispatches remain completely confidential. This lightweight receive-only assembly comes standard with a universal 2-conductor interface plug that fastens directly into standard auxiliary audio output ports.

Specially built for event security teams, medical personnel, hospitality staff, and manufacturing floor workers, the Icom SP40 resolves the frequent workplace issue of missing urgent calls in high-noise zones or disrupting quiet public areas. Utilizing this discrete, low-profile earbud allows field operators to stay connected to dispatch lines while maintaining hands-free mobility and complete environmental awareness. The earpiece kit includes alternative soft cushion inserts to accommodate different ear shapes for continuous multi-hour shifts.

The durable wire routing is sheathed in a highly flexible polymer insulation layer designed to resist daily stretching, sweat accumulation, and environmental wear. When removing or stowing the equipment after duty cycles, operators should actively avoid pulling or wrenching the thin wire line directly from the earplug housing to protect the internal copper filaments from mechanical micro-fractures.

Did not disappoint!
Perfect Fit: Bolted right up to the engine block without any shimmying or modification needed. ​Strong Crank: The motor sounds powerful and turns the engine over significantly faster than my old, dying unit. Once hooked up, the car fired up instantly on the first turn of the key. No grinding, no clicking, just a smooth, high-torque start. Price: A lot more cheaper then your average auto parts stores. ​Build Quality: The solenoid connections are solid and the threads were clean. Packaging: The box arrived on time but a bit beat up, but the starter itself was well-protected in bubble wrap and undamaged.

Still working great!!
I really didn't have a good feeling about ordering a starter online, but I was in a situation where I didn't have the time to get to the auto shop before my day off and Amazon could get me this part just in time. So I reluctantly gave it a shot. When it showed up it had a couple of small black pieces of plastic loose in the box similar to the pieces shown in another review on here. It didn't look like they from anything functional. I really needed to get my wife's car running so decided to install it anyways. The install was easy and it was a perfect fit. The only draw back would be that the signal wire didn't click in place like the signal wire on the original starter. But it was a snug fit. It has been installed and working great for a month now. Very happy with my purchase. It also had a message from the seller when I opened the box giving the starter a 2 year warranty. Very cool. If the starters fails in the next two years I'll get on here and edit my review. So if your reading this then it is still working great.

Great quality at a great price too!
Husband got this for his ‘05 Camry and says it looks and fits just like the original. He was happy that it simply slid in with no adjustments needed. It’s been a couple months now and no problems at all. Very satisfied with this item.

Electrically good. Fitment not so good.
This starter worked fine when installed. The only reason I didn't give it a 5 star rating was fitment. the hole in the bell housing is slightly larger than the starter. The old starter, OEM, was a right fit. This puts all of the strain and torque of starting the engine on the two bolts that hold the starter in. I expect this to fail at some, hopefully, distant point in the car's future. In order to retorque the starter bolts, the battery and airbox have to be removed.
