Chassis Ears Automotive Engine Noise Finder, 6 Channel Car Sound Detector Tester Tool Set, Electronic Stethoscope Diagnostic Kit with Headphones

This tool is extremely helpful in diagnosing noise concerns on vehicles. It's easy to setup and use. The tool is basically a stethoscope that can be attached to different parts. There's 6 channels that can be switched between using a knob. The intensity is measured using lights on a meter. Basically the channel with the highest reading is your most likely issue. Keep in mind to stay away from rotating assemblies, obviously.

The KTTOOL Chassis Ears Automotive Engine Noise Tool worked exactly as advertised and saved me a ton of guesswork. I used it to track down a driveline noise on my WRX STI, and it pinpointed the source quickly and accurately. The setup was straightforward—the clips are solid, the cables are long enough to reach where you need them, and the sound feedback through the headphones is clear. It really helps isolate noises that are otherwise impossible to track down by ear while driving. This tool paid for itself in just one use. Instead of throwing parts at the problem, I was able to confirm the exact source of the noise and move straight to the fix. For DIY mechanics or professionals, this is a must-have diagnostic tool.

Initial review-bench test, it does work but very noticeable variances in mic sensetivity, this shouldn't affect effectiveness will update if it does

Great tool. I swore I had a front end issue… wheel out of balance, strut shot, break rotor warped or out of balance… something just had to be wrong with the passenger side front wheel! Then I got this microphone system… within an hour I pinpointed my transmission. Torque converter going out (by from driver’s seat my ears told me it was the passenger front wheel)… microphone system showed passenger and driver wheels equally noisy, and the microphones I put near the transmission were off the scale. Wish I could tell you there was a happy ending… maybe there was… I added some shudder stop to the transmission and traded the truck in. I think the microphones paid for themselves ten times over.

This thing is so cheap. I push on the battery door and try to move it forward and it won't open. I'm afraid it might break if I push any harder. Very disappointed. Returning.

It works. You get 3 harness with short wires and 3 with long wires.

Great tool finds noise quickly.. Easy to setup and use..

I purchased this kit because I was tired of the shop kit never working when I needed it. I must say the price was very reasonable. I've used this kit several times and although it is somewhat cheaply made it does actually work. I've been able to diagnose several noise issues at work using this kit. I don't recommend loaning it out to others based on how fragile some of the components might be but if you take care of it then it will take care of you.
