Fits all handsfree with cord
Hinged ferrites that absorb the HF energy and minimize the crossover between the mobile phone and the hands-free cable. They are sold in pairs and one is mounted at the connector and the other under the microphone.
Especially recommended for IPhones, as they have more radiation from the hands-free cord.
Weight for 2 pcs is 12 grams. External length 25mm, diameter 15mm each.
Can be opened with a small screwdriver.
Fits all cables with a diameter up to 3mm.
