To solve it, just keep the phone away from the cable. This is a fairly common issue, although this is the first time I've heard it happen with amplified signals (it usually happens with line level signals because they are much weaker, so the ratio of EMI to signal is much greater). It seems the antennae are located in the upper part of the phone, so the effect is the strongest when the top is close to the cable. When it's near the cable, the radio waves emitted by the antennae induce into the cable and create audible interference. This is how it connects to Wi-fi, Bluetooth, GSM, GPS, and any other wireless services. The phone has several radio antennae in it. If you disagree with something, please use language that orients others to problems or alternative perspectives, not language that evaluates or attacks others' knowledge. Read about why this separation exists here. Here you can ask which headphone is better, which amp you should buy, which gear best fit your budget and anything related to headphone comparisons and purchasing.įilter by Flair Full-size Open HPs Full-size Closed HPs IEMs Wireless & Portable HPs Amplifiers DACs Sources Rules
