Rated 2 out of 5 by from Disappointed It does what it was designed to do. However, I have several problems with it. First, when I'm only using the headphone jack, my phone's battery is drained at an alarming rate. I have a brand new Iphone, which I assume many people looking at this product are buying it for. If I leave it playing audio through the 3.5mm jack without plugging it in, with the screen off, it drains battery at the same rate as if I were streaming video with the brightness at max. I just feel like it shouldn't use this much power. Second, if I plug it in to a charger with a high wattage, say, a USB-C laptop charger or high-wattage fast charger, it doesn't charge the phone, and the audio coming through the headphone jack has noticeable noise. Third, when using headphones, occasionally there will be some brief static when the adapter gets shifted. Not a dealbreaker, but on top of the other issues, it's annoying and I think it's worth mentioning. Finally, I just don't like the way it looks and feels. I think that it's too bulky, and it doesn't feel as premium as the price should warrant. Overall, I don't recommend this product at this price. If it were a quarter the price, I really wouldn't have minded these issues, but at the price I paid I expected to receive a premium product, and I don't feel that I did.

Rated 1 out of 5 by from Did not charge, 35 mm connection sometimes works Got this to use in my car since it doesn't have Bluetooth. The charger does not work at all. When I connected the 35mm jack to my car it was all crackly, eventually got sound to come through my car speakers, but charger doesn't work. Tried it in the house connected to my charger and I tested the charging cable I use in the car. My cable was fine this adapter was a waste of money. Belkin usually makes better quality products, either I got a bad unit or this one is poorly designed.

Rated 1 out of 5 by from Aux Absolutely terrible, literally lasted a month and then started making a buzzing noise everytime the aux cord was plugged in. Very disappointing after I spent 40 dollars on this product.

is compatible with Dji pocket 3 (via type-c port in pocket 3). I mean connect headphones to one port and a microphone to the other: headphones to the audio input, and a microphone through an adapter to type-c. will this work?

Asked by: AlexP99
Hi, AlexP99. This Belkin adapter provides two ports, turning your phone into a convenient multitasking machine. A USB-C input enables a reliable charge while the 3.5 mm auxiliary port allows you to listen to music, take calls, and more. However, it only allows using headphones with a microphone.
