    • I bought 2
I trust the Belkin brand. I bought 2 of them and straight outta the box one of them wasn't working properly. Plug in the 3.5 and it works. Plug in the power and it stops charging my phone and cuts off the music! Please help me to rectify this issue. I'll be checking out the other one tomorrow. I am really under the weather and want to connect my head to some music and fall asleep! Sincerely, John Houser ... show more

    • Stopped working after 8 weeks; another unreliable splitter from Belkin.
Worked for 8 weeks, then the audio port failed. I tested all of the wires and it was indeed the Belkin unit that was bad. This happened once before with the lightning version of the same splitter. I mean, Belkin, COME ON. Be better than the unbranded crap from China. I'm not paying a quarter of a hundred dollars for something that lasts less than two months. ... show more

    • Listen and fast charge at the same time
I bought this because most new phones don't have a 3.5mm headphone port. But I wanted to be able to listen to calls or music, and also charge the phone at the same time. This device can do that. Or, just use it to listen with headphones. One or both ports can be used at a time. Audio quality is good to my non-audiophile ear. It's not hollow sounding with a good pair of headphones. Digital-Analog Converter (DAC) chips have come a long way in recent years, and are now part of everyday devices. There is a very quiet "hiss" sound between when audio track/sound ends and before the DAC in the adapter shuts off when there's no noise. You'd have to be in a very quiet room to notice it, and it's not an issue for me. Volume is adjusted through the phone's volume control menu, just like with normal listening or calls. Overall it's a great device for modern phones, you can listen and fast charge at the same time. I'm impressed! ... show more

    • 5/5; it is my go-to as a necessity

Functionality: 5/5 Functions as intended with no issues since I've purchased it. Durability: 3/5 Has a plastic shell, so I would not advise being rough with the product in terms of tossing it around, yanking it off from the phone, etc. Treat it with care and it'll last long. Connection speed: 5/5 No indication of lag when connected to my Apple earphones and Anker charging cable. Charging ability: 5:5 No indication of slow charging. Charging speed seems to be about the same without this connector and just having my phone plugged directly to the charging cable. Heat level: 5/5 At most it gets warm Compatibility: 5/5 No issues connecting to the Apple 3.5mm earphones and Anker USB-C to USB-A charging cable Extra info: I previously used this version of the product for my iPhone 11 pro that had the lightning cable, and also had no issues with it. ... show more

    • Heats up easily, doesn't work with USB-C to USB-A even in own brand
Review Image by Sami Genstein Sami Genstein
Review Image by Sami Genstein Sami Genstein
I should have sifted through the reviews more. This adapter doesn't work with its own brand of USB-C to USB-A cords, which was the main thing I wanted it for. Please note the Not Charging alert. It can work with USB-C to USB-C, but my main goal was to have a long cord that didn't require using the huge, chunky adapter Apple offers with the iPad Mini Pro. I'm going to give it a bit more of a try, but I'll likely return it due to having a poor transformer and compatibility issues. I'm disappointed, Belkin. Your similar adapter that works with lightning cables is far better. Why did you change the form factor? ... show more

    • Buy once, cry once
It might seem expensive, but if you have an old car but a new phone, then this is the solution you need because you can charge your phone and output to your AUX all via your USB-C (there is a lightening version available too). I tried cheaper variants before this which didn't last or wouldn't charge properly so eventually I paid up for the Belkin and it's been working like a charm. I took off one start because, as good as it is, it feels like a lot of money for a tiny dongle. Lastly, my set-up is: Cigarette charge with usb-c port --> USB C cable to the Belkin dongle, 3.5mm stereo cable from Belkin dongle to AUX on stereo, USB C connector on dongle to Iphone ... show more

    • Marvelous!
Excellent gadget. Saved me hundreds of dollars. My 2005 truck only has an AUX input port and that stopped working when my new phone came without a 3.5mm phone jack. Bluetooth does not work with my old radio. In order to get Bluetooth connectivity, I would have had to install a new radio and matching speakers. I could have purchased a Bluetooth adapter to connect the 3.5mm AUX plug into the AUX input, but reading reviews on alternative Bluetooth dongle adapters, convinced me that there are volume and noise problems. I just tried the Belkin RockStar™ 3.5mm Audio with USB-C Charge Adaptor plugged into my AUX in jack and it is providing excellent results. I can make and receive phone calls and the cell phone charges just fine. Streaming music is static free. Liking this solution the best. Pros: It works with the phone set at low to mid volume. Works with my antiquated radio and amplifier. Excellent sound. I would buy another one to replace it should it ever fail in the future. I would recommend it to friends and strangers. Cons: Not free, but a reasonable price. DISCLAIMER: This review was not generated using AI, nor was it part of any sponsored promotion. I'm just a regular guy trying to save a few bucks. ... show more

    • Not fit for purpose. Can’t use for phone!
Not fit for purpose. The purpose is for use in my 1995 car. I use an adaptor that connects to my cassette deck by way of an audio jack. I also need to keep my phone charged using a USB-C cord. I did not have a problem with both music and phone audio using the previous version of this same product, but that product began to fail, so I bought this to replace the same exact product. However, with this new version of the same product, I can only use it for music — not for phone calls! Totally useless for me. I don’t understand how the same product gives me a different result. ... show more
