    I use this with my iPad mini and and monoaural (old fashioned) earphone. The audio component of this sometimes worked well at first and then only worked intermittently.. The charging component always worked. I switched to new earphones many times but this didn't resolve the problem. These are too expensive to break in such a short time. I recently bought the same adaptor again (no other options) that is is working well. I am trying to be extremely careful about the bending of the flexible cord. Fingers crossed. I theorize that the flexible cord portion is too long and is easily damaged. I would like to see either no cord or a rigid one. The question below asks if I would recommend this product and the answer is yes until there is another option.

    This adapter works well with my Pixel 3 XL, which requires an adapter with an external Digital to Analog Converter (DAC). My main point for improvement is the warranty which is stated to be 2 years. Some competitors offer a 10 year warranty with registered products, and I would like to see a similar option from Belkin. Additionally, the piano black finish is a fingerprint magnet, and I would prefer either a matte finish or anodized metal shell, especially for a product likely to be used in vehicles.

    A good unit with one issue

    This unit works well, allowing use of a headphone stereo plug while charging an iPad. There is one small issue I noticed worth a comment. If used with the original Apple power supply, the unit works properly and allows for charging of the iPad through the unit. However, if used with a generic power supply, especially one with a lower power, the unit does not charge the iPad. This may be why some reviewers say the unit doesn’t work. It appears to need either a higher power supply current (like from an 18 watt Apple charger) or perhaps there is some special protocol required of the power supply. So, just to summarize, it works as advertised with the original Apple charger, but not with other, lower power chargers.

    [Employee of bestbuy] I use this to charge my phone while I play music in my car without a bluetooth radio. It sounds great, only issue is that when no sound is playing there's a slight hiss (which weirdly increases in pitch as the engine revs up) but it goes away when I start playing music. Overall, very satisfied

    YOU HAVE TO PLUG BOTH THE 3.5MM AND USBC TOGETHER

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This is a very niche product. I use it because my vehicle (2013 gmc terrain sle) does not use bluetooth to play music. Newer phones ditch the digital to analog converter as is the case with my new galaxy s23 ultra, so an aux cord with a normal usb c adapter will not work in my car. Luckily this product has a built in dac chip. Plugging both the aux cord and usb cable from my car into this product and then into my phone allows me to play music off my phone through my car and charges it simultaneously. Im sure some people here are trying it with just one of the cables which will never work. This product works fine but loses a star because it is pretty wildly overpriced.

    Works fine, but not worth the price. I'm using this in my car to charge and play audio with a Samsung S21+. Someone using it for more would likely have a better cost analysis. There's a USB C and an aux, not much else to use this piece for. It feels like good quality.

    It works well when using it. I have it in my car to play my music or audio books through my aux in. It plays well when the sound is on, but I’ve noticed that if I don’t leave it hooked up to my phone it has a horrible buz that plays through the speaker. Probably a grounding issue? It may be just my car, but the last model I had didn’t do that.

    It will sometimes send static over the speakers while charging and is very annoying. The sound passthrough still works even when not charging. I think the static may be cause by the charger itself, but I'm not sure. Either way, the device occasionally doesn't do great blocking charger noise.
