Apple Certified for iPhone Headphone Adapter 3.5mm AUX Audio Jack and Charger Extender Dongle Earphone Headset Converter Lightning Male to USB Female OTG Cable Camera Memory Connector Kit Splitter

This is a magical little adapter! But it does have a couple quirks. I recently acquired an Akai MPK Mini Mk3 and I simply wanted to use my iPhone 11 as a lightweight mobile workstation with GarageBand, Bandlab, among other MIDI controller apps and DAWs. While lots of people use these adapters with iPads in recording setups, I'm working on a budget as well as trying to make my setup the most portable and lightweight it can be. This adapter is perfect for the job. I found the secret to this adapter is that having a lightning power source plugged into it will not only charge my iPhone while using a midi controller, but it will also power several other devices via a 4-port USB hub, without the need for a hub that has its own power supply. As far as I can tell, the lightning port on the adapter will only charge the device and will not transmit data or audio. While I would still recommend getting a powered USB hub with it's own AC power supply for very power hungry devices if you intend to use it this way, the lightning connection on this adapter does in my case seem to eliminate the need for a powered hub with an MPK Mini. PLEASE TAKE NOTE: While the audio port works well with headphones and headsets, the one bizarre issue I have is that the audio port ONLY works with a headset or regular stereo headphones, and NOT a stereo aux cable, for whatever reason...? I wanted to use the port as a line out for an amplifier/speakers but it simply would not work at all, I tried multiple 3.5mm cables. The adapter's audio jack itself still works well with headsets, I have confirmed it is a 4 pole TRRS jack for headsets with inline microphone/volume controls, it works with live monitoring in GarageBand. Perhaps I simply received a flawed unit, but having tested the adapter with multiple cables and different speakers and not being able to figure this issue out, I simply ended up purchasing a USB soundcard with two separate TRS stereo audio/mic ports for use with a hub, which works equally as well and is much simpler. Again, the adapter does work well WITH HEADPHONES and otherwise flawlessly, but it doesn't work as a typical line out jack should.

Works well connecting my yamaha digital piano to my ipad.

The headset would not connect. Then it briefly connected then switched off and started playing out of the phone speakers. Tried it multiple times and would not play using headset, hardly connected at all and then when it did connect it quickly disconnected. I had to coax it to charge the phone because at first I would not connect to charging but eventually it started charging. Very disappointed in the quality.

It works perfectly

I guess it was okay! It just wouldn’t fit my iPhone!

Works really well, but it recently almost fully stopped working and I’ve only had it for a few months. It works when I shift it around a bit in my phone, but it only works on one side, and recently if I even put my phone down, it’ll stop working

bought this to use with an iphone X for several purposes: 1.) to power and run a zoom h2n field recorder (im a video game sound designer/composer of 15 years) and it works great for a super lightweight field recording setup using an iphone (much easier to edit/review recordings using the 'multitrack daw' ios app, than the h2n's firmware). fun fact: i can actually power my h2n as well as a korg nanokontrol using a usb Y splitter into this adapter. 2.) i bought this to use the iphone X for live music performances (am also a performing artist of 20 years). as mentioned above, using a usb hub, you can power multiple devices (depending on their power draw). the analog audio out on this adapter worked great when running into a large sound system using a hosa 1/8" stereo -to- 1/4" split cable. obviously the audio out works great into headphones. i tried an old irig interface (stereo out, mono 1/4" input) plugged into the audio jack on this adapter and i was able to run a guitar into drambo app, however there was a very distinctive hum in a perfect key of B (might be nice to record t hat into a sampler and play it on the keyboard) so that's maybe not the best use for this adapter, however a headset (3 ringed 1/8th" jack) into this adpater would probably work just fine for facetime calls etc.

This aux adapter is terrible. I purchased it October 16 and it doesn’t work. I have not used this thing 10 times. This is extremely frustrating
