zoyuzan Compatible for iPhone Headphone Adapter 3.5mm AUX Audio Jack Charger Dongle Earphone Splitter Compatible with Lightning Male to USB Female OTG Power Charging Camera MIDI Connector for ipad

So I bought this adapter to connect a digital piano to my phone so that I could use a various piano apps (especially Simply piano). This device works perfectly. I can connect and play with headphones, staying quest for the rest of the house and knowing that each key/note is being registered in the app. I also was able to use an “Aux” cable to connect the phone/app audio through the piano. Love this as I can practice with that “live” feeling. Value- check, easy to use - check.

Compact

Mine worked beautifully for several weeks. Then it ceased functioning. I bought a second, thinking perhaps the first was defective. It wasn’t. The unit is a piece of garbage - unreliable and, ultimately, an aggravating experience.

If you’re shopping for this, let me get this out of the way. Yes, it works! USB works. Headphone out works. Charging works. My only caveat is that since there is a little DAC/AMP in here, it’s not the best quality DAC/AMP. You’ll get about 80-85% of the volume and you’ll notice a boost in the lower to low-mid frequency ranges (so it sounds a bit bloated) from what you’ll get out of an Apple lightning to 3.5mm adapter but it should be more than sufficient. Lastly, the unit genuinely feels like it’s lighter than the sum of it’s parts but I don’t feel like it’ll fall apart on me. Overall, it works for what I needed it for.

All was good as expected

Stopped working after a while :(

Works well. Exactly what I needed. Would buy again.

I used it for connecting to iPad Pro for midi and audio. Unfortunately, the midi kept disconnecting with any small movement or vibration.
