dB MAGIX AC1 MFi Certified Hi-Fi Lightning Headphone Mini Amp (Exceptional Sound from APE/FLAC/WAV Playback for Music Lovers) Lightning to 3.5mm with Charge Port for iPhone X iPhone 8 iPhone 7 (Black)

The unit works great as a headphone / lightning splitter: no issue at all charging phone using a variety of sources (apple's own / USB from my PC / USB on flight / cigarette in car) and all of my wire headphone works great with this unit. Once boosted with the app, sound level improves across the board with some noticeable improvement in mid-range as far as I can tell.Recently amazon dropped it price from £59.99 to £35.99 which is the main reason I picked this unit instead of other simple adapters; effectively i get an amp with some sound improvement for an extra £25 which to me is an OK price to pay / invest in.Knock 1 star off primarily for 2 reasons: 1) the build which is a bit flimsy especially the button that releases the lightning cable and 2) for anyone using it in a car you should test it carefully: mine works fine with a USB cigarette lighter adapter however if i use it with the in-car USB port which support phone book / call functionality, it would randomly stop my music while its playing which is really really annoying. I need to spend some more time to identify the cause was but i am really puzzled so far as phone call functionality were not affected in anyway and using my phone for GPS has no issues either, just the music playing got randomly stopped.

Excellent device. Dramatically improves sound on headphones and any audio equipment connected to it, provided you install the dBMagix "SoundWise" app (from the App Store) and turn boost on. I recently upgraded to an iPhone 8, which requires a 3.5mm/lightning adaptor for old-style headphones. Apple supply one with the phone, a flimsy affair which doesn't look like it will last long. This device is so much better, and charges the phone as well. My iPhone 8 has much clearer audio than my previous iPhone 6, so with this adaptor I'm very happy with the result. Highly recommended.

This is a really good product. I bought it not because I needed a headphone amplifier (I own the rather sensitive Sennheiser Momentum 2) but rather because I felt I would get a purer sound from the lightning socket rather than the headphone jack. Indeed this is correct and the amp also adds a lot of presence in the treble. I wouldn’t say it is transparent but it certainly add enjoyment when listening to Apple Music etc.
