Best Audio Interfaces for iPhone
The iPhone connector is only half the story. A microphone may need phantom power, a guitar needs an instrument input, and some interfaces draw more power than a phone can reliably supply. Decide what you are plugging in first; then check whether your exact iPhone has Lightning or USB-C and what cable comes in the box.
For one XLR mic or guitar, I'd start with the iRig Pro I/O. The iRig HD 2 is simpler for guitar alone, while Pre HD is the mic specialist. A desktop Scarlett can work with supported iOS devices, but its power and cable setup makes it a less carefree phone purchase.

Best flexible iPhone inputIK Multimedia iRig Pro I/O
I would take the iRig Pro I/O when the same small kit must handle an XLR microphone one day and a guitar the next. IK documents a combo input, headphone monitoring and MIDI, with Lightning and USB-C cable options for supported devices.
Its versatility puts it first, but the connector is one analog channel, not separate mic and guitar tracks. On a phone, two AA batteries or the specified supply may be needed for power and phantom use. If you only plug in a guitar, the less complex HD 2 is easier to carry.

What I like
+Combo input, monitoring and mobile cable options.
What to weigh
−Power setup and single-channel limit need planning.
- Inputs
- 1 × XLR / Hi-Z combo
- Conversion
- Up to 24-bit / 96 kHz

- 2 AA or specified optional supply for iOS

02 — IK Multimedia
Best dedicated guitar interfaceIK Multimedia iRig HD 2
The iRig HD 2 is the one I would buy for an electric guitar and a supported iPhone. IK specifies a quarter-inch instrument input, headphone jack and switchable amplifier output, so practicing silently and feeding an amp are both defined uses.
It ranks second for flexibility because there is no XLR microphone input. The current maker package lists Lightning, USB-A and USB-C cables; still confirm the exact box and your phone. For guitar only, its simpler path may be a better buy than the higher-ranked all-rounder.

03 — IK Multimedia
Best for one XLR microphoneIK Multimedia iRig Pre HD
I would choose Pre HD for a reporter or singer who needs to connect one XLR microphone to an iPhone. Its direct headphone monitoring and gain control make the microphone path clearer than trying to adapt a guitar-only interface.
It is third because it will not take a guitar directly, and 48V phantom power requires two AA batteries. Check whether the linked package supplies the cable for your Lightning or USB-C phone. If you swap between mic and instrument, pay for the Pro I/O instead.

What I like
+Dedicated mic path with direct monitoring.

04 — Focusrite
Best shared phone-and-desk interfaceFocusrite Scarlett Solo 4th Gen
The Scarlett Solo is the studio-desk choice here if you also record on a computer: one mic preamp, one instrument input and proper monitor outputs make it more useful at home than the pocket devices. Focusrite lists iOS compatibility for the fourth generation.
I leave it fourth for an iPhone-first guide because bus power is the hard part. Focusrite says some iPhones cannot power an interface from a direct connection. Confirm the exact phone, cable and powered-hub arrangement before buying it for mobile work; choose an iRig for a simpler bag.

- 1 mic, 1 line/instrument

05 — KYXAIN
Best low-cost experimentPocket guitar audio interface
This pocket interface is the inexpensive way to see whether recording a direct guitar signal on a phone suits you. Its exact listing is built around a guitar connection rather than an XLR microphone or multiple sources.
I place it fifth for a narrow budget experiment. The listing gives much less dependable detail about iPhone generations, power and monitoring than IK does. Check the connector and your recording app before ordering; spend more on the HD 2 when the phone is part of a regular practice routine.

FAQ — Audio Interfaces for iPhone
01Will a USB-C connector guarantee iPhone compatibility?+
No. Check the interface maker’s iOS support, cable and power requirements. Focusrite warns that some iPhones cannot power a bus-powered interface directly.
02Do I need phantom power?+
Only for a microphone that requires it. IK specifies battery or external-power requirements for its iRig Pro I/O and Pre HD when supplying 48V; an ordinary dynamic mic does not need phantom power.
03Can one interface record a mic and guitar at once?+
Not if its XLR and instrument connections share one input channel. The iRig Pro I/O records one analog source at a time; count independent channels before planning a duet.
The short answer
Start with the IK Multimedia iRig Pro I/O.
I recommend it for one mobile recording kit for mic, guitar and midi at different times. Choose something else if you need two independent analog inputs simultaneously.
