Headphone Amp For Iphone 4

My first headphone amp purchase; purchased for use with Grado 225i paired with Bluetooth + iPhone. The 225i doesn't require much power to being with, but even I, not being an especially adroit at HiFi tech, easily discerned enhanced performance with the FiiO. Ordering online with B&H was easy and delivery was on time. Solid experience!

A rare find. Not too long; good use for a headphone amp.

Mic, Pre-Amp, and Headphone Amp in an all-in-one package! Nice to be able to use a USB mic without the need for a separate pre-amp. Really like the headphone jack incorporated into the unit with separate gain controls for the headphone volume.

Great for iPhone and iPad. I wish it had a headphone output.

If you use the apple headphone adapter, you can also use it with iPhone X

needed it for an iphone w/o the headphone jack

I use this cable to connect dac to headphone amp. Works flawlessly.

I use to as a headphone interface to a guitar tube amp DI out. It works great for that.

We're a voice-over studio and it helps to have a clean headphone feed...and this little amp shines. It was a rocky start as the first one arrived with no left channel and a terrible hum. A call to B&H and a replacement arrived quickly. The second one is low-noise, has plenty of power, and the price is right.

It does what it's supposed to, a nice lil' headphone amp for home recording. As with most Presonus gear... good construction/design, quality components and great pricing. Separate monitor level and mute plus mono switch nice touches. So are the 1/3 rack space size and pre-threaded bottom plate for mounting. Relatively clean and powerful.
