Iphone Shows Headphones Connected All The Time

Connected to my iPhone and it just worked.

2/3 of a stop is a good value for my needs. the full stop was too much and 1/3 not enough at all.

Before I bought this amplifier, I would have to connect my headphones (Sennheiser HD201 and eH350) to my desktop speaker's headphone output each time I wanted to use them (late at night, for example). In order to get roughly the same listening volume through my headphones, I'd have to really crank up the volume knob on my speakers (they take a lot of power compared to your typical earbuds). With the HA400, I can keep my headphones and speakers connected all the time. When I want to use my headphones, I just turn down the volume control for the port my speakers are connected to and turn up the volume for my headphones (and vice versa to use the speakers again). This amplifier really lets me enjoy my headphones. The amplifier seems really well built and solid. The input/outputs are all 1/4 stereo connectors (could be a con for some, but I have a bunch of 1/4-1/8 adapters already, so it's not a problem for me). The only thing that I feel it's really lacking is a power switch, but in reality, that's not a big deal to me. All in all, I highly recommend.

Connected my old amplifier and was able to hear my music from the iPhone, no hustles.

I bought this a month ago. I think it's something that should have come with the iPhone 7 as you can't charge and use headphones at the same time. I recently travelled and used it to charge my phone and watched videos the whole 7 hours. It was great - arrived at my destination with 100% charge.

I have owned the Shure SE425 in-ear headphones and the SE535 for some time now. I love the clear and non-bassy reproduction of the Shure SE425, on my iPhone 6s especially in conjunction with the in-line remote/mic cable. In conjunction with the Bluetooth 5.0 Communication Cable, the bass is much more pronounced, almost too much for me! The Shure SE535 headphones sounds warmer, the frequency response may score better in tests, but in conjunction with my iPhone, I prefer the SE425. However, things are different when pairing my Android phone with a DAC headphone amplifier: Here, the Shure SE535 headphones clearly show their strengths compared to the SE425.

Helpful to pass time while on public transit. I can listen to music on my iPhone with headphones since there's no more audio jack on phones. Well-designed and works perfectly.

I use it to connect my wired headphones to my new iPhone. Works great!

The watch is a useful companion to my iPhone. Set up was easy and within a few minutes it was connected and functional.

I plugged it in the aux jack in my old Honda, connected it to my iPhone and it works perfectly.
