       | 
       | The best audio player is the one you have in your hand right now.
       | (to butcher the quote) And that for me, just like my camera, is
       | the phone that is always there.
       | 
       | Having said that Music, like coffee, or keyboards is a very
       | personal thing that people connect with and so I can see the
       | appeal of the focused device. It's similar to the e-book reader I
       | suppose where there are not the distractions of a full connected
       | phone. Just you and the music.

         | the audio quality worth the effort. Several types of headphones
         | simply can't be driven by most phones directly.
         | 
         | I've even gone as far as using my phone's OTG USB feature to
         | hook up my amp as a DAC, which is admittedly awkward in my
         | pocket. But to your point, I would miss my convenient streaming
         | options.
         | 
         | A good compromise are amps that use a high quality bluetooth
         | connections, like EarStudio.

         | Depending on the headphone the biggest problem is the amp not
         | the DAC. E.g. something like a hifiman Sundara or a Sennheiser
         | HD 600 Series requires a bit more power then a cell phone
         | typically requires. Looking at the specs for the M3k it looks
         | to me that it is not really suitable for these kind of
         | headphones. I like using slightly bigger mobile amps with the
         | Sundara. Used to have a Topping NX4, which worked well, but
         | died after 6 months, now switched to an ifi hip-dac.

           | 
           | just a sidenote: the sundara you mention have 37 ohm which is
           | pretty standard and they should be easy to drive.

       | The most glaring omission is the built in player has no concept

       | one.
       | 
       | Other complaints are that they advertise Airplay compatibility

           | That usually means one of two things--
           | 
           | 1. the frequency response of this new system is different,
           | changing the relative loudness of different instruments;
           | 
           | 2. the context caused you to concentrate on the music
           | differently and your experience of it was therefore
           | different.
           |
