I have really been impressed by this combo lately.

The xDuoo XP-2Bal plus the PMG Apx. It has 320 mW power so enough for even your most demanding IEMs. What I like about it most is that it preserves the functional ability of a DAP, while allowing your phone to maintain its function of being, well, a phone. Meaning you can tend to phone calls of either business or pleasure while on the go and not be bothered by swapping out of your DAP to carry on a conversation. AND it passes my cardinal test of portable audio in my criteria - it is smaller than a deck of cards.
So you can stow it away in your pocket or fanny pack and not feel like a pregnant marsupial in the pursuit of good tunes. That is there is a built-in microphone that works better than most in its category. There’s also excellent Bluetooth support.
If you were to quantify on a 0 to 100 scale with 0 representing a giveaway airplane variety earphone and 100 being a TOTL DAC, most bluetooth receivers (of which the Fioo BTR7 I’ve been using most recently) get you around a 50; this is closer to 75-80. Especially with the Apx which is incredibly easy to drive. The weight of the bass slam hits you right away - the best way to describe it is that it is like going from a nice set of bookshelf speakers to proper floor drivers. The presence lets you know you are dealing with a big boy amp. Mids are lushly presented and the treble quality is the best Ive heard in bluetooth to date. I almost had to do a double take to make sure I was not listenening to a full size DAP.
One thing it can do that most other smaller DAPs don’t offer is the ability to charge AND play at the same time as it has dual charging and USB inputs and you can get the added audio quality of a wired connection.
Ergonomics are rarely mentioned but when dealing with portable audio these are a must - there is a clearly visible volume/power knob. No power buttons that be jostled if you are on the go. And you don't have to look at it to see if it is on or wait for a display - you head a pleasant click and a blue light shows and you are good to go.
At $160 from Apos Audio it may very well be the best value in portable audio I have ever bought. Normally I do have reservations about recommending kilobuck IEMS or cables because value is hard to defend in such circumstances. But for less than the cost of most TWS sets you can use your favorite IEM/cable combo on the go with minimal fuss and tremendous results.
