The IEM is well made with aluminium enclosure and the cable is good quality Epsilon. It is a very interesting IEM with 4 options of sound signature through switching by a mechanical switch. It has been a great experience for me. So far, I am enjoying the sound signature option in ‘Bass’ setting.

It's been days testing the AAW A3H+ with my old but reliable Lune MKV cable and I'm impressed. Before the A3H (and now the A3H+), I had the Ultimate Ears TripleFi 10Pro and ended up missing the powerful bass from the UETF10P when I stepped up to the A3H but ended up liking the A3H because it was a massive improvement in every other area. That is...until I got the A3H+. This one improves upon the A3H in the mids and lows massively. It's clearer and the bass is definitely way more than I expected. I even had to lower the bass a bit using an Equalizer because it's that much more powerful than A3H's. It'll take a while getting used to these improvements but I do not regret at all getting the A3H+. I now coupled the A3H with the Nyx BT5 cable. Using both units with SpinFit CP145 eartips. I highly recommend it.

Beautiful iem. Have not ready burn in but from first listening, it is quite balanced iem.

Now in my 70's I've traded my audiophile ways in for the convenience of MP3s and flac files played on MP3 players... I realize there's a dropoff in musical info and I can hear the difference, but the convenience takes precedence, so I try to make up for it with using quality players such as Cowon Plenue players and IEMs such as the old Audeo PFE 232 and what had been my most recent phones, the Shure SE535. Having never been satisfied with the Shures but so regretful the Audeos are no longer made, I decided to finally try something from Null..... The A3H has been amazing..... My reaction to its greatest attributes are in the title, SOUNDSTAGE, PUNCH, FIT, WARMTH, AND CLARITY. Soundstage is what hit me first.... Not since my electrostatic days have I been able to experience such a defined soundstage... I'm hearing instruments and their location on the stage like I've not heard before, and discovering instruments I had forgotten were there when I listen to my old standby teest songs from the audiophile days... it's quite startling to hear even from an MP3. Of course the info has to be there in the first place but if it's on the MP3, you'll hear it like never before thru these.... And though I'm not really a bass centric listener as so many are (I concentrate on midrange where voices live), it's amazing how the A3H brings out the punch in drum lines and bass lines without overemphasizing... AS far as fit, I suspect what the A3H does for fit is not unusual for many, but when compared to the way the Shures fit in my ear, I was surprised at how easily these seal while lying flat in the ear.... Love it! And as far as my midrange, where there's where I experience the warmth of vocals and clarity is across the board.... I couldnt' be happier with my purchase... One other attribute I've discovered that differentiates these from my prior phones... It's extraordinarily exciting to hear just how much better these sound the louder you play them... That might sound ...

Came from an 11 year old UE10 TripleFi with the Lune Mark V cable. These have a very different sound signature. Soundstage is definitely clearer and instrument separation is in another league. These don't need that much help from an equalizer like my UE10. This is a keeper and feels (as it sounds) very high quality in your hands.
