About Me:
Came from car audio and am an SPL freak. I use a iFi Micro in "Turbo" mode which is rated at 4000mW @16 ohm. I use the eq's in the images above. I love Hip Hop but am also a big classic rock fan. The Ex1000 are my "go to" set for their ability to play my 2 favorite genre' exceptionally. If you use different gear and different settings your results will be different.
I love bass and I love mids and I love clarity and staging
Bass>>staging>>mids>>clarity in that order.

      + Good bass without amp, responds to EQ great, closer to ASG 2.0 than ASG 2.5, smooth treble even at loud volumes, mmcx connector is common
      - needs a strong amp to achieve truly slamming basshead level bass, stock cable is hideous, bass gets much less refined at basshead levels

Aurisonics ASG-2.5 Impressions

If I were to have one complaint about the Aurisonics ASG-B I reviewed a couple weeks ago, it’s that they lacked clarity and no amount of EQ would be able to get you perfect, sparkling highs. The ASG-2.5, however, includes two balanced armature tweeters in addition to the 14.2mm dynamic driver it uses to produce its incredible bass response. Clarity and detail are excellent, and the tuneable bass port (which, being a basshead, I have fully open) is a welcome addition for those of you who aren’t as into bass as I am.

The ASG-2.5 floats effortlessly between rap, EDM, classical, rock, blues, and every other genre I’ve thrown at them. These are some of the most versatile IEMs I’ve used–as well as some of the most expensive. With their versatility, however, these approach real affordability since I have half a dozen other earphones that serve a more specific genre well (e.g. I use the JVC HA-FXZ200 almost exclusively for bass-heavy but subued electronic music and Pioneer SE-CX8s for hard-hitting rap and EDM). The ASG-2.5 can do virtually anything you want them to.

I rarely talk about audiophile terminology like soundstage, but I have to betray my standard for simplicity by commenting on it with these earphones. The soundstage is out of this world. Listening to a track like Chesky Records’ Jesu, Joy of Man’s Desiring is almost transcendental in its delivery and staging. While I usually drop some of the mid-bass and low-mids to lay the sound back a bit, I actually like to remove my equalizer from the equation entirely listening to the Chesky tracks.

To speak only of the basshead potential of this earphone, it is second to none in its bass depth and ability to cause your chest to rumble and breath to catch. It is only equaled by its bass-player-centric sibling, the ASG-B. Coupled with the ASG-2.5’s ability to shine with nearly all music genres, this could be the end-game basshead IEM for many. It lacks only in bass punch and impact when compared to the Pioneer SE-CX8/SE-CX9, and those only achieve their mind-blowing levels of impact with a proprietary Bass Exciter, so it really isn’t a flaw of the ASG-2.5 to have less raw impact.

If any other company boasts that it has the end-game IEM for bassheads that can challenge the ASG-2.5, I welcome the opportunity to review them (Lear, 1964 Ears, AAW, Tracluent, Sony, JVC, errybody else, I’m lookin’ at you).

No earphone is perfect, so let’s talk about a few of the things I’d criticize.

The mid-bass is a bit bloated and clouds the mids with the bass port fully open. I prefer to have it cut off by ~150Hz for the ultimate basshead experience, so I use EQ to drop the mid-bass and low-mids a bit (see the frequency response graph to see where it’s a bit high).

CAUTION: Don’t use the case they send you. The case that comes with this flagship IEM is inexcusably small. If used, it can actually damage the casing of the earphones. They sent me an extra clamshell case, and I expect Aurisonics to replace the included case in the future (they’ve commented as such, which is great that they’ve listened to customer feedback).

If you are looking at IEMs in this price category, you definitely have a good amp to complement them, right? If you don’t, you shouldn’t consider an earphone at this level until you have a good DAC and Amp to drive them. The ASG-2.5 needs a good amp to sound great, so don’t try driving them directly from your phone or you’re doing these beauties an injustice.

Others often criticize the SureSeal tips as being hard to find a proper seal. I liked them for the ASG-B, but curiously agreed with others for the ASG-2.5 and used double-flange tips instead.

Conclusion: The Aurisonics ASG-2.5 is my current top pick overall for a basshead IEM. It has matchless sub-bass depth, solid impact, and manages to give you the best of both worlds with its dynamic driver providing deep bass and 2x balanced armature tweeters delivering crystal clarity.

Aurisonics ASG-2.5 Frequency Response Graph

This curve was generated using a Dayton Audio EMM-6 Electret Measurement Microphone, Focusrite Scarlett 2i4 audio interface, and Room EQ Wizard. The mic calibration file was provided by Dayton Audio and the output calibration file was generated using the program itself (3.5mm out on PC to 1/4″ input on Scarlett 2i4).

Frequency Response Graph for ASG-2.5 (Bass Fully Open and Bass Fully Closed) and ASG-B

  1. ASG-2.5 Bass Port Fully Open = Red
  2. ASG-2.5 Bass Port Fully Closed = Green
  3. ASG-B = Blue
Quick Notes

  1. ASG-2.5 Bass Port Fully Open (Red) and ASG-B (Blue) are virtually identical up to ~700Hz.
  2. ASG-2.5 Bass Port Fully Open (Red0 and ASG-2.5 Bass Port Fully Closed (Green) become identical after ~1500Hz.

Of all the IEM I've audtioned or owned no others reproduce bass impact quite like Aurisonics ASG-2. While its not completely sub-bass focused ASG-2's like being struck by a world-class boxer behind the forehead. We're talking extreme (over emphasised) impact which strikes you behind the forehead with authority. It also has bass tuning ports which must be adjusted lightly in small increments or you can ruin the presentation. Not even XB1000 from my testing could accomplish what ASG-2 can, and from a tiny IEM.

One of the best things about ASG-2 is due to the adjustable bass ports "you decide" what you want in quantity. And with some fine tuning and sensible approaches they can cater for many peoples preferences due to the bass tuning system.

They were ok, apart from the plasticky housings looking / feeling like they came out of a Kinda Surprise egg. Hippo VB are another popular one but they're really 'all about the bass', without a tremendous amount of care for much else.
