Driven by a desire to try out a Hybrid configuration IEM, and hearing good praise for the ASG-1PLUS from ears I trust, when I spotted an opportunity to get them for cheap used, I jumped on it, after a couple weeks living with the IEM, I have to say I don't regret this decision at all. This is despite me not having any liking for "basshead" signatures, which Aurisonics/Fender has been known for.
Build/Accessories:
The ASG1-PLUS is a hybrid IEM featuring a 14.2mm Dynamic Driver (sidenote: Why don't more IEM manufactuers use big dynamics these days?) complimented by a Balanced Armature tweeter for the highs. The shells are made of acrylic and appear to be of high quality, while the red "AS" lettering on black shells is a nice, understated look that doesn't appear overly obvious, which is a welcome respite given some of the IEM designs cropping up in the past years.
The cables use a 2-pin connector system, which I am not particularly fond of due to its fragility, the cables themselves are nicely braided, with a memory wire section (which I personally don't mind, but YMMV) and a thoughtfully designed y-splitter. Unfortunately, the 2-pin connector on my left earpiece appears to be somewhat recessed for some reason, which is concerning for long term use (shown in picture below).
The accessories for the IEM include:
- 4 pairs of Aurisonics tips (S, M, M+, L)
- 1 cleaning tool
- 1 hard plastic box to store them in when not in use
I can't comment on the box, as it did not come with my used copy, the tips supplied by Aurisonics did not work well with my ears, while they are made of silicon like everyone else's, the silicon they use has a different texture and irritated my ear canals, luckily, with some elbow grease, I managed to fit the silicon tips supplied with the MEE P1 over the wide nozzles, which would be the basis for the sound evaluations later on.
Ergonomics/Usability
The housings are made in a CIEM-style design that has been catching on nowadays, with a deep but not wide housing that sticks out of my ears a little. I have fairly small ears, so with the housings stuck in the concha area as they should be, it's not the most comfortable, but it's not egregiously uncomfortable either. The memory wire section does not conform very well to my ears, but it approximates it well enough that I don't have significant issues with it.
The good news is that with this sort of style, isolation is top notch, noticeably better than other over-ear style IEMs like the MEE P1 and Westone W40.
Sound
I honestly wasn't sure what I was gonna get with this pair of IEMs soundwise, I had seen from reviews that these are supposed to be the "neutral" sibling of the ASG lineup, but was not sure what that meant, given the reputation for Aurisonics as a purveyor of basshead IEMs. What I found was a pleasant surprise, a signature that does not stray too far from neutral while still being highly enjoyable for non-critical listening sessions. All listening and comparisons were done on the Hifiman HM650 (Balanced)
Bass:
Very nicely done, while there is some emphasis in this area to my ears, it's not to the point where it's bloated and interferes with the overall presentation. The emphasis is most heard in the subbass, with basslines being presented in a relatively forward manner and plenty of audible, powerful-sounding rumble, this, to me is a very suitable tuning decision, as for outdoor use, subbass may be drowned out more easily by background noise. The mid and upper bass also slam with plenty of weight and texture, in a unique way that can only be found with large, dynamic driver IEMs, of course, the drawback to this is that the bass isn't gonna compete speedwise with BAs, but for me, the presentation was too enjoyable to nitpick.
Mids:
The mids of the ASG-1Plus can be described with one word: Lush. From the lower mids onwards, notes are presented in a rich, thick manner, but not to the point of impeding detail retreival, the lushness manifests itself in perceived warmth with male and female vocals, upper mids are slightly dipped from what might be strictly neutral, but not in a manner that makes female vocals overly distant. I don't detect any coherency issues between the bass and mids, which has been a concern with many hybrid IEMs.
Treble:
The treble is well extended, relatively speaking for an IEM, but not especially prominent in the signature, whatever treble that is present is smooth and detailed, without much in the way of fatiguing peaks. While this means the IEM isn't especially airy, the large stage that it presents prevents it from feeling closed-in.
Soundstage:
As mentioned above, the ASG-1Plus has a rather large stage for an IEM, with great ability to present spatial cues within the music. It is more wide than deep, as per usual with headphones/IEMs, but not overly so, separation and imaging is also good, but the lack of absolute black background prevents this aspect from being excellent.
Comparisons:
Below are comparisons to various IEMs that I have extensive experience with, either through ownership or demos, (* indicates demos)
Sony MDR-EX1000
A legendary Dynamic IEM that is still seen a benchmark to this day. Immediately, the most striking difference is that the Sony's have a much more energetic presentation and thinner notes, courtesy of significant treble emphasis, which includes prominent lower treble peaks that will put off a LOT of people. Needless to say, the Sonys are much more fatiguing, but in exchange, get stunning clarity and resolution in return, not matched by the Aurisonics. Bass is relatively shelved down on the Sonys and doesn't extend as low as the ASG-1Plus, but still provide texture and articulation that matches, if not slightly exceeds the Aurisonics in quality due to its better speed. (16mm dynamic driver doing wonders). Headstage is massively wide (in IEM terms) on the EX1000, but is somewhat flat compared to the more spherical presentation of the Aurisonics. Isolation and wind-noise are big disadvantages to the EX1000 for outdoor use.
MEElectronics P1:
Despite the MSRP difference between the two IEMs ($500 vs $200 for P1), it is the P1 that feels like the higher quality product due to the nice feeling Zinc shells and cabling. The biggest difference sound-wise can be found in the bass, where the P1 somewhat rolls off in the subbass, resulting in a mid-bass oriented hump, the Aurisonics extend all the way, with muscular rumble that the P1 is no match for. There is some upper mid emphasis in the P1 that is also not found with the ASG-1Plus, which makes female vocals more intimate, resolution is similar between the two, besides that, the P1 has thinner notes and can give the perception of being more airier due to some mid-treble peakage not present in the Aurisonic. Isolation is somewhat worse in the P1, as well as comfort, as the mmcx connector doesn't agree with my ear shape.
Campfire Lyra II*:
Lyra II has beautiful ceramic shells that exude quality, with great ergonomics and comfort unfortunately for me, the sound quality does not match the build. Similar to the Aurisonics, there is a clear emphasis in the bass, but it appears to roll off in the subbass, leaving a significant midbass hump that is not to my liking. In addition to this, the dynamic driver in the Lyra II does not appear to be able to convey texture like the larger DDs in the ASG-1Plus and the EX1000, to its credit, it appears to have quicker bass in return, but that is still rather disappointing. Mids on the Lyra II are lush, with an upper mid dip that is similar in presentation to the ASG-1Plus, including the lack of black background that hinders ultimate separation and imaging, even though resolution appears to be better, treble is noticeably more peaky on the Lyra II. Overall, given the price difference between the Lyra II ($699) and the Aurisonics (~200 used), I can't recommend getting it, as the SQ improvements are low for the extra expenditure.
Fender FXA7*:
A comparison between the past of Aurisonics hybrids and the present Fender products might be illuminating. Compared to the ASG-1Plus, the FXA7 appears more v-shaped, with a clearly more bassy tuning, which makes it seem somewhat bloated in comparison, there is also a more severe upper mid suckout on the FXA7, bass texture is similar between the two but the FXA7 appears to be slower. Overall, I am rather disappointed, as it appears to be a step backwards from the old Aurisonics lineup.
Summary
The ASG-1Plus has proven itself to be a great, all-rounded IEM that has earned itself a rightful place in my collection, with a great combination of ergonomics, sound signature and technicalities that compel me to reach for it every time I head out of the house, while the accessories could use some work, the sound more than makes up for it, at the current used price these go for, they are a great value for money and well worth it for those looking for a laid-back, but still engaging signature.

rhythmically inspiring...of course developed for live musicians..that would be useful.
