The Aurisonics Rockets was purchased by me from Hifiheadphones UK in their big clearance of Aurisonics items after it was official the Fender has now acquired Aurisonics. As already mentioned Aurisonics was acquired by Fender not long ago so I won’t spend any time in telling their story here.
I’m a 43 year old music and sound lover that changed my focus from speakers to headphones and IEM’s about five years ago. My preferences are towards full sized open headphones and I believe that also says something about what kind of sound signature I prefer (large soundstage in all directions, balanced and organic sound). My music preferences are pretty much all over the place (only excluding classical music, jazz and really heavy metal). I’m a sucker for value for money on most things in life, Head-Fi related stuff is no exception. It’s been some variations on the Rockets with microphone (only KS if I understand correctly) and also a Massdrop edition with different cable (or at least a different color on the cable). The build of the Rockets are probably the best I’ve ever seen in an IEM featuring crafted titanium housings, quad-weave aramid cable (whatever that means ;)), excellent ergonomics and isolation. The housings are very small, feel very solid and are also very lightweight and I seriously doubt that anything will go wrong with them. The retail package is nice and the metal box is a nice change from the standard paper boxes.
The Rockets are harder than average to drive but still works fine even with my LG G3 phone. I'm not overly crazy about the sticky stock tips so instead I'm using them with some tips from my RHA s500's. I’ve used these back and forward for the last couple of weeks and they’ve played for well over 100 hours. The overall sound signature on Rockets is mid-centric, full, smooth and very non-fatiguing. The bass is very good in quality across the board with a good balance between mid-bass and sub-bass. The treble is also full and smooth and although extension is quite good it does roll off a bit steep in the top and I could personally have wished for a touch more sparkle. In addition to the amazing midrange one other thing that’s obvious pretty soon when you put these in your ears for the first time is the amazing timbre it adds to notes and vocals.
Please note that the comments in the comparison section are not in absolute terms but in comparison between subject A and B.
I find them both very comfortable and although built is great on both the Rockets takes the lead. Those who knows me also know that the Havi B3Pro1 is one of my all-time favorite IEM’s (despite its low price) and I therefore often use them in the comparison section although they’re often much cheaper that the object they’re compared to.
After my experience with the Rockets I caved in and bought the ASG-1PLUS as well as it was said by many that they we’re the ones of the higher tier Aurisonics offerings that was most similar to the Rockets.
Built is excellent on both but with its Kevlar cable and titanium housings I’d still put the Rockets in front.
It has a great build quality (probably the best I’ve ever seen), is extremely comfortable, isolate excellent, is waterproof and has a very easily enjoyable sound signature that’s extremely non-fatiguing. Unfortunately the fact that Fender acquired Aurisonics leaves some questions about the future of the Rockets but I for one sure hope that they’ll still be around in one way or another. I’m a bit of a noob with regard to Aurisonics, having never heard any of their earphones before.
I was provided the Aurisonics Rockets as part of a mini-tour organised by H20Fidelity.  Due to an impending business trip, I not only had a week of critical listening, but also a further 3 weeks of using them during my trip (including air travel), so I’ve had a pretty good chance to get to know them. I am not associated with Aurisonics in any way, I am receiving no form of compensation for this review, and this is my honest opinion of the Aurisonics Rockets. This is a purely subjective review - my gear, my ears, and my experience.  Please take it all with a grain of salt - especially if it does not match your own experience. The Aurisonics Rockets arrived in a very small metal box, about the same size as Cmoy type amp. Opening the tin reveals a black leather carry pouch which holds the Rockets, two “Antiloop” stability devices, two “Tri-tab” stability devices and 4 pairs of SureSeal tips. The tips look to be fairly decent, and come in the normal S,M, L variety, with the last pair being somewhere between M and L, with a slightly different (more conical) shape. The one issue I have with the Antiloops is that I had to search the net to find out how to actually use them – and they didn’t really “assist” routing the cables over ear.  They did lock the position of the rockets fairly solidly – I just found the harder material pretty uncomfortable. There are some graphs out there of the Aurisonics Rockets already – but I really wanted to compare them directly to some of my other headphones (Trinity Delta and DUNU DN-2000J), so I decided to measure them myself.  It takes a little more work – but gives me a better baseline for understanding what I’m hearing. So here are the measurements for the Aurisonics Rockets (after conversion), and below is the graph.
What I’m actually hearing is a clear, and quite forward mid-range, really smooth treble presentation (perhaps a bit rolled off), and a relatively flat low end end. When looking at the build quality and design of the Rockets, the word “bullet-proof” comes to mind, closely followed by the word “tiny”.
The body measures just 15mm from rear to tip of the nozzle, and has a circumference of just 6mm.

The cable IMO is a work of art.  As I mentioned above, it is a quad weave aramid kevlar sheathed cable. Aursonics also advises that the Rockets are waterproof (IP65 rated), and although you wouldn’t want to go swimming with them, they should be good for use in the rain, and also a natural choice for working out (sweat).
As I’ve said many times in my other reviews, I have one ear canal slightly different to the other one (my right is very slightly smaller) - so I tend to find that usually single silicon flanges don't fit overly well.  This time I did try the included SureSeal tips, and the combination of shape and also the material (thermoplastic elastomer) did actually work pretty well. Comfort and fit are both very good over ear, and the cable is very good to work with.  I did have to use the cinch to keep the cable snugged over ear – but, hey, that is what it is there for. Isolation though is really good for a dynamic driver, and I did get to use them several times during some long haul flights.
The Rockets remind me a lot of the Shure SE535 – quite linear and relatively quick bass, a forward (or pronounced) mid-range, and gently rolling off treble.  They are clear but smooth – whilst they have good definition, they are not what I would call overly detailed.
Starting with my usual go-to tracks (“Gaucho” and “Sultans of Swing”), and the immediate impression with both tracks is balanced and very smooth.
The Aurisonics Rockets don’t have a huge width of stage – even with the binaural track “Tundra” – but then again most IEM’s struggle to get out of head.
McKennitt’s “Dante’s Prayer” is next, and the Rockets do well with this track.  Stage size is very intimate – Loreena is only a few feet away, and the piano and cello are both playing next to me, but the tonality is very good. My last test was with Amanda Marshall’s “Let It Rain” and this presentation is very good vocally.
The big question I had after my time with the Rockets casual listening was whether they could do full justice to the bass on my test tracks. Last test was Amy Winehouse’s “You Know I’m No Good” – and again the bass delivery is very consistent.  Very linear, with enough impact to keep things interesting, but by no means bass cannons.
Anyone who follows my reviews will know that around 60-65% of my music is made up of female artists.  So the presentation of female vocals is important to me. Hopefully Fender will treat the legacy of Aurisonics with respect and I’ll get to tell their story in future reviews instead.
At that time I realized that it wasn’t realistic for me to have all the different setups that I wanted and still house a family of four children and a wife so my interest turned first to full sized headphones and later also IEM’s. The ones I’ve got is the “regular” version and it also seems to be the only one available now. As a matter of fact it may be too sturdy since it introduce quite a bit of microphonics when moving around with it. To me it also sets the standard for what the Rockets are all about: versatility and sturdiness. I’ve used them both around the house and when out and about and I haven’t really found any significant weaknesses in the way they’re designed. That being said I’ve got to admit that I love the sound from them when paired with the Cayin C5, excellent synergy. It’s full, lush and liquid and it’s also what you’ll notice first when putting them in your ears.
Then again by adding more energy the non-fatiguing nature of the Rockets might have been compromised so I won’t complain too loudly about it. This means (as an example) that if subject A is found to be brighter than subject B it does not necessarily mean that subject A is bright sounding in absolute terms.
Compared to the Rockets the LTD’s has a quite similar bass presence but sub-bass reaches a bit lower and has more impact. Compared to the Rockets the Havi’s has a bigger soundstage width and an overall thinner sound. Add to this the fact that they sound good with most kind of music and are not particularly picky about the source. It may also feel as a waste of time reviewing them because of this but the fact that they’re still available for purchase and that I like them a lot still pushed me to take the time to do it. However, I had heard a lot of good things about the Aurisonics Rockets, so when my trans-Tasman mate H20 asked me if I’d like to spend some time with his pair, I jumped at the chance.
Literally – which is why our In-ear Headphones™ fit superbly and are built to last through the daily rigours of life. I’d estimate I’ve probably spent around 40-50 hours listening time with the Rockets before I started writing this review. The box has two pretty simple stickers – one on the front showing a picture of the Rockets with some descriptive information, and one on the back with some marketing information, specifications and accessory information. According to the literature, these are made from an ultra-high quality medical grade thermoplastic elastomer, and are made to hold their shape while providing an incredible seal with unmatched comfort for your ears. The Tri-tabs are soft silicone, and are designed so that the tabs on the Tri-tabs lock against the ridges in your ear to prevent them sliding out.   The Antiloops are a harder (but still flexible) plastic which can be used for routing the cables over your ears or behind the head. I used a louder than normal listening level and set tones – so I could measure accurately and be above the noise floor.  All readings were checked twice. There is a faint hint of a mid-bass bump, but no bloat.  The Rockets actually sound pretty natural – except the mids remind me a lot of the Shure series in their quite forward and smooth nature. The Rockets appear to be milled from a single piece of Titanium, and although they are cartridge shaped, it’s the smallest cartridge I’ve come across (when we’re talking IEMs). This is military grade and incredibly strong, and because of this Aurisonics have not included strain relief at the rear of the IEM – simply because it is not needed.

It has a single section above the Y split for each earphone, and a double below the Y-split (side-by-side).  There are some microphonics if worn cable down, but virtually free from cable noise if work over-ear.
I also tried a number of other tips including spiral dots, Ostry tips (great fit and seal) and Complys (T400s actually fit pretty well). Through most of the review I just used the IEMs without the AntiLoops or TriTabs.  The minsicule size means a really nice comfortable fit (after a while they just disappear), and I could see these being very good for any activity – including exercise or sleeping.
They don’t fully isolate engine noise, but with music playing, it is minimised, and I had no issues at all with getting a comfortable signal to outside noise ratio.  What was also strange was that despite the high isolation and no noticeable vent – there just didn’t seem to be any driver flex.
The applause at the end of this track can sometime involve the listener when the earphones manage to convey a connection via soundstaging and imaging (it’s why I use this track so much). Mark Lanegan’s “Bleeding Muddy Waters” is always first up.  Any sign of muddiness or bass bleed is usually exposed very quickly with this track.
My first test is always Agnes Obel’s “Aventine” which tends to expose if the upper mid-range is short or overly forward.
I’ve never been particularly sensitive to microphonics so it’s not a big deal for me but might be for others. These are some of the best mids I’ve ever heard and they carry enough fullness to give male voices enough weight and an overall fantastic sound. I’ve read some comments that call the presentation of the Rockets for two dimensional, in my opinion nothing could be more further from the way I hear them. The sub bass digs deeper and overall bass has a greater presence and drive (especially with electronic music). In total it’s as if Aurisonics really designed the sound of the Rockets to match the looks and features: an easy going sound able to be enjoyed from anything, anywhere. Aurisonics® was founded in 2011 by vocalist, veteran master audio engineer, and audio products designer, Dale Lott. We bring our extensive experience in engineering military spec products into the design of all Aurisonics® products. I wasn’t able to find a port for venting the dynamic driver – perhaps because it’s so small it doesn’t need it?
As I mentioned earlier, I haven’t been able to properly work out the use of the Antiloops – but over-ear and using the cinch works really well. The most consistent, comfortable and best seal was with my Sony Isolation tips though, but the downside was the vacuum issues.
There was however some issues with vacuum seal (it was too good), and any changes in pressure were then magnified.  It is one of the few faults with this design IMO.
The staging is very circumaural and believable, and image placement within that stage is very consistent.
The presentation overall as pretty good – I would have preferred (again) just a little more upper mid-range, and the Rockets did sound a little darker than what I’m used to – but I could get used to this presentation over time. Soundstage width is quite good but depth and layering is really great giving them a great sense of 3D presentation. Bass quantity is still larger on the Rockets while quality is similar but the Havi’s actually has better extension.
Midrange is just amazing and liquid on both but the Rockets are even more lush but also more intimate in its presentation while the 1PLUS adds more air to its presentation. Our In-ear Headphones™ don’t only sound amazing, they are also workhorses that are built to last, with some even meeting and exceeding military specifications for strength and waterproofing. My best experience with the Rockets was actually using Comply tips – which sacrificed a little isolation in return for less seal vacuum issues. Bass compliments without over powering, and the only complaint I would have is that cymbals (while there) are in the background, and quite distant. Although I find the bass sufficient for my preferences I wouldn’t recommend them to bass heads. Clarity and detail retrieval are about average for an IEM at this price point but in combination with the lush and laid back overall signature it’s still very impressive. The Rockets actually has a fuller and lusher midrange, especially upper mids, while the LTD’s more airy sounding. The treble is smooth and full on both but even more so on the Rockets while the 1PLUS has better extension and more easily noticed details in the top. The Havi’s has better treble extension and none of them are prone to sibilance while the Rockets again has a fuller treble. Separation is slightly better on the Havi’s while the Rockets actually offer better layering and depth.
The treble on the Rockets are thicker in the same way as the upper midrange and it also feels more articulated.
