In this case I believe the Y will act as the coupling chamber, making it essentially the same as the more conventional isobaric setup like you show from the blessing.
Idk though, in a typical isobaric speaker the rear of the drivers are coupled to the same volume (box), here it’s the front. Not sure how reliably these terms can actually be applied here beyond marketing-speak.
Yeah im not fully sure, but it is different from how it usually is and not sure if this method would work the same to be called “isobaric”. But then again, that term is thrown around a LOT.
Not Isobarik two concentric drivers
I’m so hyped for Aful x Terrence Howard Magic 1 x 1 = 2
Bro 
Good one
oh yeah that’s it, it was something I haven’t seen either so I was looking forward to it. I’m down to grab it at some point
It’s also not that 
AFUL Performer 5+2: The New Benchmark in Its Class
Pros: - Very good unboxing experience and accessories
Cons: - Non modular cable
Specs And Driver Configuration
Before starting the review, I want to thank Hifigo for arranging the review tour of this iem in my country. Purchase link - https://hifigo.com/products/aful-performer-7?variant=45949842915567
Unboxing Experience and Accessories Package
The unboxing experience is excellent. You have to side the outer sleeve (which has no waifu) to get to the inner box.
When you open the magnetic flaps of the inner box, the IEMs are elegantly displayed in front of you, with a hockey puck-style case on the opposite side. Below them, you’ll find a selection of eartips neatly arranged for easy access.
The accessories provided are very good. Things provided in the box are 1. hockey puck style case 2. non modular cable 3. three sizes of three different types of tips. The cable provided looks and feels very good. It feels very supple and robust at the same time. It behaves very well as well. One drawback is that it is non modular, many iems in the same price category provide modular termination system.
Eartips provided are very high quality as well, they provide excellent seal and comfort.
The included case is well-built, but its size poses a challenge. It’s cumbersome to fit the IEMs in or take them out with each use. A slightly larger case would have greatly improved usability.
Design, Fit, and Comfort
Aful’s iem design and looks have always been their strong suit. This time is no different. The faceplate design of this IEM is visually striking, featuring a textured, gemstone-like pattern in vibrant shades of blue and green. The triangular geometric lines create a dynamic, fractured look, resembling stained glass or crystal shards, giving the IEMs a sophisticated, high-end appearance. The design strikes a perfect balance between elegance and bling.
The build of this iem is equally as good as it looks. The full resin build feels very sturdy and robust. No, complaints about build quality.
The fit and comfort of this IEM are outstanding, thanks to its compact and ergonomically contoured shell. The small shell size allows it to sit securely in the ear, offering a stable, snug fit that’s comfortable even during extended listening sessions. This shows they put alot of effort into engineering their iems. Additionally, the nozzle diameter is 5.8mm which also aids in excellent fit and comfort.
Sources Used
For my sound testing, I used the Chord Mojo 2, and I found that it drove the IEM effortlessly. I didn’t need to push the Mojo 2 hard to achieve optimal volume levels, indicating that the IEM is easy to power
Frequency Response
I used the stock tips for sound evaluation. Performer 5+2 has a slight U-shaped sound signature.
Bass
Let me say this upfront: this IEM delivers some of the best bass quality in its class, if not the very best. The bass profile is sub bass over mid bass. The bass glides smoothly from sub bass to mid bass. The bass region overall comes across as very dynamic and punchy.
The sub-bass hits deep and low. The sub-bass rumble and texture is also excellent for the price. The sub-bass has sense of depth to it, it’s like it envelops around you. It easily plays the triple drop in the track Kill Jill by Big Boi. The mid-bass thumps and slam is also good. The bass attack is well-defined with just the right amount of decay, leaving nothing to be desired. The tuning strikes a balance that complements nearly all genres, delivering versatility and quality across the board.
Mids
The mids on the Performer 5+2 are expertly tuned, offering a well-textured midrange with impressive detail retrieval. The transition from mid-bass to lower mids is smooth, giving the lower mids a natural heft and body. The upper mids feature an early rise with a flatter pinna gain, which effectively prevents any shoutiness or fatigue. This tuning approach keeps vocals powerful, giving them a subtle boost in the mix without overwhelming other elements.
Overall, the midrange is balanced and cohesive, with a slight boost in the presence region that adds bite to instruments and vocals, avoiding a too-safe or dull sound. Both male and female vocals shine on this IEM, though male vocals, in particular, have a touch more richness. Instruments also come through with a natural timbre, enhancing the realism of the listening experience
Treble
The treble on this IEM is impressive, offering a smooth yet well-extended response. It has an incisive quality, likely due to the micro planar drivers, delivering remarkable clarity and detail. A boost in the mid-treble region adds energy, giving cymbals and hi-hats a slight emphasis. Personally, I feel that the mid-treble could be toned down a bit for a more balanced presentation. The air region is well extended, making the sound feel airy and open. Overall, the treble is incredibly revealing and picks up every little detail in the tracks
Detail retrieval and Technical Performance
Aful performer 5+2 is one the best detail retrieval in its class. It extracts each and every macro and macro nuances from the track. The technical performance is also excellent for the price, especially the staging. Staging is one of the strong suits of this iem. Stage feels very holographic and wide with excellent front and back depth pickup. The instrument separation and laying is also very good. The same goes for imaging as well. You can easily pinpoint all the instruments in the track. The Performer 5+2 also handles busier passages of a track with ease
Aful Performer 5+2 vs Ziigaat Estrella vs Dunu Davinci
So, now let’s start with the comparison. I have chosen dunu davinci and ziigaat estrella. In terms of accessories package performer 5+2 and davinci are almost neck and neck estrella is in last place. But, if have to choose one I will pick davinci. Davinci’s carry case is much better. Performer 5+2’s case is not that good, it is small, and putting iems in after use is very hard. In terms of tips both performer and davinci provide a lot of tips to choose from and ziigaat lags behind in this aspect as well. In terms of cables again estrella is last and performer and davinci are tied both of their cables are robust and sturdy feeling.
In terms of looks and aesthetics, davinci is very royal feeling with its stabilized wood faceplate, estrella is very eye-catching with glitter and speckles in its shell and face plate, and performer 5+2 is also very good looking with a very interesting face plate design. I personally like all of them and choosing between them is hard, but if I had to pick one I would pick estrella as it has more depth to its looks. In terms of build quality all of them feel well built and robust, no issues here. But, estrella has a driver flex issue, you can hear the DDs crinkle when you put the iem into the ear. Davinci and performer 5+2 have no such issues.
If I talk about fit and comfort aful performer 5+2 is the most comfortable among the three, it has the best shell shape and size. Second place goes to estrella and third place to davinci due to its not that great shell shape and thick nozzle.
Now, to the main part. Sound. Performer 5+2 has a U-shaped sound signature, DaVinci has a bassier rendition of new meta tuning and estrella has a v-shaped tuning.
Let’s start with bass. Before I say anything all three have very good bass performance and have very minor differences here and there. In terms of sub-bass rumble and texture, I have to say both performer and estrella tie and davinci is in second place. Both performer 5+2 and estrella hit deep sub-bass notes effortlessly, It’s just that estrella has more sub-bass amount than performer 5+2. In terms of mid bass, davinci takes the win here. davinci ‘s mid-bass feels satisfying and meaty with a very good thump and slam to it. With a very close margin performer 5+2 is in second place the initial attack of mid-bass is more defined in the performer but still, I find davinci’s mid bass to be more satisfying sounding. The third place goes to estrella here.
Now, let’s talk about midrange. If you want the most natural sounding mid range with both excellent male and female vocals davinci is the way to go. Performer 5+2 also has very good lower mids with flatter upper mids which overall sound very good and produces both male and female vocals that well. But, due to the flatter upper mids vocals do not feel as powerful as they can be, so if you want a slightly relaxed uppermids then aful performer 5+2 is the iem for you and when I talk about estrella I fell estrella’s mid range to be slighly recessed so male vocals do not feel that powerful when compared to davinci and performer 5+2 but upper mids are slightly boosted so female vocals feel open, powerful and extended.
In terms of treble smoothness performer 5+2 and davinci have the smoothest treble with estrella to be very close second. In terms of treble tuning, davinci has a relaxed tuning that does not attract your attention towards it, the treble is there to complement the whole sound signature. Performer 5+2’s treble tuning is more detailed and focused. To make it sound more detailed they boosted the 6-8k region, but due to this instruments in this region sound more forward. The estrella’s treble is also detail focused, but there is less elevation in the 6k - 8k region. In terms of treble extension, davinci is in last place. Performer 5+2 and estrella have excellent extension and sound super airy and open.
Now, to the detail retrieval and technical performance. Before starting this segment let me say upfront detail retrieval and technical performance are not Davinci’s strong suit when compared to estrella and performer 5+2. In terms of macro and micro detail pickup it was a very tough call but I would say aful performer 5+2 edges ahead of estrella slightly. In terms of stage width and depth, the clear winner is the performer the stage feels very wide with excellent front and back depth presentation. Performer 5+2 is also better in instrument separation and layering is better on performer 5+2 as well. In terms of imaging, I would estrella is slightly better here.
Conclusion
This IEM redefines what performance in its class can be. If your budget is around $300, I’d say stop searching and just get the Performer 5+2—you won’t regret it. And if your budget is closer to $200, consider saving up a bit more, because the quality here is worth it. I thoroughly enjoyed my time with the Performer 5+2, and it’s hard to find another IEM that brings this level of detail, balance, and enjoyment in this price range. This gets a huge thumbs-up from my end.
I don’t see anyone mention BA’s used. Guess they’re ““custom””?
Not a single word about their BAs.
Very likely to be something like off-the-shelf E/LS-Audio or Bellsing drivers and not even custom ones at that.

My Brief Review of the Aful Performer 5+2 Versus the Performer 5
Thank you for taking your time to read my brief review of the Performer 5+2. I will refer to the Performer 5+2 as the P7, and I will refer to the original Performer 5 as the P5.
A little about myself…
I was born deaf in one ear. My listening experience is the same if you convert the left and right stereo channels to mono and listen to music using only one of your ears. I am unable to talk about soundstage or imaging or the perceived positions of the instruments and musicians. I can talk about the overall tuning, impact and slam, and the fidelity of details. I am 60 years old. Anything above 8 kHz quickly becomes fainter and I can’t hear anything above 12 kHz.
My P7 purchase…
I received the P7 last Friday afternoon. I purchased the P7 on October 31 from HiFiGo. This was the day that it was announced by a redditer here that the P7 was available for purchase and that the price is $240. I received the P7 in only eight days. Thank you HiFiGo for the fast and well tracked shipping!
P7 fit and comfort…
The P7 shells appear to be 2 or 3 mm thicker than the P5 shells. Aside from the thickness, the rest of the shells appear to be the same in terms of size and shape. The nozzle dimensions are identical on both IEMs. The angle of the nozzles appears to be the same as well. The P5 is one of my most comfortably fitting IEMs. The P7 fits just as comfortably was well.
The tuning…
The P7 and the P5 have very similar overall tuning. The overall tuning is very close to my preferred HBB tuning. I agree with a reviewer who commented that tuning is roughly 80% in terms of whether or not a person likes any IEM. I really like the tuning of the P5 and the P7. Both of these IEMs easily pass my initial listening tests for the overall tuning.
The eartips which I used for my evaluation…
I initially used the stock eartips that were installed on the P7. These are small size dark grey eartips with blue inner bores. The bass with the stock eartips was slightly weak in intensity. I did some eartip rolling.
I used Azla SednaEarfitLight eartips on both the P5 and the P7 since even though these are wide bore eartips, they actually improved the P7’s bass in comparison to the stock eartips. Although the stock eartips are rather nice, the Azla eartips are nicer for me since I wanted a bit more bass. The slick thing about the stock eartips is that things get noticeably shifted to a more technical side if this is your thing.
The bass…
The P7 has a noticeably more dynamic bass when compared to the P5. I really like the P5’s natural sounding bass. I like the P7’s bass even more than the P5’s bass. You can read the blah blah blah for the P7’s bass tube technology elsewhere. This technology appears to work amazingly well.
The midrange and upper midrange…
The P7 midrange and upper midrange are very nice and has somewhat yet noticeably better details in comparison to the P5. The midrange and upper midrange are not recessed at all and instead are the proper amount for my tastes. The upper midrange on the P7 sounds more correct than the slightly wonky upper midrange tuning on the P5. Note that the P5’s slightly wonky upper midrange was easy to correct by using a couple of simple parametric EQ tweaks.
I really enjoyed the additional details which the P7 has in the midrange and in the upper midrange. The P5 was my favorite IEM. The P7 now is my favorite IEM. This is not to say that I am no longer satisfied with listening to the P5 since the opposite is true. Cymbals sound nicer and crisper on the P7. I really enjoyed listening to the cymbals in various music tracks when I was using the P7.
The air region…
I can’t hear the air or upper treble region. So, nothing from me!
A simple conclusion…
I am pleasantly satisfied with my purchase of the p7. Even though I really like my P5, I think that my P7 purchase was worth the price in terms of my perceived improvements for the overall sound signature in addition to the improved bass and the improved overall details.
I hope that you enjoyed reading my review.
I did enjoy your take on the set thanks for sharing
