6-Driver Hybrid Configuration
The ZiiGaat x Jays Audio ESTRELLA IEM is a high-performance hybrid in-ear monitor that features a sophisticated combination of two advanced driver technologies. Each earpiece is equipped with six drivers: two custom 10-mm PET diaphragm coaxial dynamic drivers for powerful, impactful bass, and four independent balanced armature (BA) drivers that deliver rich, detailed mids and trebles. These include American Knowles 29689 and European Sonion 2345 full-range BA drivers, along with Sonion E50 series BA super tweeters, ensuring an immersive and high-fidelity audio experience.
Powerful Bass-Centric Tuning
The ESTRELLA is designed to be a powerhouse of sound. With an impressive 15dB sub-bass boost, it produces an extraordinary level of raw, powerful bass, showcasing the full potential of its dual dynamic driver system. The IEM’s crisp treble and lush mids enhance this bass, creating a dynamic and engaging musical experience. The ESTRELLA is ideal for bass enthusiasts and those seeking a unique and mesmerizing sound signature.
3-Way Crossover Tuning for Tonal Balance
Achieving tonal balance is crucial in hybrid IEM design, and the ESTRELLA excels in this area with its 3-way crossover system. This system utilizes three independent sound tubes to deliver acoustic linearity and tonal balance. The focused sub-bass impact is paired with strong kick drum emphasis, while the mids, enriched by two full-range BA drivers, offer natural warmth and fullness. The trebles are crystal clear and refined, thanks to the latest Sonion ultra-treble tweeter.

Behind the Design — A Message from Jay's Audio
“When creating the ESTRELLA, our goal was to craft an IEM that is dynamically rich, exciting, powerful, and beautiful, embodying the essence of the word 'Star' that inspired its name. It was important for us to create an IEM that fully connects with its listener and enhances the joy that music brings. Even though our earlier prototypes were impressive, the ESTRELLA stood out by making me feel truly connected to the music. I couldn’t stop moving to the beat, and it brought a smile to my face every time. Having tested over 300 IEMs, the ESTRELLA remains a breath of fresh air in a crowded market, a spark of excitement that keeps me smiling. I hope it brings the same joy to you, because that’s what it’s all about—the music.” —Jay (from Jay’s Audio)

I am using this for my daily use. This is so good even tunable to an extent. Good quality build and audio
Best in class adapter for various IEM's. I used it with KZ caster, Fiio JD1 and KZ ZEX. All works perfectly. My choice currently is with KZ ZEX. Instead of Touch, button system to control is too good and easily fits in our ear. ANC is not too aggressive, but quite good. Transparency mode is effective. So finally it's a perfect buy for our IEM's. KZ Rockzzz.
Got this over Waner II and Bunny DSP and it was totally worth it. Loving it so far. It supports my s21 FE and Lenovo LOQ Laptop. Let's see how long it lasts.
It’s neutral and clean and slightly warm because of copper.
This cable is perceived as giving a slightly warm-toned character, with clarity and neutrality in the mix.
Superb quality. Very flexible & easy to move around. Good sound quality, it works well in practical use with their DAC/AMP chain.
It Perfectly fit my bunny's. Fixes to ear way better and Definitely heavier than the default dsp cable.
The FiiO BTR5 2021 is a well-regarded portable Bluetooth DAC/AMP known for its strong decoding ability thanks to the dual ES9219C DAC chips. It supports high-resolution audio, including MQA decoding and up to 16x MQA [Discontinued, but not completely] unfolding when paired with compatible sources. The device provides versatile connectivity options such as balanced 2.5mm and single-ended 3.5mm headphone outputs, USB-C DAC functionality, and Bluetooth 5.0 for wireless listening. It features a sleek design with an aluminum and glass build, accented by a small display that shows audio info, though the display can sometimes be unreliable in showing the exact source or codec.
Compared to the original BTR5 from 2020, the 2021 model adds MQA support, a new DAC chip for better performance and noise ratio, and an improved USB audio adapter mode that disables charging during USB DAC use. It comes with a short skin-friendly USB-C cable and a redesigned packaging.
One critical caution for the BTR5 2021 (MQA version) is with the FiiO Control app's equalizer function: using the EQ on the device firmware via this app can brick the device permanently. Users recommend applying EQ only on the phone side with apps like Wavelet instead, to avoid this issue.
In its price range, the BTR5 2021 remains competitive, especially for users prioritizing sound quality, build, and MQA support. However, some users compare it with newer or alternative models such as the FiiO BTR15 (which offers Bluetooth 5.1 and 4.4mm balanced output) or the Qudelix 5K(Gone forever), which has more extensive software EQ features but a less premium build.
Overall, the Fiio BTR5 2021 is a solid choice for audiophiles wanting a portable DAC/AMP with both wireless and wired support, especially if you avoid the Fiio app's device EQ to prevent bricking issues. It has a mature firmware, strong sound performance, and versatile connectivity suitable for IEMs and headphones.
After a lot of deliberation I bought this as my first IEM. Loved it at my first listen. Still my go to IEM. It has a slight u shape that gives a musical tone to the sound. Caters to a lot of genres. It can be driven by 60mW cheap dongle DAC and amps. Absolute value for money.
I was having a huge dilemma switching from a budget IEM to a midrange IEM and I got this masterpiece... KEFINE KLEAN provides Tank like Build ✅ "Sufficient" bass To Power up Any Tracks and Sound stage Was Better than any Other Iems at this price.

I purchased the EarAcoustic STA Hi-End Series IEM from The Audio Store in Pune about two weeks ago, and I’m extremely happy with both the product and the overall experience.
Starting with the store — the atmosphere was excellent and very comfortable for auditioning different IEMs. The owner himself assisted me personally, and I truly appreciate the warm and professional treatment I received. Despite it being after office hours, he patiently stayed back late just to help me choose the perfect IEM according to my sound preferences — something you rarely experience nowadays.
Coming to the EarAcoustic STA Hi-End IEM, after two weeks of regular use, I can confidently say it’s a brilliant performer in its price range. The soundstage is wide and natural, with crisp highs, balanced mids, and a tight, detailed bass response. It handles every genre — from vocals to instrumental and EDM — with ease. Build quality feels premium, and comfort during long listening sessions is gets better as you use them daily. My ear adapted these according to their shape though after 2-3 hours a very little pain felt sometime.
Overall, both the product quality and the buying experience exceeded my expectations. Highly recommend The Audio Store, Pune for any serious audio enthusiast looking for genuine advice and a premium shopping experience.
Recieved before 2days of targeted shipment date.
Quality is awesome.
This is my first IEM, and coming from Sony MDR 7506 and Airpods Pro i feel this sounds more richer and detailed.
It was great purchase and I'm happy from the output of this one. And as much as i love music , i have specific demands to meet like well balanced mids and highs but also good punchy bass. I'm happy with this purchase and i love it.
This was my first purchase from The Audio Store, and I was a bit hesitant at first, but they proved me wrong! The whole process was seamless, and I even received my order earlier than expected. The IEMs are really good and totally worth the money.
If this is your pick than go for it blindly!!!👌🎧
These are a great pick if you love a balanced sound. The best thing about them is the vocals — clear, natural, and full of emotion. You can really feel the singer’s presence without any sharpness or muddiness. Everything just sounds right, especially for long listening sessions.
Audiocular packaging is premium always give a small pouch which can be very handy.Initially Right side was not working in my KZ Harman target Balanced version. Date Recd 7th Oct 2025! every thing is awesome Love Pritam for being Down to earth.I am going crazy at age 51 with this music world man
