Binary Dynaquattro 4DD IEM

Review after using it for a few weeks.
The sound quality is really impressive. It is not the absolute best, but one of the best in this budget segment.

The soundstage is wider and instrument separation is really good. I like its natural, linear bass (I am not a basshead). It has smooth, soft, comfortable, and discreet treble (which might not be good for trebleheads). With .flac and LDAC, there is a significant difference. It is good for both male and female voice types.

These might not be the best-sounding, most technical TWS in that budget, but they are good for my use cases.

ANC is good, though it might be improved. Mic quality is good enough, but it sometimes feels a little muffled.

Personally, the diagonal earpieces and oval rubber ear tips fit perfectly. They are comfortable for a long time. Battery life is good for me but not comparable with others; It would be good if there were a feature in the app to see the battery percentage of the case.

Custom and online DSP features are good. However, LDAC can't be used simultaneously with custom DSP and multipoint connections; this should be changed in the next firmware update. Also, sometimes the app feels glitchy and slow.

There is no IP rating mentioned, and the open-lid design is negative.
I might be forgetting something.

While this isn't as much of a "value for money" pick as the Space Travel 2, it is worth it for me because of the sound quality.
My first time buying experience with TheAudioStore is very good

The protective case is made of good quality material and protects the TWS perfectly. The fit is good, but sometimes when taking the buds out, the charging case shifts slightly upward. I put a small piece of paper inside, and now it is perfect.
The texture and colour of leather is good, but it looked washed out because of my phone's camera.

I don't know if it is great value for money, but it provides good protection.

👍

The GK KUNTEN is a highly recommended, low-cost IEM, considered by many to be a "new king" of the ultra-budget audio scene. It is highly regarded for delivering quality sound, good build, and a comfortable listening experience for a very small investment

Upgraded from EDX Pro

i sent these messages to my friend in real time when i was trying out the kefine klean sv in real time

I am very sceptical , But It is Awesome Product man.

It really increase quality of sound and The best part is I can use it My pc as well 😁.

Design is very beautiful and Build quality is also awesome 👍.

Just Go for It.

The product was genuine ✨️ thanks audiostore. The iems are for basshead lovers, it got good amount of bass and if we adjust the EQ of our phone or music player then it can give us good balance sound. It requires power so it needs amp/dac device for better output. I like the product very much.

Provided the original product with no defects also for cheaper price as compared to Amazon or any other store and also delivers with in 5-6 days. Great experience.

As much i have used it for now it really works well you will feels the audio enhancement and increased quality. Worth the money.

These are my fourth pair of IEMs, and honestly, I can’t find a single fault with them. The sound signature is beautifully smooth, well‑tuned, and perfectly balanced. Vocals come through with striking clarity, making every track feel alive. Totally worth it — they deliver an experience that goes beyond expectations.

I’m really impressed with the Hiby R1 — such a compact device, yet it delivers powerhouse performance. The raw specs on a spreadsheet don’t capture the real experience. Once you pair it with Type‑C IEMs and play FLAC files, the sound quality speaks for itself: clean, detailed, and surprisingly dynamic for something so portable. It’s proof that great audio isn’t just about numbers, but about how the gear actually performs in your hands (and ears).

It was neatly packed and unexpected case has been delivered along with the DAC. Had a nice experience too with the product. Loved it!

I've previously owned some budget iems like kz zex, tangzu wan'er and chu 2 but Ohh boy the sounds on STA HI-END is so soothing and melodious and it handles eq like a champ so no complaints from there too. Absolutely go for it you won't regret

Powerful, clear and you can hear the complete trace of audio.

I have been using the Tanchjim Bunny DSP for a while, and for the price, it’s honestly a very good set of earphones. The build quality is very simple but good, and the light weight makes it very comfortable for long usage.

The sound quality is very balanced for the price. The bass is good and controlled rather than overemphasized, and the mids are good so that the vocals are very natural, and the trebles are good and detailed but not harsh. This makes them very good for all types of music.

The Tanchjim Bunny DSP is a very good earphone for the price, and I would recommend it for people who are looking for a very simple plug-and-play earphone with good sound quality.
