Let customers speak for us
It's truly velvetty- If I can say so. Good for IEM's with large nozzles .
Delivery on time, Good product, Happy to purchase overall
I own a Simgot ET142. Wanted a pure planar and my choices were the Letshouer S12Pro , 7Hz Timeless and the Sivga Nightingale.
The Sivga isn’t available in India.
The Letshouer reviews had me confused between the S12 and its upgrade the S15.
The 7Hz was a notch lower compared to the Letshouers.
Finally I decided to pitch in for the S15 considering that the audio store has a sale on it and the pricewas better than that offered on HPZ and Conceptkart and Desertkart.
I am happy with my gamble.
Bass , Mids and treble are all aligned perfectly to my preferences. A mild V shaped profile. Rich warm bass and smooth trebles without harshness.
Thank you Audio store.
Pre-ordered the Top pro and received it in a week.
IEM is Excellent
The bass is there, doesn't overwhelm but when it hits you can feel in the chest
Treble is the smoothest I've heard
Vocals are clean
Seperation is top notch
Worth.
The sound is fucking great for the price….the voices rock..bass is not over justified….balanced and provides according to track,one downside because of which I’m rating 4..is the fit…hurts my ears even after 1 hr….might adjust to different ear shapes of diff ppl..overall satisfied for the money….if u skip bass….it kills the market opponents like realme air 7 pro and one plus buds 4 also one more thing ..the case feels a bit cheap…and might get scratched ez..and since it’s quite uncommon set of buds…u don’t get any protective cases as such
TANCHJIM Bunny has an excellent sound signature to start with - clean, energetic and fun it works beautifully with jazz, R&B, hip-hop and even bollywood music. But it's possibilities just start there. Once you connect these IEMs to your phone and download the Tanchjim app, you would discover a ton of sound profiles pre-saved. There are 4-5 official sound signatures, but even more are the access to thousands of fan created sound signatures. You can tune it to any of the hundreds of IEMs available - everyday a new IEM, if you like. The play opportunities are endless. The build could be better - looks kind of cheap compared to the solid metal body of the Chu 2, but no complaints as far as sound goes.
Exceptional delivery by theaudiostore.
The packaging was really well done.
The Bunnys blew my mind when I first used it, it sounds so much clear than my Airpods Pros!
Anyone getting their first IEMs go for this!
The build quality is sturdy & good. The new design is nice. Work well without any hissing noise or heating. Using it on my CMF Phone 1 🙌✨
Adequate purchase, best sound you will hear.
Probably double volume than TWS.
Looks seriously different than other headphones I have used till now, you look different than rest of the crowd(in the gym especially), that makes you feel special 😊☺️
Must go for it Bluetooth & DAC AMP
- Audiocular SPARK DAC is one of the best looking dongle DAC I can find also the audio quality it throws it's just supirior to any normal phone or pc DAC.
-Well there is lot of DAC with same configuration but on higher price this one feels premium and it's just under 1000 bucks so I don't think so you need anything else as a beginner or anywhere for regular use it's best of best.
- I was really confused between salnotes zero 2 and moondrops chu 2. After lot of thinking and chatgpt decided to go for Chu 2 well my initial experience was not good because I was using realme airbuds 5 pro which is a great wireless earphone dual drivers but mostly bass heavy so chu 2 bass felt lacking at start but it's just initial expression once I got comfortable with it is blown my mind cause it's really well balanced you can hear good amount of sound seperation bass is good and don't leak into the other instrument details or vocals.
- I purchased it with audiocular spark DAC
And honestly it's deadly combo it improves so much sound quality and bass and on top of that the fit of chu 2 and cable is really good and with this DAC it feels aesthetically pleasing as well.
Awesome Product...
Awesome headset
