Let customers speak for us
for me this is a game changer it helped me a lot .
value for money
it supports in all devices including macbook and ios devices .i am really satified with purchase . thank you
The Audiocular Beam Portable DAC is definitely worth it. The metal build along with the braided cable feels reassuring and sturdy, and the DAC never felt considerably warm even during longer listening sessions. It also maintains a somewhat neutral sound signature as far as I can tell, and noticeably increases the perceived volume of my KZ Castor Pros. Furthermore, I personally haven't heard any hissing noises on my IEMs, if that is something you're worried about. Finally, the red LED ring light is a cool touch, if a bit gimmicky and distracting during late-night listening sessions, but the bonus Audiocular carrying pouch along with the Type-A converter included in the package is what makes this a great deal. If you're looking for a DAC around ₹1,000, you should certainly consider the Audiocular Beam.
Such a good product is it and the quality of is top notch.
Really happy with the GK Kunten. The build quality feels premium for the price - sturdy metal-look faceplates and a nice detachable braided cable that doesn't tangle easily. Fit is comfortable even for longer listening sessions thanks to the ergonomic shell shape.
Sound-wise, the dynamic driver delivers a full, balanced signature — punchy bass without being overdone, clear mids, and decent treble extension without harshness. The inline mic is a nice bonus for calls.
For the price after the discount, this is excellent value. Packaging was neat and delivery was quick. Would recommend to anyone looking for 'id entry-level IEM upgrade
Cristal clear sound quality.
"Unbeatable planar clarity, smooth treble, and deeply immersive soundstage at this price point!"
I recently purchased the Letshuoer S12 Ultra from The Audio Store, and pairing it with my Samsung S24 Ultra, FIIO BTR17 (via 4.4mm Balanced), and Apple Music Hi-Res Lossless has been nothing short of extraordinary. It delivers a truly world-class listening experience!
Key Highlights:
Planar Technicalities & Imaging: The 14.8mm Planar driver offers lightning-fast transients, laser-sharp instrument separation, and a surprisingly wide, holographic soundstage.
Smooth & Energetic Tuning: Compared to earlier S12 iterations, the Ultra brings a much smoother upper-mid/treble presentation with zero sibilance, while retaining authoritative, deep sub-bass rumble.
Synergy with BTR17: The dual ES9069Q DAC and clean THX amplification from the FIIO BTR17 give the S12 Ultra all the juice it needs to shine.
Build & Accessories: Excellent CNC aluminum shells, ultra-comfortable ergonomics, and a modular 3.5mm/4.4mm silver-plated cable right out of the box.
Verdict:
If you want an endgame-level portable audio setup without breaking the bank, look no further. Kudos to The Audio Store for the lightning-fast delivery and top-notch packaging! 🎧 absolute recommended!
The DAC works like a charm. Works with various devices. Recommended even if it does not come with PEQ. Try Equalizers of your choice to tune the sound as per your taste. I have paired it Duonic (improved bass version)
Just received my order and these little thing is fabulous. Like it just increased my iems potential. Solid quality and looks premium. Easy to carry comes with a fabulous quality case which you can use to store your iems too. Moreover there was really a difference without it and with it in sound and overall. So go for it without any hesitation ✌️
The audio quality is amazing. The noise barely escapes to outside. Overall a great purchase worth the price
I was impressed by fast and well managed delivery 📦 . Coming to moondrop space travel 2 ultra..one word awesome..I was searching for tws loud enough and quality sound and I am fully amazed by sound.
Very best audio quality each and every vocal was crisp and clear in future I will buy more Iem from audio store❤️
After using the Roseselsa Aurora, I can confidently say it's one of the best budget IEMs I've tried. The tuning is fun, vocals are detailed, the bass has good impact, and instrument separation is impressive. It's comfortable, well-built, and makes every song enjoyable. Definitely worth buying if you're looking for a quality IEM. 🎧⭐⭐⭐⭐⭐
Nice dac
I've purchased this kz edx pro 2 with mic and type c I've received in just 2 days and the product is absolute perfect and build quality and audio experience is so good I've loved it and the look also is so good, the quality of mic is good though compare to other mics audio is perfect and smooth for me.
I opened it fastly then at the end i saw take a video while opening sorry audio store. But tbh the wire quality is so good and delivery also came before expected date. If someone reading this comment the 1 reason to buy from audio store is they keep affrodable prices when compared to headphonezone and concept kart and offcourse amazon and the quality is also on top notch
