This adds wireless convenience to IEMs. Paired it with KZ Castor Pro.
ANC : 3/5
it is an added plus but people using IEM do not usually care about ANC. The passive NC depends on the IEM itself.
Sound quality: 4.5/5
With LDAC support, works pretty good with supported devices. I even tried it with Iphone, works really good. Most normal people wont feel any difference over wired. Audiphiles may feel subtle loss of details. But thats what you compromise for convenience. Gain may seem a bit low compared to a DAC+IEM setup but 70-80% volume is sufficiently loud. The audio tone is neutral and balanced
Comfort: 4.5/5 As comfortable as the IEM itself. Gives a Open Wireless earphone feel in terms of comfort. I have wore it over 8-9 hours intermittently playing songs - didnt feel any bulk.
Case: 1/5 Extremely bulky. Forget about keeping in the pockets when you decide to buy this. But treat it like a IEM case. The feel is plasticky and not premium. The adapter themselves feel premium but not the case.
Battery: 4/5 Decent battery backup.Adapters themselves give around 5-6 hours playback at 70-80% volume.
Overall a worth purchase if you are looking for tws convenience with your IEM.
Really appreciatethe quality of this product as it is really a premium quality product with a touch of nice red led ring light. I have paired this DAC with Moondrop chuu 2 IEM. The sound quality is phenomenal. Worth buying and in my opinion its a value for money.
Hi Team, great product , impeccable service, at reasonable cost. Thanks Audio Store.
Just visited an audio store and finally picked up the Moondrop Golden Ages 2, and honestly, the experience was great from start to finish.
The staff were knowledgeable and actually understood what I was looking for instead of just pushing random products. They let me try out different audio gear properly without rushing, which made a big difference in making the right decision.
The overall vibe of the store was clean, organized, and very audio focused. You can tell they cater to enthusiasts, not just casual buyers. Pricing was fair, and they were transparent about everything.
Ended up going with the Moondrop Golden Ages 2, and I’m really happy with the purchase so far.
Definitely recommend this store if you're into good audio gear and want a proper listening experience before buying.
Even from a non-technical perspective, I highly recommend this device. Using this DAC has significantly enhanced the overall audio quality of my listening experience.
When revisiting familiar tracks, the music sounds remarkably fresh. It reveals subtle nuances and details that were previously lost or suppressed by over-emphasized bass on other devices.
The build is quite practical; it is compact and user-friendly. I am currently using it with a OnePlus 13, and the integration is seamless. Most importantly, it delivers premium, high-fidelity sound at a very accessible price point.
It is the best ine you can get under 3000 rs. Moondrop Space Travel 2 delivers impressive sound for the price, with clear vocals, punchy bass, and surprisingly good detail. The fit is comfortable, battery life is decent, and the design feels sleek. ANC is usable, though not class-leading. Overall, it is a fantastic budget TWS option for casual and music-focused listeners.
I was looking for a clean, punchy and impactful bass iem. Stumbled upon multiple options. Got a chance to discuss with Pritam. He suggested Titan but I was hesistant and wanted to try out for myself all the options.
Arranged for AudioStore studio visit and tried out all the options spending a good amount of time with each option. But in the end, Titan won over all others. With each better source it scales so well. When you give it proper gear and power, it acceeds to another dimension. You will feel a subbass fitted in your ears without muddiness.
It still amazes me everyday what such a small IEM can achieve.
Lastly, I would thank Pritam for taking so much time with me, demoing so many iems, discussing and guiding about many different nuances of audio systems. Never for a moment anything felt rushed. Best experience I had! Will definitely visit soon again.
if you want something clean and neat sounding iem, which doesn't add any artificial colors to the sound and if love musical tuning, you will love this Klean.
Not for bass lovers.
I upgraded to Truthear Hexa from Kiwi ears cadenza and my impressions are as follows:
The Lows: The low-end response is incredibly tight and controlled. The sub-bass has great extension and punch, but it stays incredibly disciplined without bleeding into or muddying up the lower frequencies.
The Mids: The midrange is pristine. The upper-mids are beautifully articulate, giving incredible clarity and presence to the center of the mix without sounding shouty or overbearing.
The Highs: The high frequencies are sweet and extended. There is plenty of detail and air up top, but it manages to remain smooth and entirely free of any harsh, fatiguing sibilance.
Coming from the Cadenza, the Hexa feels like a true upgrade in both resolution and tuning. If you are someone who is chasing a perfectly balanced, neutral-leaning sound signature, I cannot recommend the Hexa enough. It is absolutely worth the price.
The Moondrop Space Travel 2 earbuds make a strong case for themselves right from the moment you unbox them. The white-orange colorway is a refreshing departure from the sea of matte-black and all-white earbuds flooding the market — it feels deliberate, bold, and genuinely premium without being loud. Build quality reinforces that first impression, with a finish that looks and feels more expensive than its price suggests.
Where the Space Travel 2 truly shines is in audio performance. The sound signature is detailed and well-balanced, offering clarity that audiophile-leaning brands like Moondrop are known for delivering. Whether you’re listening to tracks with layered instrumentation or taking calls, the audio holds up consistently without fatigue over long sessions.
The headline tech upgrade here is Bluetooth 6, and it delivers. Connectivity is noticeably seamless — pairing is fast, signal dropout is virtually non-existent, and the lower latency makes a real difference when watching videos or gaming. It’s one of those features that you don’t fully appreciate until you’ve used it and then go back to older Bluetooth standards.
Overall, the Moondrop Space Travel 2 hits a sweet spot between aesthetics, audio quality, and modern connectivity. If you want earbuds that stand out visually while delivering a refined listening experience, these deserve serious consideration.
First things first.... The owner Pritam is such a cool guy to do business with. Always available and friendly. He explains things in a way that people other than audiophiles can know how it feels to be an audiophile. Wish i could have met him in person to buy this fabulous product. Now coming to the Volür, This is an absolutely outrageous piece of an IEM. Each and every instruments feel different than i have heard before. I am having hifiman arya headphone also. I use chord mojo 2 dac and i also have cayin ru7. This beats the planar headphone by quite a margin. I also have a premium music system - KEF LS50 meta speakers paired with Chord Qutest DAC and Arcam A15+ amp. Everything is connected with chord reference cables. For those who doesnt know the above setup costs more than 6 lakhs... And the Volür with chord mojo 2 beats them easily. The soundstage is grand. But not too grand as the Sony IER-Z1R. The imaging and listening is experience is so enjoyable and fun packed and its not too critical as the 64 audio U12t. And it fits perfectly too, which most hybrid iems like Thieaudio Monarch can't do... To put these all together, these IEMs aren't the most critical/analytical. These are the ones that gives you EARGASM....
I have the orange version and find it better looking than my friend's black green version. Its a well tuned and balanced sounding tws. Great midrange and bass albeit a bit less clarity. Fit is a bit on the bigger side. App is good and functional but not that smooth like nothingX or boat app. I utilized the bass+ mode for most of my listening. Volume reaches very high without any distortion and also handles EQ well. I have to say the drivers are of good quality. At this price it is a killer tws especially for sq. Fit, comfort & ANC for the price are good but can be better.
First of all, the service of Audio Store is always great.
Aishwarya helped me with the order and shipped the product the same day.
I received my IEMs the next day, and the product is incredible.
I had Kefine Klean, which I also bought from Audio Store, and Tangzu Wan'er SG 2 - Red Lion Edition. But the Simgot EW300 is my favorite so far.
The product is really good in terms of sound quality, default tunings are little low on bass but fatigue free mids and highs, very smooth vocals though user can tune as per the sound signature the need, just install the official app and enjoy.
Build quality of the shell is very nice with small shape than some regular size IEM, and very lightweight making it comfortable for long seasons. Wire looks good but feels not much durable.
Overall this product is pretty good suitable for all type of users.
Finally got the Kefine clean 🎧 DLC driver ka bass aur metal shell ki premium feel... iss budget mein sach mein king hai. Sound signature kaafi musical aur fun hai. Pure value for money
