MOONDROP Nice Buds Wired Earbuds
15.4mm Dynamic Driver Flat-Head Earphones with Enhanced Bass Airflow
Rediscover the charm of classic flat-headed earbuds—reimagined with modern acoustic engineering. The MOONDROP Nice Buds mark a return to the brand’s roots, blending timeless earbud design with advanced driver tuning, structural innovation, and refined ergonomics.
Originally, MOONDROP’s journey began a decade ago with flat-head earbuds that gained wide appreciation for their natural tuning and musical character. With Nice Buds, that legacy continues—now elevated with precise airflow control, improved bass response, and enhanced wearing comfort for today’s listeners.
Powerful 15.4mm Dynamic Driver with Natural Timbre
At the heart of the MOONDROP Nice Buds lies a large 15.4mm neodymium dynamic driver, specially optimized for open-fit earbuds. This oversized diaphragm improves resonance coupling, allowing the earbuds to deliver a smooth, warm, and realistic sound signature with excellent tonal balance.
Vocals sound lifelike, instruments retain their natural texture, and the overall presentation remains fatigue-free—ideal for long listening sessions.
Dual Rear-Cavity Damping with Bass Enhancement Airflow Tube
Flat-head earbuds often struggle with bass presence—but Nice Buds solve this elegantly.
A dual rear-cavity damping system, combined with an integrated bass-enhancement airflow tube, precisely regulates low-frequency movement. Four high-damping vents manage pressure across two frequency bands, resulting in:
-
Deeper and cleaner bass
-
Controlled mid-bass punch
-
Clear mids without bloom or muddiness
This design brings rare low-end authority to open earbuds—without compromising clarity.
Precision Multi-Pore Front Acoustic Structure
The redesigned front cover features multi-pore acoustic ventilation and internal waveguide channels. This structure ensures stable airflow, accurate wave transmission, and improved sound dispersion.
The result is enhanced transparency, better detail retrieval, and cleaner treble extension, delivering a more coherent and immersive listening experience.
Secure Sponge Ear-Tips Positioning Design
To solve a long-standing issue with flat earbuds, Nice Buds incorporate a hub-style sponge positioning limit. This prevents sponge tips from shifting or falling off during use, ensuring:
-
Consistent acoustic performance
-
Improved comfort
-
Better long-term durability
A small detail that makes a big difference in everyday listening.
Ergonomic Asymmetric Shell for Better Fit & Bass
Unlike traditional symmetrical earbuds, Nice Buds use an ergonomic asymmetric shell design shaped to follow the natural ear contour. This improves contact near the tragus and canal entrance, offering:
-
More stable fit
-
Reduced pressure and fatigue
-
Improved low-frequency response due to better sealing
Comfort meets acoustics in perfect balance.
Modernist Geometric Aesthetic
Inspired by the classic MX500 silhouette, the Nice Buds adopt a modernist geometric visual language. Clean lines, refined proportions, and transparent design options reflect MOONDROP’s signature blend of engineering precision and minimal elegance.
Available in transparent and black-transparent finishes, they look as refined as they sound.

Good case to protect your iem
Such a great 👍 product
The product functioned flawlessly for 11 months and ranked as the top option in its category, yet it abruptly stopped working and is no longer detected anywhere.
Good One. But it doesn't have app support as this is the old model. it doesn't have audiocular app support. it is same as 699 rs DAC. Not have any huge difference,
Great great DAC for majority of the audience. Does a great job in audio quality plus if you use a dedicated app that directly interacts with DAC that is just incredible!!
It just works amazing with all of my audio products
Really good DAC and perfect for apple devices as it does not reduce the volume like few other DACs..and very good delivery experience from TAS..👍🏻
Good product and excellent packing, pouch was also good quality one
Does nice job
Observed noticeable difference iin audio quality after using this dac, heard reviews complaining about static white noise but I haven't experienced any such issues yet
I initially thought this case would be small and feel cheap, but I was surprised after receiving it. The size is actually bigger than expected, which turned out to be a good thing because it easily fits my IEMs along with a DAC and accessories without feeling cramped.
The case is quite rigid and sturdy, giving good protection while carrying it around. The build quality feels much better than what I expected for the price. Overall, really happy with the purchase and it works great for storing both IEMs and DAC together safely.
Hi Team, great product , impeccable service, at reasonable cost. Thanks Audio Store.
Most bast DACK on this prise range an existing case and type -c to USB converter otg buty full luck and wark quality thank you 🌹
Good dac, i had previously one 3.5 to c tye converter it was basic with no chip .this dac really draw out the juice from your phones to shake drivers . Nd if u guys have impedance issue you can use equilizer nd see the magic . This dac works well. Nd yes dac is essential to draw out the required Current/power.
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 😁.

Just Go for It.
As much i have used it for now it really works well you will feels the audio enhancement and increased quality. Worth the money.
I dont know perfect use of it, but helped me to connect with my phone for iem experience
It was neatly packed and unexpected case has been delivered along with the DAC. Had a nice experience too with the product. Loved it!
Powerful, clear and you can hear the complete trace of audio.
Bets budget dac that gives you clear mids and more treble extension... If you are into edm trance symphony orchestra style music... then you will hear better instrument separation...
The cable is soft material so not for on the go will wear and tear... If you are musichead and always hooked then better go with audiocular beam it has cavlar braided cable for good rough n tough life space
Heard a lot of stuff on internet about this dac like hitching or buzzing sound and was bit nervous , but after purchasing I haven't faced any problem with it and I'm fully satisfied with the build and sound quality of the product.

This is the most balanced sounding IEM I've used in this price. I am using the Type C variant, and I haven't experienced any issue regarding the playback whatsoever. It is equipped with the DAC chip CX31993, which is found on the dedicated DACs around the price of 1K. The cable is also a 4-core silver plated copper one, with really nice build quality. These are also really responsive to EQ Settings, tweaking the audio balance using a 10 or 31 band EQ makes the experience even more versatile.
The only cons I have noticed are regarding the in-box ear tips, I didn't find them to be very comfortable, so I had switch them with some other ear tips. Although, the metal built of the IEMs give them a really premium feeling, the glossy surface is extremely prone to scratches and they still get scratched even after using cautiously.
It is good but could be a bit sharp sometimes may be balanced by EQ. But one problem in my type C unit, after 3 days it stop sound out of nowhere, while listening music, or watching movie/yt. Have to plug out plug in to get the audio back.
This is a magical DAC, I don’t believe ki isne mere headphones main jaan daal di ho
Really the quality of aurora ultra is out of the box , literally if you never use an iem and experience first time you feel actual music. Aurora ultra give life best experience.
This is only possible because of the audio that my first experience and the audio store surve there best to just create my best experience thanks a lot for protective, timely delivery and
Again thanks for giving that service and seamless experience to the team

Good and Trusted Place for earphones and headphones who are audiophile. I recently purchased the Moondrop Golden ages 2. The Product is genuine and new.
Thanks. The Audio Store.
This can indeed be an endgame purchase. It ticks all the boxes well and ensures a great fit and amazing audio quality
Amazing single DD iem , the ceramic dome diaphragm is incredibly fast, the transient response is excellent which makes the instruments separation really good, mid bass is punch is excellent, the kick drums have incredibly fast attack, with enough weight and fast decay, the sub bass rumble is not much (good from gaming pov) vocals are quite forward and have good weight, highs can be a bit fatiguing for many but the driver has been tuned that way for gaming, the imaging and soundstage is holograhic, footsteps are other audio cues are very easy to pin point accurately.
Nice product and quality also good😊 sound is awesome only bass is not high else verything was perfect. Happy with the product.
The best IEM Earbuds at this price with Planar Drivers and Bluetooth 6.0 and the cherry on top of having a LDAC truly a Audiophile's dream.
This is my first IEM , I have been watching lots of iem videos and comparison to find a right pair for my purpose ( mainly watching movies of all genre and music ) .
I was about to purchase kz duonic but one of the youtuber suggest earacoustic cipher gaming as an better version of kz duonic.
It have really good bass and also have wide sound stage for my purpose.
I'm absolutely enjoying this one.
So this was my first ever iem. I think I picked the right one Choosing this. The one I got is type c with mic the mic is not that much but the iems are amazing. Has good details and sub bass. And for me I play a ton of games the details I'm getting on this is just crazy.
Good case to protect your iem
Such a great 👍 product
