Compact portable DAC delivering "awesome sound quality" with 4.4mm balanced output at an affordable price. Customers praised the "little powerhouse" for clarity and premium finish. Works well with tablets and laptops. Main concern: doesn't fit well with phone cases, requiring an adapter. Compatibility varies across devices.
Love the fact that it’s so tiny and one of the most affordable ways to get at a 4.4 balanced output. Delivers the power required but, but, but.. doesn’t play nice with a phone case. Had to get a dongle for the dongle which looks weird. Sits well on my laptop and iPad though.
Pretty good and compact Dac at this price range.
I can use my secondary phone as a DAP now. All thanks to this DAC xD.
I've checked 3.5mm jack port with type-c and USB - sound quality is good
This DAC has comparatively low sound quality compared to moondrop pro when using with Motorola edge 30. But my Nokia tablet won’t work with moondrop pro or Audiocular D07 model DAC. But this DAC works with Nokia tablet and sound quality is higher when compared with using it with edge 30 for the same song. Also when using a specific earphone moondrop pro heats a little but I don’t have this issue with this DAC. Now I can use my Nokia tablet battery for longer listening sessions.
Gice nice boost and clarity to your audio gear.
Worth the buy! Packs a punch, premium finish, should fit in any case you use. Especially good with the 4.4mm plug
I had a audiocular D07 dac 3.5mm, I needed a 4.4mm dac for my balanced iem cable ,then I bought Audiocular Note, it just gave a new bright dimension to the music quality ❤️🔥🔥, It has a customised software to get different equilizer, PEQ.If you are on budget and finding a dac ,just go for it,you won't regret it✌🏻✨️,Thank you The Audiostore .It's my 4th purchase from your site & I'm happy ❤️🔥

As an all rounder it fits my taste quite well,the only problem it really has is the male vocals being a bit recessed (not terribly recessed if you use vocal eartips),they are a tad bit overpriced seemingly,divine planar might be better,but for people looking for a fun entry into iem's,it's worth the price (some people say it's included DAC isn't enough,it works well enough as a temporary solution,yet to test if a dac makes a big difference or not).
Unsure if this is how most iem's are but the cable felt a tad bit short.
I had never used an IEM before, so this was my very first experience and I was genuinely impressed. As someone who loves music, I can confidently say this is one of the best investments you can make for audio quality. The sound is exceptional and absolutely worth the price.
To get the best possible audio experience, I would also recommend pairing it with a good-quality DAC, as it significantly enhances the overall output. ....
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.
