Dual Headphone Outputs for Versatile Listening
The M15i, equipped with four current mode amplification engines, supports both 3.5mm single-ended and 4.4mm fully balanced output modes. This versatility makes it compatible with a wide range of applications and devices, catering to various audio preferences and setups.
Crystal Clear Audio with Ultra-Low Noise Floor
Just as a pure black background enhances the vibrancy of colors, a low noise floor is essential for capturing audio details. The M15i boasts a high resolution that contributes to an ultra-low noise floor of -130dB, verified in Questyle Lab's testing environment. This ensures true high-fidelity sound reproduction.
Compact and Portable Design
The M15i's compact size makes it incredibly convenient for users on the go. Its portability ensures that you can enjoy high-quality audio anytime and anywhere, without the bulk of traditional DACs and amps.
Full Compatibility for True Lossless Enjoyment
Questyle Labs has optimized the M15i for compatibility with mainstream smartphones and tablets. It supports iOS, HarmonyOS, and Android versions 5.1 and above, as well as PC systems running Windows 10 version 18.3 and above (driver-free) and Mac OS. This broad compatibility allows Hi-Fi headphone users to enjoy lossless audio on streaming platforms seamlessly.
Apple MFi Certification for Enhanced Performance
The "i" in M15i signifies its Apple MFi certification, ensuring perfect compatibility with iPhone/iPad and the broader Apple ecosystem. This certification guarantees that the M15i meets Apple's strict standards for power consumption and compatibility, safeguarding your devices from potential damage caused by non-certified USB connections.
Dynamic Sampling Rate Display for Easy Monitoring
The M15i features a data status indicator that lights up during music playback. A single red indicator signifies PCM data with a sampling rate not exceeding 48kHz, while dual red indicators represent high-sampling-rate PCM data or DSD audio data. This feature allows users to easily monitor the sampling rate of their audio.

Let customers speak for us
from 4996 reviewsThis is really warm sounding as advertised. Especially vocals are more engaging. The fact that its driven by phone power doesn't affect the sound quality in anyway like in other dacs I have experienced brighter, thin sound or few peaks in upper midrange. If earphones are having good sensitivity then this dac provides good enough power. Although bit bulky build is very good. I'm sure it can withstand frequent drops also. Have not tried the filters and listening to default filter only. One thing I noticed is although on paper power output is good for 32ohm its only good at driving earphones and not headphones. Distortion kicks in when volume is increased even at high gain setting. I'm only guessing current supplying capability for dynamic driver headphones is not sufficient. Tested with 300ohm HD600.
The sound quality is so much better than any other wireless earphones
The quality of wire is superb.
The mic quality is also good.
Length and feel of wire is good. Sound quality with my Tangzu warner is excellent

Have bought this on 17 Aug 2024 and after using it for almost half a year i can surely say this is the best one in this price range...
I like how crisp and clear the audio is, also how good the IEMs respond to EQing, which unlocks a lot whole lot of possibility

Recently bought this after seeing some positive reviews
Fit:
Unlike many reviews which talks about it's fit issue, it's a wonderful fit for me with the stock large size narrow bore tips. I usually go for medium or small size silicone tips but for this one large one fitted well. i guess large size long stem eartips fits well with this iem.
Sound:
Vocals and string instruments sounds forward but never thin or sharp or fatiguing and has a sweet timbre. I guess it's due to its thick note weight and the quality of dynamic driver.
Bass in general is good. But i would prefer little bit more sub bass quantity. Also prefer the bass to be a bit tighter. Not too tight as i am not a fan of too tight bass. Basically here bass decay is slow and i would prefer it to be moderate.
Treble has just enough energy and details but relaxed.
Overall it sounds very nice with a pleasant timbre.
Note that i replaced the stock cable with fiio ls-b 4.4 mm cable.

Great set to start your tip rolling journey!
Got the delivery under 24 hrs.

This is wonderful product and quality is great. Very good working with mic.
And support samsung s22 ultra.
The Moondrop Blessing 3 is a hybrid IEM with excellent performance and a largely neutral sound signature with a slight bass boost. It offers impressive detail retrieval, resolution, and instrument separation for its price.
Pros:
* Excellent detail and clarity: It reveals subtle nuances in music.
* Balanced sound: Largely neutral with a well-controlled bass that doesn't bleed into other frequencies.
* Good technicalities: Strong imaging and separation of instruments.
* Comfortable for wearing for long periods
* Solid build quality
Cons:
* Fit can still be an issue for those with smaller ears.
* The cable could have been better.
Overall an excellent IEM for me.... Well done Moon drop!!!
The KZ ZSN Pro 2 offers exceptional sound quality at an affordable price. With a hybrid driver setup (1 dynamic + 1 balanced armature), it delivers a punchy V-shaped sound signature with deep bass, clear mids, and sparkling highs. The soundstage is surprisingly wide with good instrument separation and imaging. Build quality is solid, featuring metal faceplates and a comfortable, ergonomic design. While the cable and accessories are basic, the overall performance makes the ZSN Pro 2 a fantastic value for budget audiophiles.
Yes it is very comfortable 👍

Best under 2k for balanced sound.

Rarely do you find cases that offer this kind of value. I love it for two main reasons: there's no need to cram your IEMs like in typical compact cases, and it has enough room to fit a dongle DAC comfortably. You can even carry two IEMs if needed. The build is solid, and it feels premium all around. A great pick!

Suggested by Pritam—bought them and loved them. Insane value for the price! A must-have for beginners exploring the tip rolling game. While they mimic some branded ones, the material and build do differ—but the value is unbeatable. Highly recommended!

Purchased a iem from them.Nice packing safe delivery. Will definitely recommend beginner audiophiles to buy it from them.
