Description
- Massive power and superior sound from a sleek and stylish chassis: The EF400 is the modern desktop DAC/Amp solution, with a compact footprint and price to match, but with sonics that outperform products many times its size. Ultra-high efficiency and low power consumption at maximum stability:4.4W per channel balanced output. Embedded with HIFIMAN HIMALAYA R2R DAC- Recipient of 2022 VGP Gold Technology Award (Japan).
- Experience the prized performance of the R2R DAC: HIMALAYA is a discrete R2R DAC (digital-to-analog) module that is based on the FPGA algorithm. The combinations of its low audio frequency range, out-of-band noise, and low energy consumption make it a perfect match for high-performance audio equipment. The HIMALAYA DAC module supports the standard PCM music signal transmitted by the most common IIS (Integrated Interface of Sound) audio interface, with a maximum resolution of 24Bit.
- Full Balance: The four-channel differential structure features a DAC, buffer and active filter that add up to unbeatable fully balanced output for stunning performance from a Class AB DAC/amplifier. The four-channel fully differential amplifier circuit features a maximum output of 10.7 Vrms (THD<1%) on a 36Ω resistor equivalent load. The result: fully balanced output that is beyond compare.

Let customers speak for us
from 5011 reviewsThe Sennheiser IE 200 delivers impressive value for the price. Comfort-wise, they’re lightweight and fit snugly thanks to the ergonomic design and included foam/silicone tips—great for long listening sessions. Build quality is solid despite the plastic housing, and the detachable braided cable adds durability. As for the sound signature, it’s balanced and clean—tight bass, clear mids, and smooth treble without harshness. Bonus points for the dual-tuning feature that lets you slightly tweak the sound. A fantastic entry-level choice for anyone looking to step into the audiophile world.
There sound is pretty good
Good quality
a very well made cable from Dunu with modular plugs and a very secure fastening system (q lock), no microphonics noted, contrary to many reports, usage : Shure se215 + 4.4 plug + Hiby r4 and it really opens up the Shures and the over ear loops are very comfortable too
This 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 👍
