Introduction: Exceptional Closed-Back Sound
Who says closed-back headphones can’t sound that open? The closed-back HD 620S is for audio enthusiasts seeking a distraction-free listening experience without compromising on natural, airy, and detailed sound. Featuring a remarkably open baffle and angled transducers, it replicates the spatial imaging of loudspeakers while keeping listening sessions secluded.
Superior Design and Features
- Closed-back Excellence: Closed-back headphones with steel-reinforced ear cup covers for distraction-free listening sessions.
- Precision Sound: Reference-grade 42 mm angled transducers with a 38 mm diaphragm deliver speaker-like imaging with natural detail retrieval and an expansive soundstage.
- Enhanced Clarity: Ultra-light 150-ohm aluminum voice coil for enhanced clarity and accuracy in audio reproduction.
- Comfort and Durability: Lightweight chassis with steel-reinforced headband sliders and artificial leather ear pads with internal venting for long-term durability and all-day comfort.
Secluded Listening Experience
Enjoy undisturbed privacy while listening to exceptional open, natural sound. The HD 620S lets you experience detailed, spacious sounds like never before in closed-back headphones. The stainless-steel reinforced ear cup covers not only add timeless appeal but also provide a private listening session regardless of your surroundings. Ideal for those who prefer sofa concerts over kitchen talks, offering a distraction-free experience with true-to-life vocals and natural, airy sound.
Innovative Closed-Back Design
Open sound in a closed-back design might seem impossible, but the HD 620S makes it a reality. Combining the DNA of the HD 600 and 500 series, the HD 620S brings the best of both headphone families to a closed chassis. The reference-grade 42 mm angled transducers with a 38 mm diaphragm and ultra-light 150-ohm aluminium voice coil deliver exceptional impulse response, expanding the stereo image to an almost panoramic soundstage. This unique design preserves the detailed, smooth sound the 600 series is known for, setting a new standard for closed-back headphones.
Comfort and Longevity
The HD 620S offers timeless design, function, and comfort. The lightweight chassis is bolstered by premium touches that ensure its unique acoustic signature for years to come. Robust, steel-reinforced headband sliders and ear cup covers add long-term durability. In contrast, spacious ear cup covers and supple ear pads made from artificial leather provide superb acoustic isolation and all-day comfort. The HD 620S is ready for hours of fatigue-free, intimate listening.
Immersive Listening for Any Passion
Who doesn’t sometimes want to just switch off and become immersed in their own world undisturbed? With the HD 620S, you can stay in the same room without compromising on privacy or natural, expansive sound. Whether you love gaming, amateur music production, or simply listening to exceptional audio, the HD 620S elevates your experience with extraordinary detail retrieval and spatial awareness.

Reference sound in a closed chassis: The frequency is shown in Hertz (Hz) on the X-axis, with bass response from 20-300 Hz, vocal range from 300 to 3000 Hz, and treble from 3000 to 20,000 Hz. The Y-axis shows relative loudness in dB SPL. The HD 620S offers a bass response louder than the HD 600, resulting in a closer to neutral, true-to-life sound.

OUR HONEST REVIEWS FROM THE CO-FOUNDERS & AUDIOPHILES
View allTRUSTED BY OVER 35K+ MUSIC ENTHUSIAST
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.
