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.
Understanding Frequency Response
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.

Let customers speak for us
As a v16 owner this is a worthy upgrade .
Fit :
The iem is designed aesthetically that it fits like custom made
Sound impressions :
Treble is perfectly done with being sibilant, Mids sounds very organic and clear, Bass is the best part here it's a step up from their previous flagship v16.
Staging is better and so is the resolution, A total flagship level iem which punches above the price tag
Thanks to Pritam for his exceptional customer service and deal .
Definitely recommended
Have a great features and I am very happy after buying this m71 thanks audio store 🙏🙏
Time Spent with this DAP is more than 50 days, used many IEMs from Budget range to high end.
OBSERVATION & EXPERIENCE SO FAR.
- Wide soundstage, it's creating a spacious listening experience.
- Smooth and refined sound, with good bass & trebles. I liked it.
- little high Volume doesn't hurt ears because of spaciousness which this DAP creates.
- Main unique point is Vocals & Instruments separation, it's best.
- So far, I noticed Battery back up is really good. Will check it over time and provide feedback.
- Does not get warm that too after using for hours.
- Best software & Shanling Music app, it's very fast ( I use 1TB fully loaded Micro SD card.)
Please Note - Little more care is needed while handling as it has Glass tubes. Again it's unique offering & tubes makes music more enjoyable.
CONS-
1. Charging time ( it will get solve by software updates in future, Brand has co
nfirmed it in their post)
2. Only one colour option is available from Brand.
3. Some settings currently not present, Brand may add in future updates ( DSD gain Compensation, PEQ, MSEB, Night light short cut in quick pannel)
CONCLUSION-
a. Highly recommend those who want detailed & immersive experience.
b. THREE IN ONE- One DAP but three modes, all three sounds differently. One mode Transistor (without Tubes) and two Tube modes (Triode & Ultra- linear).
Sterdy & beautiful cable. I am using it with Hidiz MP145 Planner Magnetic IEM. It add details to music over stock cable. Makes all aspect of sound quality better.
I am writing review after One month regularly uses with my two DAP - Shanling M8t, Hiby R4.
POSITIVES-
1. Best Soundstage
2. Balanced sound
3. Musical & Makes music more enjoyable to ears.
4. No fatigue despite of metal construct.
5. Weight distribution is really good.
6. Largest Magnetic planner in the Category.
7. Details & instruments separation at best.
CONS-
1. Small ears may face challenge. Plz contact team ATS before purchase. Normal ear size, No issues with fit & long usage.
2. Stock cable is good but doesn't suit this IEM.
I am using this with Divinus Auram cable, which goes really well with this by appearance as well as by performance.
CONCLUSION-
1. Very very happy with the purchase. It's my main IEM in daily music journey.
2. My suggestion is Music enthusiast must have atleast one 'Planner Magnetic IEM', believe me I found that the the songs which I am listening since decades are sounding differently with some more details with this IEM.
The KZ Castor is an excellent choice for budget audiophiles. It delivers superb sound quality that rivals much more expensive headphones, with clear highs, rich mids, and deep bass. The build quality is solid, offering both durability and comfort for long listening sessions. At its price, it’s a fantastic value, outperforming many premium options. Highly recommended!
i think it's a great choice for someone who's just starting with the "iem" audiophile thing and it sounds good pretty good for the price range, it's sound clear and crisp, the bass is a little on the lower side but nonetheless great product if you are just starting, oh and yes the delivery was fast got it in a day.
Delivery was fast and item received was in good condition
Lets get to the point, its the best budget IEM!
I have been in the IEM space for more than 6 months and I was looking for a daily driver that can handle rough use, and then Pritam Sir suggested me 7Hz G1. And it failed to disappoint me!
A nice high quality well built iem, with one of the best ergonomic design, and a proper sound isolation with tons of tip to choose from.
The iem is well tuned with proper instrument seperation and clarity, warm tuning with perfect bass and excellent soundstage compared to other budget IEMs.
If you are new to yo IEM and want to buy your first IEM, blindly go with this! Trust me you would not regret! For 3.2k, its a steal deal!
(Pro Tip: Always listen to Pritam Sir's suggestions. He is the G.O.A.T)
We had an amazing experience at The Audio Store. Pritam, the shop expert, was incredibly helpful and knowledgeable. He patiently guided us through the world of in-ear monitors, explaining all the details and helping us understand what would work best for our band, Rhythm Freak. He suggested options that perfectly matched both our budget and our musical needs, making sure we got the best value without compromising on quality. Thanks to his expertise, we walked out confident and satisfied with our purchase. Highly recommend this store to any musician looking for top-notch gear and excellent service
