Description
The benchmark of audio quality is here with the Sennheiser HD 650. This open-back headphone is designed to reveal the true potential of a recording and bring out every nuance in it. From the first note till the last, the expertly balanced acoustics ensure a musical, non-fatiguing sound. The luxurious construction makes it comfortable for long listening sessions as well as durable to withstand studio tantrums.The Master of Music
Enjoy your music with no barriers in between with the Sennheiser HD 650. The 42mm driver has been specially tuned for critical listening. The 38mm diaphragm and aluminium voice coil ensures effortless treble and bass with lifelike mids. Each driver has been perfectly matched to keep both channels consistent throughout the frequency range and reduce variance. This and the open-back design ensures a spacious audio experience that’s independent of room acoustics or loudspeaker positioning.
Made for More
The Sennheiser HD 650 is designed for more – more details, more musicality and more time for monitoring. The signature sound starts with our in-house acoustics. The open-back design allows ample room to expand every soundwave for a smooth response and dimensional soundstage. The headphone truly performs at its peak with high-resolution sample rates, without over-hyping the treble range. It’s hardly a wonder that this gem is a trustworthy addition to any studio professional and audio lover’s collection.
Has All the Powerful Connections You Need
From powerful headphone amplifiers to DAPs to computer-based workstations, the HD 650 is designed for these and so much more! The detachable, impedance-matched cable has ultra-low capacitance. It measures a length of 3 metres (9.8 feet) making it easy to move around while listening. The audiophile-standard 6.3mm (¼ inch) connector can connect to most devices. For the rest, the 6.3mm to 3.5mm adapter works like a charm.

Sennheiser is a well-known brand in the audio industry. They offer a wide range of products catering to both audiophiles and casual listeners. Their products include open back and closed back audiophile headphones, in-ear monitors, ANC headphones, and true wireless earbuds. They are known for their exceptional sound quality and durability. Whether you're a professional musician or just a music enthusiast, Sennheiser has something for everyone.
I am big fan of Sennheiser neutral sound, previously was using HD598 for more than 5 years until the ear cup worn out. After that, tried multiple different headphones & finally settle back to the Sennheiser sound with my new HD650. Listen to it all day without any listening fatigue. Sound signature is neutral with good instrument separation & places the vocal in forward while the instruments in the background as it is supposed to be.
Wanted to buy one and very much happy with it.
HD650 is must-have headphones for music lovers
-Good build
-Comfortable
-TOTL sound In budget
Sound:
Orgasmic vocals, decent soundstage, and good clarity especially in newer Romanian manufactured units!
It pairs best with tube amps
For HD650 I have a xduoo mt-604 tube amp and a zendac connected to PC
To get the best experience on my PC, I turn on truebass on zendac(set it to variable mode) and I turn on Dolby access movies with warm profile
Now the sound is more fuller, it has more body and bass also is much warmer and orgasmic!
Also, I don't feel like getting a DV sooner after doing this setup! ✌
I was excited to see this, Headphone is flat in frequency response. And yes it is very detail in all frequency spectrum! Its worth the price.
I was having problem translating my mix on other environments than my room. This HD 650 just shows you what you are missing and what you are gaining. Great for Mixing. Works Great with sonarworks!
Its just for music enthusiasts. Not for tracking though.!
Thank You Once Again!
An amazing sounding pair with beautiful and lush mids, sweet sparkly treble and an intimate soundstage which emphasizes the vocals with a big image. Pairing it with the Honey H1 from the balanced out and loving the sound a lot, the bass is tight but never boomy, a perfect portable companion for an open back and I wonder how it scales up with a good OTL. A must have HP for a laid-back and smooth sound. Kudos to Pritam for the superfast delivery!
One of the best headphones out there .period. A lot has been said about these clean ,soulful performers. Drove it with the dragonfly black and tempotec hd pro with my laptop and smartphone and also thru shanling mo and sony NW a 55 which is the gear I have. Heard 24bit wav files mostly Ilaiyaraaja songs.Instant difference was there . You can hear with the above devices too ,but they drive only at the topmost volume which is just enough if you don't have any other amp dac. Am shopping for a suitable amp and dac for these. Clamping force is high initially so needs time to adapt .Shall update after I use with proper amp dac which most of the users recommend. Audiostore delivery was fast and well packaged.

The carry case is spacious enough for keeping one IEM and one small portable DAC with cable. Like I have kept Muse M4 dac with dihifi cable and one IEM in it. And the shell is hard so no chance of anything happening to the IEMs.
Was the cheapest option for a replacement cable I could find anywhere. And it works flawlessly too, no complaints
Amazing product
I recently purchased the Castor Pro KC earphones, and they have exceeded my expectations. The bass is deep and punchy, yet it doesn't overpower the mids and highs, ensuring excellent instrument separation. The tuning switches offer great flexibility, allowing me to customize the sound signature to my preference. Build quality is solid, and they are comfortable for long listening sessions. Overall, these IEMs deliver an impressive audio experience at their price point!

Very good cable
Works with 0.78mm 2pin iems
Using LG g8x thinq and output is higher than the smartphone's 3.5mm output.
Moondrop Link app works well, except a few buggy connectivity issues.
Good to see that one can create any Eq profile and save it in the app as long as it's done within the parameters. Very well executed.
KZ Castor Harman Target Version – Review
Design & Comfort
Lightweight, durable, and comfortable with a detachable cable. The in-line mic is useful for calls and gaming.
Sound Quality
Bass: Punchy and deep without overpowering.
Mids: Clear vocals and instruments.
Highs: Crisp but slightly bright.
Soundstage: Decent separation for immersive listening.
Pros:
✔ Enhanced bass
✔ Balanced tuning
✔ Comfortable & durable
✔ Affordable
Verdict:
A budget-friendly IEM with great sound and comfort, though the mic is just decent.
I'm using first time DAC most of the people refer this varient, difference between 3.5mm jac and this DAC D07 is absolutely awesome, so much details in hearing a song and music, loved it ❤️❤️❤️❤️👌👌👌🙏🙏🙏
Solid pouch
With good space
The product is worth the money
And I personally love the your faster delivery service
I got the product just in with 30 Hrs

I like Moondrop ECHO-A Dac. It is not powerful Dac but it produces quality sound .

Great for listening to all music genres, gaming on PC or consoles or pretty much any thing you'd like to do with a pair of earphones.
Superb packaging 👍🏻 delivered what was promised.

I recently got my hands on the ROSESELSA AURORA Ultra IEM, and I must say, it has exceeded my expectations! For under 2,000 INR, this IEM delivers exceptional value and performance that can easily compete with many pricier models out there.
What really stands out to me is its versatility. The AURORA shines across all genres, whether I'm diving into classical symphonies, jamming to rock anthems, or vibing with electronic beats. The sound quality is simply fantastic, making every listening session a joy.
A cherry on top is the comfort factor—these IEMs are small and lightweight, so they don’t cause any discomfort during long listening sessions. If you’ve had issues with larger IEM shells in the past, you’ll find the AURORA to be a perfect fit. Plus, the cable quality is impressive for the price, adding to the overall value of this product.
To unlock the full potential of these IEMs, I highly recommend investing in an external dongle. I personally use the Kiwi Ear Allegro Mini DAC, and it has truly elevated my audio experience. If you're on the hunt for a budget-friendly IEM that doesn’t compromise on sound quality, the ROSESELSA AURORA is a must-try!
I also want to take a moment to thank the audio store for their outstanding service. My order arrived in perfect condition, and their customer support team was incredibly friendly and helpful. Overall, this has been a wonderful experience, and I’m absolutely thrilled with my purchase!
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 🙏🙏
