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.

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.

Kudos to makers/seller for making it to available.
Purest form of audio hearing experience with this cable.
Happy with the purchase.

The build quality of this cable is top-notch. I’m using it with my HD560S connected to a laptop via Apple Music, and the difference is noticeable. The bass feels tighter and especially welcome improvement for openback headphones and there's a clear boost in instrument separation and overall clarity. Upgrading to a balanced connection has definitely proven to be a worth while decision.

The Hisenior Mega5EST is a reference-quality IEM tuned with taste and subtlety. It doesn't shout for attention but rather invites you to listen deeper. If you're looking for an IEM that balances technical excellence with musical emotion, this one is a rare gem in the hybrid space. A true “listen for hours, forget the gear” experience.

This is the best MP3 player you can get for this price.

I'm new to the world of IEMs and this one was bought to try how it feels. Trust me, it won't disappoint you. Double the value compared to headphones of the same rate.

Budget king SMSL RAW MDA1. Very versatile music dac & headphone amp. Fully satisfied. Being an audiophile I was searching for best budget one got this from The audio store. Thanks for timely delivery. Nothing can match it at this price range period.

Works well with my Moto Edge 50 Pro. Other DAC's would have a lot of interference and static, the Moondrop Echo A has none. Audio is clear and the connector does not heat up at all. Battery life isn't impacted as well.
The build quality is excellent, cable is flexible and will fit in any iem carry case as well.

This is a great product with excellent sound quality. The bass is impressive and it's worth the money.

Beautiful and heavy duty balanced cable. Adds a weight to the music's bass i.e. tighter bass response.
Good product excellent sound well packed but delivery was delayed by two days.otherwise everything good.

Combo of cx31993 max97220 chip is more than sufficient to drive any iems

Using it with truthear crinicle zero red and works perfectly. Loving it

I’ve been thoroughly impressed with the SMSL RAW MDA-1, especially as someone who values Hi-Res audio and the transformative power of a great DAC+amplifier.
The build is solid, with a sleek, compact design that fits perfectly on my desk without taking up too much space. I love the variety of connectivity options—USB-C, coaxial, optical, and Bluetooth—making it easy to connect to my PC, gaming console, or even my phone. The Bluetooth feature is particularly handy for wireless listening when I want to move around without sacrificing sound quality.
One thing I’ve found is that it’s exceptionally well-suited for low to medium impedance headphones, delivering plenty of power and clarity. However, if you’re using high-impedance headphones, you might notice it struggles a bit with volume, so you may need an external amplifier for those. Also, while the 4.4mm headphone output is convenient, it’s not a true balanced design, which might be a letdown for audiophiles who prioritize that feature.
Given its price point, the SMSL RAW MDA-1 offers exceptional value, delivering high-end features and performance that punch above its weight class. It is particularly suitable for audiophiles and gamers seeking a high-quality desktop audio solution with both wired and wireless options. However, for those with high-impedance headphones or a preference for advanced sound-shaping features, it may fall short, potentially requiring supplementary equipment.

KZ Castor Harman Target with Improved Bass is just bliss for listening to music & watching movies.
I play lots of pc games, this IEMs are just awesome for gaming.. The sound stage is fantastic 🔥🔥. Loved using it for movies & games ❤️🔥🤩

It's simply wow
I discovered new things in my favorite audio.
That's how good it is.
