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.

Love these, u shaped sound signature but pains my ears after 2 hours of listening.
The IEM's have a decent balanced V shaped profile & the manual EQ settings are quite useful.
After my first pair, the Oriveti OD200 (which I loved!), I grabbed the Martilo as my second set, and wow, I finally get what people mean by basshead. Guys, these are unreal. If you listen to music that's supposed to really H-I-T, this is the one for you.
Sound Breakdown
The Bass is the star: It literally shakes my eardrums. We're talking deep, physical sub-bass rumble, not the muddy, boomy kind. It feels like having a huge subwoofer in your head. It hits hard but stays clean and super fast, which is critical.
Mids are surprisingly clear: I was worried the bass would swallow up the vocals (Mids), but they stay right up front. My favorite singers sound crisp! You get great separation, letting you pick out instruments even when the bass is going crazy.
Treble is sparkly and quick: I think the planar driver is what makes the high notes (Treble) sound so detailed. It adds enough "air" to the sound and keeps the whole picture from feeling dark.
The design is awesome, they look like cracked lava rock, and they are pretty comfortable even though they look a bit chunky.
Only 1 downside for me was the eartips, it could be more comfortable given the price tag of this IEMs. I'm using stock eartips of my another IEMs (Oriveti OD 200) which is surprisingly comfortable.
Final Takeaway
If you are moving up from entry-level and want to know what truly clean, hard-hitting bass sounds like, get these. It’s an easy, near-endgame fun set for people who love bass-heavy genres like EDM and Hip-Hop. Go listen to them!
Works great for any iem out there. I previously only religiously bought apple dongles as my got-to portable dac. Only later I found the audiocular spark which had the CX31993+ Max amp and provided slightly more power. It works exactly like it says and gives 1.4 v vs the 1 v of the apple dongle. So if some extra power is what you’re looking for, the audiocular spark is what you need. This is going to power all your iem needs.
I love these iem’s . This is end game iem for me since expensive ones have diminishing returns
I really like audiostore delivery
Awesome purchase. The KZ Castor Pro Harman Bass Tuned is a dream for audiophiles which will make them enjoy the nuances of every genre of music. Loved it. Wow.
Spectacular DAC, boosts the audio well. Great music experience.
TL;DR:
Finally jumped into the IEM world with the Bunny and I am blown away. Super clear highs with zero harshness, smooth vocals, and punchy bass. Works great across all genres I listen to, super comfy, and keeps getting better over time. Only downsides: cable’s a bit short but that is subjective and movie audio can be hit or miss. Overall, I’m honestly blown away by how good these sound for the price.
I have been contemplating getting into the IEM world for the past few years and when I finally pulled the trigger on this one, it just blew me away and I am not even exaggerating. Before getting these I was using OneOdio Headphones that I got for 4k that I still love but, well, when I got the Bunny's I was like, is this what have I been missing out on ?!?!
This long contemplation for getting an "IEM" was also because of conflicting reviews about some of them like some having high sibilance or thin sounding bass or something else and I couldn't make up my mind to get one or the other. I'll be honest, I was kind of scared if I might not like these or I might find them too sibilant as I am pretty sensitive to that, and I was already expecting the bass to be less than what I am used to before hitting the play button. All of my worries went away as soon as the music started, the highs and vocals were absolutely clear and bass hitting just right. I did try tip rolling to see which eartip gave the best seal. I don't know if burn-in is real or not, but it has been a month since I got them and they have just kept getting better and better.
I listen to a lot of DnB, Experimental or other EDM subgenres along with Jazz, Orchestral, Movie scores and songs with vocal etc and they work for all the genres in such a nice way! I'm seriously trying out new genres at this point because everything sounds so fun with them. The vocals are so smooth and just the right amount of sparkly and the bass either the sub or mid is not at all lacking by any chance. I won't be able to talk much about the soundstage but if I say so, listening to Yosi Horikawa, Snarky Puppy, Tipper is an absolute fun in these. Everything just sounds like it is there as it should be. Separation is great compared to my headphones. I am indeed hearing things that I haven't before but that might also be because of the bass not muddying everything up.
They are small so they fit me like a glove (subjective but still) and are so comfortable to wear for a long session or even while lying down. I just wish the cable were a little longer but its still fine. The included bag is pretty handy and the included tips have a pretty good selection to get a good fit.
I'm definitely getting a DAC and maybe in the future a Balanced cable just to see how much can these be pushed and what sound these can deliver.
The only few things I'd say is that watching movies or shows could be a hit or a miss with these because of the way they might be mixed/mastered and as these being balanced they don't hold back on any frequency or muddy up the other. The other day I tried to watch Chris Nolan's Tenet with this, but the gunshots were a little too harsh or the voice was too low to hear properly but Ford vs Ferrari, Mission Impossible or Star Wars were very fun to watch. Might be a subjective opinion but I thought I'll add it. The other thing is that I thought these would be good for making music as I do that for hobby but I still have to test them out more in that scenario.
It is very efficient and clean sounding. I loved the amplification which is enough to drive demanding planar magnetic headphones. The functions and display is very intuitive. Overall a very good product.
A goodpurchase awesome improvement in the bass with no extra noise!
It is really good for the price
The IEM's are really good. The build quality is great for the price
I am using this for my daily use. This is so good even tunable to an extent. Good quality build and audio
Best in class adapter for various IEM's. I used it with KZ caster, Fiio JD1 and KZ ZEX. All works perfectly. My choice currently is with KZ ZEX. Instead of Touch, button system to control is too good and easily fits in our ear. ANC is not too aggressive, but quite good. Transparency mode is effective. So finally it's a perfect buy for our IEM's. KZ Rockzzz.
Got this over Waner II and Bunny DSP and it was totally worth it. Loving it so far. It supports my s21 FE and Lenovo LOQ Laptop. Let's see how long it lasts.
