These have incredible balance all through the frequency range, and the best part about them is the soundstage, you have AN ACTUAL SOUNDSTAGE with these, an experience which you'll never get with most of the IEMs in this range. These have incredible GOOD bass, which is not boomy, but fun and engaging. These do not stuff you with detail in your face, but present them in layers, properly placed all through the space which they create. Which brings me to imaging, and these have the best imaging at this price, like I could point where which instrument lies where. The basic version comes with a just basic cable, which is basically crap, and qas quite awkward to fit in the earpieces,but works for me. Granted these do not have the best timbre, which is basically how natural they sound, maybe because of no cross-over between the planar magnetic driver & the dynamic driver, but these are DAMN enjoyable. Sometimes you need a different prespective for the music, which these bring in ample amount. Believe me, they're worth the money just for the soundstage, an experience which simply you do not at this price point. These are highly underrated, and far better than any chi-fi you may own.

I bought these few weeks back. The sound quality is awesome and better than many market competitors. It does not have a bumpy bass which many people will dislike it for . However, I like the crispy details rather than the heavy bass that Sony or Sennheiser products produce. The midrange is little thin as many have pointed out too. You can literally hear the holographic sound, each sound coming from different sources and angles. Also, these are plannar drivers. Hence, they require more pump to deliver proper sound quality. Don't expect the results using a smartphone. Thank you Headphone Zone for delivering these cute hearts.

Lastly Cons:
The cupid basics comes with thin Proprietary cables.
No compatible comply foam tips available at the time of purchase.

I ordered a bunch of earphones from headphone zone including all the BLONS, the Arias, and Thieaudio’s Legacy 2. All of them were nice and i heard great sound from all of them. I am a music producer but not an audiophile, at least i feel i dont hear the depth that others report that they can hear. I can hear the usual basic stuff of what makes music, the sound stage, the highs, mids and lows that depend mostly on the recording but now when I got my first cupids, they were defective and were promptly replaced with another pair by the company. Excellent customer service, but then coming to the audio, these Cupids made the sound fly. Forget about a soundstage, it became holographic that i can say only for these earbuds so far. The sound is light, airy, and dances with smooth bass and decent treble. All in all a very small package but these Taiwanese earphones have so far impressed me the most. I changed the supplied silicon earbuds to final audio large fit and they are a great fit since i didn’t like the supplied silicon earbuds. The cable is the only weird thing with its proprietary cable, but it sounds great if you can live with the basic package and its 3.5mm jack then the cable is a sweet deal. So far my FIIO BTR5 is more than enough to drive these Planars. All in all excellent dancing sound, and it has driven me to write this review, while i have declined to review the other IEMS as they all sound the same to me. But these Cupids really pack a punch. If at a later date i change my mind about the BLONS and Aria and Legacy 2, then i will write reviews accordingly. I haven’t even burned in these Cupids and they sound great right off the bat.
I have also ordered the Mangrid Teas and the 7Hz planar in USA and once i reach there i will be able to do more of a comparison on my FLAC files through my new DAP, the FIIO m11 limited edition. I used to be into headphones, but now earphones if they can be tolerated, then they are the best way to go. I always check my mixes and masters on my new earphones and they are spot on. Thanks so much to the other reviewers and I am pleasantly surprised by the thriving audiophile scene in India. Proud of all you guys who love sound so much!

At the outset a big shout out to the Headphonezone team for a blitz delivery and thoroughly professional service.
Now on to the review for the PRIME model :
Packaging : Basic and utilitarian.... nothing exceptional to write home about.
Accessories : Again it is basic and utilitarian. Good point is that there is 2.5 female to 3.5 male adapter which is very useful. The cable is of high quality and relatively heavy which establishes that the core is good. The quality of the accessories is top notch.
IEM : These are a unique hybrid earphones and also present a unique sound experience. This is nothing that one would have heard in the past. The sound is holographic which in my view makes the output more airy and sort of 3D experience. This having a Planar driver, I am taking Audeze iSine10 as reference for some comparison. The sound on oBravo is more airy and has better layering while Audeze has a wider sound stage. The difference in sound stage is only marginal. The bass is balanced and shade less than AudezeiSine 10. However, the experience is not short and has reasonably good sub bass and more natural representation. The impedance stated is 16 ohms but since it has Planar Driver, it requires a little more power to drive. However, it can be driven comfortably by Smartphones.
Overall, the holographic 3D signature is something which creates a niche for this IEM and in my view an IEM which should be part of your collection.

Overall :
Don't have much about the sound Quality, its not bad, it is as good as with
my ATH-M50x and Sony WH-1000XM3(not considering noise canceling).
Design :
It fit perfectly in my ear, but its heavy, and since my ears are small got a bit
trouble with ear over loop, so cant wear them in drop fashion. But I think I'll
get used to it, And I do love the all metal design so no complains about the
weight.

Sound wise cupid's are ok with punchy bass and bright treble...
But the proprietary cables are just a waste...
In my case... It doesn't least even 6 months...
One side is cable is failed to supply music to buds...
I have to shell out another 3000 rupees for cable which may not last another 6 months....

Headphone zone is very much straight line in dealing warranty service....a bit sad about that...

The Cupids are one hell of an addictive pair!! They definitely require amping to be enjoyed. The IEM is highly resolving and opens up significantly in terms of details when amped.

Sounds exceptional off the FiiO M11Plus LTD (DAP) stacked with Helm DB12 (Portable amp). The extensions at both ends (highs and lows) are phenomenal with a sweet mid range. While others have complained about the mids being lean, IMO the overall tonality of the cupids is excellent. The Soundstage is massive and is comparable to the likes of Campfire Solaris and 64audio Nio (which is crazy given the price of Cupids vs Solaris or Nio!!)

Although the stock "Whirlwind" tips are good, I'd recommend trying these with "Flare Audio Audiophile" memory foam eartips as they provide a far better seal. These tips don't dampen the treble which is usually the case with other foam tips like Comply, Newbee, Evidson etc...

My only gripe with these is that the mmcx port has this weird notch that makes it impossible to try other cables. The stock 2.5mm cable is excellent nonetheless.
