Quick impressions - Fully burned in - all final impressions are with the supplied comply tips
General music repertoire: Rap, classic rock, hard rock, metal, pre 00s pop, occasional instrumental or classical
Story time:
Unboxing experience was alright given the price point, I am familiar with obravo's higher end packaging (Ra) and obviously this doesn't come close, but everything needed was in the box which was pretty handy
I went straight for the medium comply tips, and they were much stiffer than my usual compy tips that I daily on my acoustunes, and initial sound before burn in was interesting to say the least. the classic obravo sound was there (hard to explain, but if you know, you know) low end slammed like drummers were sitting in your ear canal, and highs were pretty crisp.
It took a great deal of burn in to reduce the recessed mids (mids would just sound like they were in the wrong place), but it got sorted out (mostly)
I tried out the supplied 3.5mm cable - it was terrible, which is strange considering the same cable comes with most obravos, not sure why the supplied one was so bad. Without going into great detail, it completely un-obravoed the sound
Next I tried some tips, softer foam tips (that I usually use) didn't manage to seal in the bass and only made the mids worse. I then tried every supplied tip, some led to some interesting sound profiles that I recommend trying out - they weren't for me. The most interesting tips I liked were the Senda Alza tips (which are pretty famous for being great tips) but nothing came close to the supplied blue comply ones.
2.5mm cable was miles better than the supplied 3.5, at the loss of some comfort, the connectors are very long and poke out much further than they should before wrapping around the ear - this is the case with obravo mmcx cons in general, but hey, it sounded fine
The supplied 2.5 to 3.5 adapter is decently high grade and I heard no sq loss or changes when using it
After all of this, I burned the iems in for over 100 hrs
Impressions:
Solid, given the price point. The low end is what you would expect from obravo, but mids still suffer after a great deal of burn in - I will try using a cable with a different impedance at a later time and hope that can resolve it further.
Sub bass is good, very responsive and decisive - the decay is very fast and it sounds great when listening to (real) drums
Bass is spectacular (with the stiff comply tips) - Bass guitar reproduction (as well as normal guitar) is exactly what I was looking for from a planar driver
Mids aren't great, they're definitely there, and in some tracks - sound perfect, while in others it will sound too recessed or just in the wrong spot
Highs are good, like the sub bass, decisive - but not sharp enough to annoy. These are much easier on the ears for treble heavy tracks versus my daily 1650CUs
The overall sound profile is unique, as to be expected from obravo - some of their iems sound like speakers, and some simply can't be explained - these sit somewhere in the middle
From a clean SS source (Plenue 2 or ADI2 iem port) they are great - but do ask for quite a bit of power to shine, on some tracks the iems are lively and you'll find yourself lost in the music tapping your foot, while on other tracks they sound a little dry and boring
From a clean tube source (Lyr3) these sounded spectacular, and I will be looking at getting my hands on an alo CDM specifically for these iems. If you have access to a tube amp with low enough noise to drive iems, please give it a try. I found myself sitting at my desk preferring the cupids to my ether c flows
Soundstage is on the high end of good for a closed iem, with a spacious +5 inches in all directions for normal recordings (instead of forced far away sounds) Soundstage opens up even more on tubes as expected. Imaging and clarity seem to not suffer from this soundstage, intimate recordings have great imaging, and standard ones seem to be handled just fine
TLDR:
unique sound
very fun listen
recessed/lacking mids
2.5mm cable good sound, poor comfort
3.5mm cable poor sound, good comfort
pairs well with a variety of sources
good soundstage
shines on a tube amp
fiddle with tips
GREAT VALUE!
