To give you a background, i have never been into iems. Don'tlike the hassles of finding a perfect fit with so many combinations of tips and flange etc.I love my open back headsets and for portable i do have a vast array of earbuds to choose from 
.
On the topic of portable use,earbuds with few exception do falter to reproduce a very clean and tight bass.So i finally decide to get the magaosi k3 pro pro(they seemed interesting and it was 11.11).Surprised by the way they sound,till date they have been my go to portable iems. Very good low end reproduction and almost an unbelievable sound stage in them.But mids and treble left a lot to be desired(treble especially).
The K5 seemed interesting to me being a 5ba and custom headphone.I decided to pull the trigger and order them from Penon during the new year sale and been happy ever since the day i got them
**These are my views of the iem,based on my impression on the bench marking tracks that i use.Your experiences may differ.I am no expert and they are my own view(not guided by any seller or manufacturer)
Whats in the box??
How do they Feel??
In a word "awesome".By far the most comfortable iems i have ever worn.Tried a lot of iems,you always have to experiment from regular tips to foams to double and triple flange.I faced similar issue with the k3 pro also.
The K5s impressed me in this regard.They fit so well right out of the box.And a lot of friends tried them too,with no need of any change(except the one case we needed a larger eartip).Its a snug fit and extremely isolating.Sometimes i do feel its constructed for my own ears(that maybe exaggerating),but that how easily they sit on your ears.
Sound
I have my humble lgv20 for them and they do work well for me(Running uapp with the v20 and tidal).
Did also try them with a desktop setup and it does bring in a lot more details in the treble and improved dynamics.
Bass:-Very tight and well controlled bass as expected from an iems. And its a very linear bass too.But it does not slam very hard and extend very low .Its a very linear low end and may not be to everyone liking.Though with the mimby i did find a significant increase in slam.
Mids:-
Exceptional mids here,nothing to complain about.Vocal heavy tracks are a treat to listen to in these iems. Very forward mids,with both male and female vocals sounding very smooth and organic with no bleed form the low end .The thing you notice coming from k3 to k5 is there is no veil,its brilliantly transparent across the mids.
Treble:-
As i told k3 left a lot to be desired in terms of treble. K5 is a vast improvement,but you do realize there is a treble roll off.How aggressive is it ?...not very i would say,but it would again depend on where your coming from.If you like sharp and a bit bright sound,k5 can leave you disapointed. For me,though i use a hd700 and 6xx i am perfectly alright with the k5 treble response.You have to keep in mind these are going for the "custom headphone" for a comfortable iems you cant risk a harsh and fatiguing sound.I am perfectly alright with the treble signature of this iem,makes for long listening session.Though a part of me desired for more air and sparkle in the presentation.
Sound stage :-Overall sound stage is quite good(doesn't have the very large sound stage of my k3 pros)..But the depth of the sound is what impress the most.I see a lot of imaging and separation going forwards and backwards also sideways(of-course) in these iems
**The iem does benefit by driven from a nice DAC. Going from the lg v20 to mimby did clear a lot of the treble and low end slam.
Verdict:-
These are quite a unique iem to me.They are not perfect,the bass and treble would not be to everyone liking.But for the custom fit and comfort and the exceptional mids,i would pick these anyway. The interesting comparison would be with the fiio f9 pro and the rose br5(have not managed to get one for review yet.)As soon as i get my hand on one will do the comparison.
**Yet to try out the Bluetooth adapter(have no inclination to go wireless on these
)

Whats in the box??
- The box has a nice premium design,and its very aesthetically pleasing to see to the transparent earphones on them
- They come with a simple yet very function pouch(wish it had been a bit more spacious to carry spare cables)
- The cable in the v2 is something to behold,very premium looking and a good sturdy feel to it.
- Bluetooth adapter cable--not sure about this one....not sure if it was absolutely required.I would have been so glad if this iem costed say about 30 $ less or came with a spare mmcx cable like the one provided. Don't think these are the sporty,waterproof kind of iems,i could be wrong maybe you can.They sound so very good i always want to plug it to the best source and that's never Bluetooth
