I bought these earphones after hearing lots of positive reviews from raghav and his team.
But these earphones ended up sounding like jbl c100si which is half the price. Plus there is distortion and crackling at higher volumes.
THEY WON'T LET YOU RETURN THE PRODUCT REGARDLESS OF ALL THE FAULTS. YOU WILL BE TRAPPED . IT'S BETTER TO BUY FROM AMAZON & FLIPKART WHICH HAVE EASY RETURN POLICY.
My ₹1199 got wasted and now I am trapped with this product.

Sound:
They sound good out of the box. Great for people who hate the traditional V sound found in Chi-Fi audio products. The earphones are not particularly loud like many of those IEMs, but gets loud enough. The loudness is only an issue if you EQ them and have to apply a bit negative of pre-amp. With slight EQ these can sound even better by reducing the ever so slight bump in the mid bass region. The sub-bass is very faint on these, even with EQ you probably won't achieve a clean sub-bass. But it should be alright since this product does not seem to be intended for bass heads.

Comfort:
These are extremely comfortable to wear. They sit deep into the ear canal and with the right sized tip the isolation is great. They are very light and can be worn during daily commute or in bed while sleeping. The 5 pairs of tips they ship with are of very high quality as well.

Build:
This is where they cut corners with this product. The cable doesn't feel particularly strong and might fail if used without care. The junction between the bullets and cable is not reinforced and may become a point of failure.

Conclusion:
Buy it for the sound, ie. realatively balanced tuning. EQ a bit for best experience. Use it with care.

The earphones didn't come is a good packaging as I was expecting, as I love to keep the box in which they come in. But even though the box was squashed the earphones did come undamaged.

Coming to the Design, they are Okay-ish, not much fancy looking. Even having a plastic body the earphones doesn't feel cheap in hands though, but still a metal body would have been real good :))
They are comfortable to wear, provided with the replaceable eartips , it is provides perfect fit for the recommended ear.
The earphones have the annoying type of wire, if they touch something you can hear the vibration, which is real annoying at times.

Coming to the soundstage of the earphones, they provide really balanced audio, the mids are really defined, even though bass is not that good, but the overall audio is detailed good.
I have just listened to music using my phone and laptop (apple music, spotify), so listening using a dedicated DAC might change the experience.

In conclusion, this IEM is good at its price. But it could have been better if the price were a bit lower. ~\_:)_/~

Ive heard and owned some very high end headphones(hi x55) and iems (ath e40, it00) along with avg consumer earphones(sony)
My verdict:
Very very good earphones, but too pricey for 1.6k bucks

Pros

Zero distortion even at full volume and even when listening to complex tracks
Great clarity
Very good seperation of instruments
Laid back, non fatiguing
comfy buds with a comfy sound.

Cons:
Slight hollow/unnatural timbre, The instruments and voices could use a little more heft and warmth.
. Super fragile
.no mic
.non detachable/replacable cable

So should you get em?
Id say compared to many other earphones in this price bracket they are probably better of the bunch than most. but the non detachable cable and their fragility and the not so wowing but comfy sound makes them a pinching deal at their very high price especially because sony offers the mdr ex 155 , ex 150 with mic, at 500 rs lesser the cost and these are very comparable to them sound wise. So nothing special for your 1.6k rs.

Eartip enthusiasts, you may get em but remember dont get them just for eartips cause they make a very subtle difference, probably even placebo at this rate lol.

General healthy advice for audiophiles:
More expensive never means better, Ive heard too much expensive shitty audiophile gear that made me hate myself for buying it.

More drivers, dont mean better sound!
Infact Single drivers can produce a more cohesive and natural sound, a well designed single Dynamic driver can outperform a half assed balanced armature or 10 of them any day.

.Comfort matters!
poorly fitted gear= bad experience(doesnt matter how good it sounds)

I finally got to try Final E500. They definitely need more Power to sound the best, stock mobile output will not be enough.

-> Sound is Balanced with a little dark tuning - meaning If u don't like spicy / sparkly treble or upper frequencies these iems will be amazing.

This is my favourite tuning, I really like it. I was soooooo happy I could finally get them.

-> I am not talking about bass coz there was channel imbalance.

-> Iems are very small(tiny), light weight but cable is where they cheaped out on but considering price I'm not complaining.

Thanks for making these available hpz team

Being an Audio Technica fan boy for almost a decade, I was skeptical of ordering these new pair of Final E500 headphones. I needed a good pair of headphones in a tight budget with balanced Mids. I decided to give it a shot and order this. To be honest, I had very low expectations. When I got these pair of headphones, it just blew my mind. The sound quality is on par with headphones that cost twice or thrice as much.

I am completely satisfied with the sound quality of the headphones. The only thing I am concerned about are the cables. I just hope that the earpiece end of cable survives. Other than that, I absolutely love the headphones.

I have used the moondrop quarks previously, these are definetly better than those. Really good for the price and much better than the average boat earphones. They are quite comfortable as well as due to the small and lightweight housing. Overall a good buy.

Sound is amazing . Mid n treble boosted. bass is little less .
But sound is really good
