Pros: Nicely balanced; bass monster; big soundstage; very engaging; worth every penny if you are a bass head.
Cons: Bloated bass(can be ignored easily);will get sibilant at times; microphonics.
If you are looking for a bass monster, you should not overlook this earphone. The ''monster bass'' you are going to get from this earphone will not even be delivered by some expensive “headphones’’. I have owned many headphones and earphones over the years, and this is the earphone that comes back to my mind again and again. The bass quantity is just amazing without sacrificing the mids and the highs; a real pleasure to listen to with such a big soundstage and hefty bass. If you are fine with a little bit bloated bass and sibilance at times, then this is a great choice. This earphone has microphonics and I don’t recommend this if you are running around ‘’all the time’’,haha. At home, it is very fun! I didn’t have any fit issues when I first tried it. It is a given that everybody is not going to like the way it fits in his or her ears.
It has its issues, but the” very sound’’ with that kind of thumping bass made me forget everything. It sounds just fine out of the box and I didn’t notice any tremendous change even after burning it for 100 hours. All in all, it feels like you are in a party hall with some very loud enjoyable music. Everything is just going sound very big.It is not just about quantity,it screams quality too. When I switch from this to DUNU Titan 1, Titan 1 sounds like a kid. I highly recommend ATHCKS77. After this, I even bought IM70, but I didn’t like it; I returned it after trying it for a couple of days. There were lots of glowing reviews on IM70, naturally I fell for it. The IM70 was neither fun nor engaging. The IM70 may win in retrieving details, but in the ‘’fun factor’’department,the ATHCKS77 takes the cake. The IM70 sounded flat, dry and boring. Again, this is just my opinion, so take it with a pinch of salt. You are not going to get a world-class sound, but it is worth ever penny. You have to hear it to believe it.
Make sure you play around with the tips till you get a nice seal and expected sound quality. If it sounds thin, then something is wrong either with the tips you are using or the seal itself. You may even have to buy a new pair of ear tips.
The mid-range is full and doesn’t lack in any area. Female vocals ‘’will’' get sibilant at times.
The highs are nicely done and very enjoyable to listen to; I mean for the price you pay, you can’t simply complain here. I can nitpick here too, but I am not going to as I really love this earphone.
With just 16 ohms and good sensitivity, you can run this earphone to ear-bleeding levels. I don’t recommend any amp for this. Yeah, it is that good! You can drive it with just about any crappy phone.
This is the only earphone, along with Sony XB90(I like athcks77 a bit more than xb90), that has completely satisfied my basshead zone without sacrificing the mids and the highs. An astonishing earphone for the price you pay! I am going to buy another pair shortly.
