I have to say, I am a very big AT fan ever since I bought the M50s monitors and I also bought the in-ear diaphragm earbuds, which I also think were great for the $30 I spent on them. I also own a pair of klipsch s4i as well as a pair of sennheiser cx 300B mk II ( which i was very disappointed with becuase thely lasted about 4 weeks before the left ear bud shorted out...I actually thought the sounds and design was great until my pair crapped out just after the return/exchange window expired).

Sonically these have huge, crisp bass, very clear and detailed highs and mids. I mainly run these through my galaxy S3 with poweramp, which has great customizable eq settings and I mainly listen to vinyl FLAC rips betweeen 16/44.1 to 24/96 encoding quality... I will say that for the price, these come very close to the m50s in terms of detail, soundstage and balance. I do tend to eq based on the particular album and i usually have my preamp turned down because these are nicely driven...comparatively to the s4is and the AT in-ear diaphragm headphones, which in my opinion are very close with AT taking a slight advantage in the mids and highs, these are far superior in every facet. So while I have never owned a $300+ pair of headphones, I'd say if you are on a budget like most of the world and are in the market for a high-quality pair of earbuds, I give these my full endorsement. I haven't had them for a very long time yet, but based on my last pair of AT buds and monitors, I expect these to have great longevity and durability...I will update if that changes.

Notes: I really like the way these fit in my ear (which typically are not well-suited for earbuds).

Introduction

First off, I'd like to thank the folks at Audio-Technica once again for providing a review sample of the CKS77.

Having reviewed the Solid Bass line of portable headphones, naturally, my next stop would be the Solid Bass line of earphones. This time, I'm starting with the CKS77 in ears, not the cheapest or lowest end Solid Bass earphones but on the lower end compared to the CKS99 and CKS1000. So, does the CKS77 measure up? Read on to find out.

Accessories: The CKS77 comes with four pairs of silicone eartips, a set of manuals and a drawstring carrying pouch.

Design and Build Quality: The CKS77 is one of the funkiest designs I've come across in an IEM. Similar to the Thermaltake Isurus, the housings feature a large driver which sits in the outer ear and a nozzle that extends into the ear. Interestingly enough, the CKS77 includes what Audio-Technica calls a "2 post" system which allows the user to position the eartips in two different places according to preference. Overall, the earphones seem nicely built with sturdy cables and black plastic housings with a soft touch feel to them around the edges where the housings come into contact with your outer ear.

Comfort: This could possibly be a point of contention for some but I was very pleased with the fit of the CKS77 and it was very comfortable for me over long periods. The driver sat in my outer ear nicely without exerting any unpleasant pressure.

Isolation: These isolate very well for a vented dynamic IEM.

Microphonics: A tad unpleasant at times but nothing excessive.

Sound Quality

Burn in: The CKS77 was given 50+ hours of burn in prior to evaluation and no significant changes were noticed during that time.

They are good and the base is acceptable. one of the reviewers talked about thre symphony in their ear - I think that's going a bit far. While they are better than th average headphones and produce above average base - they are not comparable to a high end headphone. In the 100$ range, they are pretty darn good.

Works fine for me. They are clear as a bell. Had a little trouble getting them for fit the way I wanted, but a little a twist he and there and I got them where I wanted them. They work well on my laptop, my PC, and my IPad. I have no complaints and would highly recommend them.

When I first got these, the bass was almost overwhelming, and did take a little getting used to. I was not used to having that kind of bass in my ear and not feeling it with my body. The mids and highs seemed to be a little subdued, but that has improved with break in. Over the time I have owned these I have compared them with several different sets of ear buds from various manufacturers and have not found anything that sounds nearly as natural and realistic. They beat out a $400 set of Sennheiser professional in ear monitors, which were extremely flat and articulate but taxing to listen to for extended periods. They had better bottom end and smoother top end than Klipsch S4. Anything less than those was not even worth comparing.

They have lasted over a year and a half with almost daily use which is impressive. I added the Comply tips after about 6 months and they became more natural and detailed with tighter more controlled bass and a better overall tonal balance. The only regret I have about these is not getting the version with the microphone for $10 extra.

They do have one caveat that will not affect most people. They have a 14ohm impedance which does not match up well with some sources causing the source to make odd background noises. I tried them with one bluetooth receiver that could not even run them at all because they sent the output stage into oscillation. They cause my Samsung Galaxy Nexus and an inexpensive mp3 player to emit some background digital noise (data seek sounds) though not to the point of making them unusable together. They match up well with my iPod Classic, and don't cause it any issues at all. If this is an issue, the use of a headphone amplifier seems to help.

They are very comfortable but do stick out of the ears far enough that they would not be useable while sleeping. The Comply tips also helped them stay in my ears a little more securely.
