Pros
Pro Good sound quality with nice, full bass and lively highs
The low end is powerful and punchy, adding a lot of thump to the music. Explosions from movies and games really stand out. Hip hop and EDM genres will also work well with these headphones.
Highs are forward, so audio details can easily be appreciated.
The mids on the other hand are recessed, which results in a V-shaped sound that many consider to be fun-sounding.
Pro Wide sound stage
The semi-open design results in a wide and natural sound stage. Combined with the great sound imaging, these headphones can give an immersive audio listening experience.
Pro Soft and comfortable on the head
The ear pads and headband are cushioned with thick foam which can help give a comfortable listening experience.
Pro Cable can easily be changed
Connected to the left ear cup is a 3.5mm breakaway male jack, where you can attach a 3.5mm female to male cable. Changing and replacing cables should be easy because of this feature.
Pro Comes with two headphone cables
It comes with a 1-meter cable and a 3-meter cable out of the box. Not only does this give you the option as to the the cable length that suits your needs, but you also have a spare cable available in case one gets damaged.
Pro Exceptional mic
The microphone has good clarity and can actually be used for tasks other than talking on the phone - like recording podcasts on the go for example.
Pro Comes with two different cords
One cord comes with an inline mic and with controls, and the other cord is your standard audio cable. This inclusion not only allows you to pick a cable to best suit your use-case for the headphone, but this also ensures that you have a spare cable should one get damaged.
Pro Good bass reproduction, warm mids and smooth highs
The bass of these headphones is pretty good. Bass drum hits have good power to them, yet they do not muddy up the sound. The mids are warm and forward, and should present vocals and mid-range sounds quite well. The highs do not have a lot of sparkle, but they are clear and present a good level of detail.
Pro Can effectively cancel out noise
With these headphones it will be much easier for you to focus on your music, or whatever it is that you are listening to. Combined with the closed back design, airplane/train/bus engine noises are effectively cancelled out.
Pro A good number of accessories are included
Along with the two headphone cables, you get a carrying case, an airline adapter and a 6.3mm plug. These should help make the headphones easier to transport and also make them compatible with a wider range of audio sources.
Cons
Con Clamping force can be a bit too tight
While this is somehow mitigated by the thick foam on the ear pads, users who are sensitive to clamping pressure will very likely find these to be a little too firm.
Con Highs can be harsh
The highs are clear and forward, but at times can also be too much. The sound can get fatiguing to listen to, especially if the user is sensitive to treble.
Con Feels flimsy
The 668B's build is primarily made of plastic, and the fit and finish is not that great. You will hear and feel a lot of rattling and the plastic will flex often. These are budget headphones and it shows in the build quality.
Con Heat can build up quickly around the ears
The vinyl material that covers the ear pads may feel soft and comfortable on the skin, but it also traps heat pretty well. Heat can build-up quickly around the ears, which can be uncomfortable for most.
Con Requires an amp for optimal volume/sound quality
If you really want to get the best sound quality as well as volume from these headphones then you will need a decent headphone amp. The impedance of these headphones is quite high at 300 Ohms, so these require a good bit of power to function optimally.
Con Can get uncomfortable for people with larger ears
The ear cups of these headphones are quite compact, and may rub against the ears of some users, which can get quite uncomfortable.
