AKG Small Studio Headphones thorough comparison of 3 types !

The "K171 MKII" sounds like the best studio monitor headphone among the three models compared this time. The sound is flat with no extra flavoring. It faithfully reproduces the sound source. The bass range is modest and solid, but with the high resolution and clarity of the low end and the sharp mid range are quite good, and the subtle touch of the jazz drum brush work to the sound of the strings of the wood bass are reproduced vividly.
The sense of fit is strong, so if you want to emphasize a firm fit and good sound insulation, the "K171 MKII" is perfect.

If you want to use headphones for easy listening as well as for monitoring, we recommend the "K141 MKII" as the most easy-to-listen and expressive sound.
Among the three models, the bass range is the thickest. The sense of clarity of the sound that seems to be common with semi-open types adds a spread to the bass region moderately, and the middle high region is a soft sound with sharp corners. Live instruments such as violins and acoustic guitars produce a glossy expression and a sense of air. "K171 MKII" is one good at delicacy & flatness of sound, but the "K141 MKII" slightly wins out in the ease of listening to music? That is the impression I got.

The entry model of the AKG Studio series is the "K121 Studio". This is a good thing.
The sound character is in between the "K171 MKII" and the "K141 MKII", and the overall balance is good and it sounds evenly from high range to low range. There is no noise in the sound, and it is good for both monitoring and listening. Because it is s semi-open type, there is also a wide sense of presence, and the sound is easy to listen to. The low range has a rather conservative impression compared to the "K141 MKII". The cable is not detachable, but it is a headphone that boasts high cost performance, though it does have a slightly overstrong pressure on the ears.
