So my reviews.
Technics RP-F600. I have been using for 1.5 years. The source is the sound card Asus Xonar D1.
In 1x, from the pros - very comfortable fit. Headphones are light, and surpassed perfectly, you can sit for hours. The only thing - kozhzam ambushures tend to sweat.
Headphones half-closed design, not very isolated from external sounds.
The quality of sound claims a little, you can only complain about the early fall of the RF. The bass is deep enough, but at the same time rather smooth, not “protruding”.
Operational flaws - the cover (or more precisely, the two teeth that held the cover) of the adjustment mechanism of one headphone broke. Disassembled, put the spring in place - it all worked. I wrap the cover with tape :)
Koss Porta Pro. Legendary headphones.
To begin with, they sit perfectly on the ears. Adjusting the clamping force is a wonderful thing! Headphones can be twisted into a small tangle, to save space :)
Design in retro style - an amateur.
Metal arc has unpleasant features. In 1x - she somehow manages to pull the hair, unpleasant.
In 2x - the bow in the frost is very freezing, and in the heat, on the contrary - it is heating up, so when you hang headphones on your neck it is unpleasant.
Many yuzorov foam often breaks / breaks. I did not have this.
Soundproofing, due to the open construction - no. With the sound of the problem. A strong bias in the direction of the woofer, moreover, the bass is strongly protruding and "smeared". HF and MF are simply drowned out, listening to the ports of the pro without equalizer correction is very hard.
In addition, I had two pairs of these headphones. The second pair of bass was even more hollow and smeared.
Sennheiser CX300. Disappointment. Landing in the ears - disgusting, for a long time I can not wear these headphones - my ears start to hurt. Wire, however, good quality.
Sound insulation is average. The sound is disgusting. Little bass (I'll sleep on the landing). HF, as they say, cuts ears.
Headphones suddenly died after 1.5 months of operation. Just one earpiece died, after which they were thrown into the drawer without regret and forgotten.
Fischer Audio Enigma. Ltd! For its price is an interesting option!
Headphones are small, sit perfectly, like a glove, and are not felt in the ears. At all. Yes, and good insulation.
The sound for the gags is amazing! They play widely, with a soul :) The bass is very deep, slightly protruding, but it plays "as it should." The voice and guitars are pushed slightly to the fore. On HF, the blockage does begin quite early, the plates do not have enough ringing.
And then - the cons. The main one is wire quality. He is thin. Very thin. From contact with the skin of most users, it dubeet and breaks only after several months of use, often at the point of entry of the wire into the earpiece. The nozzles are comfortable, but they are not very comfortable in the sound guide, and after a couple of months when you pull out the headset, you can find that the attachment is left in the ear. I was extremely unpleasantly surprised by this fact.
But the plug seems to be just an armor piercing :).
The verdict is headphones for those who can re-solder the wire and deal with the tips.
AKG K420 Denim. To begin with, the headphones fit well in the ears. Ears begin to get tired only after 2 hours of continuous wear.
Headphones are quite bulky. But they have IMHO design - interesting.
The sound is balanced and with wide stereo panorama. Deep bass, treble does not cut the ear, everything is fine :)
The disadvantage is that the plug is straight and flimsy in appearance.
The source for all portables is the Sony NWZ-A728.
The plans - a change of technics for Audio-Technica ATH-M50, and phishers - for fittings Philips 9850 entry level.
