I got a pair of lenntek sonix (black) about a month ago. I wouldnt say im an audiophile but ive recently started to appreciate high quality audio, so i may be a little inexperienced.
I thought you guys might want my opinion.
I got mine for about $20 - great deal from costco
I would say that right out of the box they have quite overpowering bass and mids, but the detail is still there (although drowned out somewhat). They sound like your in a different room. But after some burn in time, the bass evened out nicely. I would still say that they are still a little bass heavy, but the bass is really nice, punchy, high quality, and definitely not muddy. If you tend to prefer mids and lows, but still like a balance, these are definately for you. After improving the treble with EQ, they sounded even much better, and I have to say that the detail is definitely there, and even though the highs could still be improved - they sound really great. Im just being picky about the highs. The mids are just fine and nice and warm. The only time I would hesitate with buying these is if you listen to music that is predominantly treble and high notes. But for most music these are great. and for the price id get them anyways.
and the sound isolation is also very good
The build quality is great, not cheap like the price suggests. they are the first phones that i have not had tangle problems with (the nylon cord is great) they are scratch resistant, and ive heard stories of people swimming with these in their pocket, and they still work... so durability isnt an issue.
Now I dont have years of experience, so I cant really compare them with past headphones ive had (I used to listen to stock ibuds
(). But I did listen to uncompressed files on my ipod and I compared the lennteks to a quite high end stereo system - although its sometimes hard.
I am very happy with mine and I would have been willing to pay a lot more for these.
