Recently i got a Altec Lansing AHP-512 headphone in my lab. It came as a giveaway with my father's speaker Altec Lansing VS2121. In short, it has all the disadvantages of low level altec lansing headphones such as too much bass and very very uncomfotable. I can't wear this for more than an hour. Except for those, it's sound quality is OK for a low level headphone, though i don't know how much it costs,i can't find anywhere to buy it in Taiwan. It has a long line, plus an in-line volume control. It's noise concealment is good, which just fits my use in lab.
In all, if you like heavy bass and can bear the uncomfortable, this is good choise for you ; otherwise, leave it away, it doesn't worth your money.
