I'll say this, if you buy cheap Sony products they will preform like cheap Sony products.
I've had a lot of Sony computers and they have outlasted many Dell or Acer computers.
Sony cans are pretty kick ass. Ever heard of an MDR-7506 or MDR-V6? Some of the most popular, durable, and great sounding mixing/road/music cans out there and I've tried a lot of cans. I've had a **** load of earbuds too and I love my Sony MDR-EX90LP. I usually go through earbuds yearly but I've had these for almost 2 years.
Their TVs are very high quality, unless you buy the **** low line ones. The ES line of HT equipment is very high quality as well.
Oh and ever hear of the PS3? Or Blue-Ray?
Why don't they make good car audio gear anymore? No room for quality in a quantity market. Basically, most of the market is filled with pimpled faced 16 year old teens who know nothing about anything.
