I wonder how long the hunger for headphones will last? Looking at the rapid development of this segment of the audio market from a consumer's perspective we can only enjoy it. Competition is increasing and manufacturers have to to really try if they want to get the attention of a potential customer. We must admit that headphones are a convenient solution for people who want to enjoy music at the highest level, but don't have the conditions for a classic home set. Or they demand mobility, which is very likely due to the parallel development of portable DAP players. Price is yet another factor. Headphones and dedicated amplifier costs a few thousand euros, but it can give better sound performance than a set of speakers and classic amplifier at the same price.
