Sonic Defender
Headphoneus Supremus
i think it's pretty good competitor in current market here , of course 240SS got better Clarity and totally black background but i think they are aiming at different target here.
Balanced out provide pretty noticeable improvement imo , especially with darker earphones.
For sure, and as is always mentioned, the price difference with the 240SS is substantial to say the least which I think would lead any reasonable person to feel that the DP-X1 is by far and away the better purchase when performance to value is factored in.
