when I purchase the cv123 combo pack -lrb- which buy the way be not even close to worth buying -rrb- , these headphone be part of the pack . as for as sound go , it be average . it be pretty flat , no really big bass or good treble , but it be not terrible . they be also very comfortable , and be not too big . the durability be pretty poor , however . they do not last very long so buy two or three . but for barely above a dollar , these be a definite buy . if they be more expensive then say five dollar , then I would go for some sony .
