Package contains : Pioneer SE-MJ503 headphones themselves, warranty card and user’s guide. They cost around 18 Euros : for 10 Hz – 24 kHz and neodymium magnets – this is a great price; there is ability to find cheaper headphones, but their reproducible sounds frequencies range is narrower and they have ferrite magnets; so, these ones – are one of the best variants for high-quality sound playback.
There is also need to note, that for the close price there is ability to buy 40 mm monitor headphones, providing higher quality of basses reproduction. Adding acceptable amount of money, there is ability to buy 50 mm monitor headphones, providing even better basses playback quality and loudness. If from device compactness and small mass are needed, then there is ability to buy in-ears headphones, which do not provide the same quality of audio playback, as monitor ones do, especially in basses area, but they cost much cheaper, have small sizes, are light and comfortably place inside of ears. Which is especially important during sportive exercises and trainings; cable of such headphones often has slider and clip for prevention of tangling and clinging to clothes and surrounding objects.
