Closed vs Open Headphones (DT 770 vs DT 990) Closed cans like the 770s isolate the listener from the environment, meaning little noise gets in or out of the ear cups. Thatβs great for recording where you want to minimize bleed into the microphone, as well as for public use or quiet nighttime monitoring.
The 990s are excellent for normal studio use when you want to hear everything clearly, since the 770s have low output on mids and highs. I own all three and they all have their uses, but the v modas work the best for djing. Pay close attention to ohms. The v modas are efficient enough to be driven by dj controllers, but the 770 and 990 are not.99dB/mW. 96dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source. has a neodymium magnet. Audio-Technica ATH-M50. Beyerdynamic DT 990 Pro. Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets.
