    Awesome Budget Headphones

    Great all around headphones. Good job Sennheiser!

    PRO:

    Very good they’re a new model of the 4.30 and they sound awesome I tried them out and I fell in love so I got a pair for myself. They also come with 2 years warranty and also with the sound I heard new words from songs I never heard before. I tried Sony, JBL, AKG, Audio Technica and Bose and Sennheiser has just changed the game when I comes to audio. The sound is flat and there is enough bass for all types of music. Definitely recommend these headphones if not just the Sennheiser brand in general!

    CON:

    Nothing maybe the fact that it’s wired but no big deal.

    BEST USES:

    Travel and home. They also isolate noise very well.

    BOTTOM LINE:

    I would recommend this to a friend.
