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.

Microphone doesn't work with Windows 10. Actually, it doesn't even recognize it as a headphone for me. Microphone doesn't work. I looked for drivers but couldn't find any.
