Half the job
I was disappointed on 2 counts: 1) I bought them in a hurry so my wife, dying of cancer and subjected to horrendous noise from building alterations could get some peace. They do block pot much of the lower frequencies, but the constant chitter-chatter from builders with their foul language just comes straight through! So they are quite ineffective for the purpose. 2)music was not a primary purpose, nevertheless, the picture presentation with blue light and no cord pictured led me, in my hurry, to think I was buying Bluetooth, but no, they are corded. The presentation was misleading.
