Hi, badly need advice from you wise ones out there. I am a professional novelist and arty type. Here is what I need. A pair of over ear headphones. My case unusual. I need these to cancel out neighbour noise that drives me nuts and is now interfering with day job as I have to work from home. They need to cancel out music and radio, mumbling background TV and barking dog. The noise is loud enough to prevent my work but nothing can be done so I have to soldier on. The headphones should cancel as much noise as poss, be comfortable for long stretch. If I could use the noise cancel without music that would be fab. I don't always want the music on. If I do, for writing it is low, so I need excellent background noise cancellation. Help, I am confused by advice from merchants, need unbiased help. Price does not figure although lower the better. I will pay for these but they must do the job with at least 90% background cancellation. I cannot wear in ear or earplugs due now to severe allergy from trying to block this noise out. Any guidance would be great, I am a novice at this. Thanks so much!
