Sennheiser HD 4.50 SE Wireless Bluetooth Noise Cancelling Over-Ear Headphones - Black | Premium Sound for Travel, Work & Music Listening

Pros:CostFunctional noise cancellingGood sound profileBluetooth connectivity is strong (I had a pair of ATX that lost connection if they were in the wrong pocket, these are good across my whole house)Cons:Noise cancelling can be easily overwhelmed compared to more premium headphonesNot as easy to forget you are wearing as the open back 598s that made me love SennheisserMay leave you wishing you had spent 2x as much for the step up to Sony MX-1000, Sennheisser Momentum, or Bose Quiet Comfort 35I will start by saying that I am a Sennheiser fan, and that I own many of their products, including the venerable HD 598s and several other premium open back headphones. I wanted something that I could take with me without having to worry about cords or that sound was leaking to those around me, and these seemed like a good choice. I already had a pair of over the ear Bose headphones that kind of filled that spot, but they weren't noise cancelling and I wanted something that was a little better for leaning back and relaxing on airplanes. Are these good for that? Yes. But they are considerably larger, and the two have very different sound profiles. Instead of putting the Bose aside or gifting them to a young cousin as I thought I would, I find myself trading off between the two. When I go out and about I take the Bose, because they are very compact and comfortable, and unlikely to interfere with headrests; they also allow me to retain a good deal of situational awareness as they don't interfere with peripheral vision and are only marginally sound dampening. When I'm around the house and want a little peace and quiet from the family I use the Sennheisers, and I also bring them anytime I will be staying in a hotel. Even though the noise cancelling isn't perfect, most of the time I would rather have it than not. It performs very strongly to cancel out the sound of fans and other constant droning noise you didn't notice was in your house until you have used noise cancelling and then turned it off again.Also, in a totally unfair head to head, these don't really stack up against the Sony MX-1000 that I got my dad for his birthday.
