I'm a big fan of wireless bluetooth headphone. I own Bose QC35 (which is one of the best in the market now) and Sennheiser 4.50 BTNC is my second headphone. To all audiophiles, Sennheiser no longer need introduction. So, what is so great about this headphone?
Design of 4.50 is simple, light weight (as light as QC35) but very plastic feel. Therefore it's very easy to smudged with finger prints even though the surface is not glossy. However it doesn't impact on the sound quality. The sound quality is equal or even better than QC35. As for noise cancelling QC35 is still best in class. Do take note that not many people like the QC35 noise cancelling effect. Too strong of noise cancelling can cause uncomfortable to some consumer.
Even though noise cancelling is not as powerful as QC35 but it would not give you any uncomfortable feeling or I would say vacuum feeling. 4.50 offer a balance of everything. It give above average noise cancelling, comfort, good audio quality, compact folding design and most importantly with an affordable price. It cost USD199.95 retail price which is far cheaper than other competitors.
It do come with a soft pouch. Not any of those hard case type but it's good enough to protect it from any scratches. When you dump in your bag, it won't eat up a lot of space.
Finally, what do I think of Sennheiser 4.50 BTNC? Personally I would RECOMMEND to anyone who is tight on budget but still would like to enjoy a pair of quality headphones. Do not expect many features on 4.50 as it's very simple and user friendly (QC35 doesn't offer many features as well, why worry?). The only problem that I observe on 4.50 is for those who got bigger head. After more than 2 hours wearing it your ears will feel uncomfortable. Over the time I believe it will accustomed to your head after frequent usage.
