Sennheiser HD 450BT Wireless Headphones with active noice cancellation, black

Bought these as a gift for my dad. He informs me that the sound is excellent and the noise cancellation is just as good as his old Sony's, if not slightly better. Battery life is excellent, lasting hours into the night.Full price or discounted these Sennheisers are worth the cost.

I bought these nearly two years ago now. They still work perfectly, the battery still lasts over 12 hours with daily use - they have gone on holiday with me, I have fallen asleep with them on etc etc. Very good purchase. The sound quality is fantastic, excellent spatial sounds in games and music sounds wonderful. The bluetooth range is a lot longer than I thought it would be. My only slight complaint is that the material that lines the headphones has come away revealing the sponge underneath, I am sure I could send them back as the warranty was for two years, and get them repaired, but I will just stitch it up myself. But honestly not an issue at all, I am pretty rough with these and have a toddler who likes to pull them around a touch!!I would recommend this for anyone who wears headphones for a long time, they are very comfy. I believe I will still get another 2-3 years out of them minimum as they show no signs of any weakness etc.

Overall sound quality is good and better than average. Bass response is good, mid to high range is OK and the look and feel is general better than average. The ear pad openings are not as big as some, but fitted my ears perfectly and they can be worn for extended periods. If you plan on moving around or even dancing with these, the plastic housing can make creaking noises but sitting still they are fine. If you like classic rock and the volume turned up like I do, then this should not be a problem. Bluetooth stays connected to you device but the buttons are fiddley and take a little getting use to. The phone app could be better and give more options to adjust sound quality. I do think they are over priced at around £80 and think they should be in the £40 to £50 price range. I don't use them a lot, so will have to see if they stand the test of time.

I had these for several weeks before I gave this to my sister and upgraded to B & W PX7.They come with a cloth carrying case but I recommend buying a hard case for these.They are built really well and no creaks or sounds when you use them.I like the looks of these headphones. They're very subtle and don't look "In your face". If you like that sort of thing you will like these.Sound Quality is quite good. Good bass, Good vocals and everything. Also these are very comfortable and lightweight. Ear cups are not the best will cause a little bit of sweating but it's nothing major.Noise cancellation is also decent for the price. Controlled by a button in the headphones but there is not confirmation of it turning on or off. You have to rely on your ears to figure out if the NC is on or off.Battery life is excellent. You can easily go one week without having to charge these.You can connect this to 2 devices at a time. You pause music in one device and play on the other these will switch over. Also if you receive a call on your phone while you're using this on your laptop, These will switch automatically to the phone call.Now to the things I don't like , My minor gripes about these are that they don't pause automatically when they are taken off from your ears (PX7s do). Also they do not go into standby or shut down when not in use (Again PX7s have this). But for the price I think it's acceptable.Also volume is not that loud. you need to have these around 80% volume to be loud enough (My testing device is an iPhone 11 Pro Max) (My PX7s are much louder and bass heavy than this but they cost more than twice)Overall I think it's a great pair of headphones you can buy for this price. I cannot think of anything better unless you want to exceed the 200 pound mark.

This is the second time I have bought headphones from Sennheiser and while I was very happy with the product the first time, the second time the headphones had manufacturing defects. When turned on and connected to any of my devices via Bluetooth, they emit a squeaking sound if no music is playing. Additionally, the headphones sometimes turn off despite still having battery life (this has happened even after fully charging them, and the Smart Control app itself indicates that they still have charge). Unfortunately, I have been trying to contact the company for the past few months to try and make claim the warranty through many email and phone, but haven't succeded in reaching them. I had read in the past comments of other people complaining about how hard it is to get in touch with Sennheiser for warranty claim purposes, and now I sadly realise this is indeed true. It's such a shame, since I really used to like this company's product before.

The sound quality as well as the noise cancellation system of the headphones are crazy awesome. It has good bass quality. Charging was quick. Lightweight. Sleek, minimalistic and elegant design. Can connect devices 10 metres far with its BT 5.0. In total, worth it.

Odd headset. Connect to both last 2 paired devices automatically, no way to stop this. Really annoying when one goes out of reach and you get constant 'connection lost' messages. Sound quality good though.
