Sennheiser HD 450BT Wireless Over-Ear Noise Cancelling Headphones - Black

These headphones well exceed their value for money. Comfort is A+ for long term wearing. Sound cancelling and sound quality are both excellent. Battery life A+. First time user of Sennheiser and very impressed!!! Qualify this as a must buy if you want excellent quality but are on a budget. These headphones well exceed their value for money.

These are a great at-home option but actually perfect for sports, running, gym, etc. They don't budge once fitted and the build quality is solid without being too soft/sensitive like the Bose and others.

I purchased a set of these in January to use on a flight to the UK. They worked fine for that trip, but after about 8 months they have failed. First the battery stopped holding charge, so each time I went to use them they were flat (even after 48 hours, and I had checked the battery state via the app). Now they turn on and make a whining noise; the only way to power off is to reconnect the power cable. Attempting to connect via BT or the app fails every time.

They are going back for replacement (NB, I didn't buy these at PB tech, but at a well know store HN - we don't have a PB Tech in my city).

Similar to other Sennheiser products the sound quality is good, but they are unlikely to last long. Battery starts failing to hold charge after the first few charges. First charge lasted around 30 hours however after a few weeks this was down to around 9 hours which was still acceptable but soon after even if it was fully charged, if not used in a few days the battery would be empty Similar to other Sennheiser products the sound quality is good, but they are unlikely to last long.

Nice and light. Can get totaly emerged in the music without external interruptions. Worth every penny. Comes with own bag. Nice and light. Can get totaly emerged in the music without external interruptions. Worth every penny. Comes with own bag.

These headphones have delivered brilliant audio quality that have elevated the commute time to somewhere near pleasant, and despite all the negative reviews on comfort, I found them to be fine. Overall would highly recommend.

Sounded trash out of the box, both through bluetooth and aux. After disabling "use for calls" in android settings and breaking them in for a while, they now sound ok, but not super balanced. The mids don't feel very full or rich. Not as good as the plantronics backbeat pro 2 for example Sounded trash out of the box, both through bluetooth and aux.

Good earphones (this is a second pair for another household member). Effective noise cancelling and the instructions on how to use are clear. Sit comfortably over the ear. The case is a bit disappointing just a material bag. Good earphones (this is a second pair for another household member). Effective noise cancelling and the instructions on how to use are clear.

The noise canceling is not working I believe. Or Maybe not a good quality. The battery works fine. I did want sth with good sound quality so this headphone is working fine for me The noise canceling is not working I believe. Or Maybe not a good quality. The battery works fine.

I purchasedVery good headphones for what I paid. Bluetooth functionality is quick. Very good noise cancelling tech. Decent trebble and bass mix, not too heavy.
