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

These are an awesome set of headphones, particularly for the price. Easy to use, and I like the separation of the pause/play and volume buttons, making it easier and faster to make changes while listening. Definitely a fit for someone with smaller ears, and they do take a while to soften up (feeling quite a squeeze!). Love the super long battery life as well, and they come with a nice little carry case. The only thing that would get these 5 stars would be higher comfort out of the box.

Really glad I got these headphones. Sound is great, they're comfortable, I've had them for a month and use them every day and I haven't had to recharge yet.
It did take a week to work out how to push the cable in and rotate it when plugging in but the sound is perfect once the cable is in correctly. Really glad I got these headphones.

It is a great product for its price. The sound is really good. You get decent volume, plenty of bass and a good amount of clarity. The battery lasts for ages and the fit is comfortable. Noise cancelling is not bad either.

Sound works well also using the chord. You just need to rotate the 2.5mm jack to lock it. It is a great product for its price. The sound is really good.

Only real issue with this headset is that the muffs are way too small and until they softened up chaffed my ears quite a lot. If you have smaller ears though, this is money well spent. What you get for the price is actually really good value. Only real issue with this headset is that the muffs are way too small and until they softened up chaffed my ears quite a lot.

I wish someone told me this before. I spent days researching headphones with APTX low latency thinking I would have the dream of quick response headphones. Once I connected these to my computer I quickly learned it doesn't work because computers/laptops and most phones don't have it. The only way to use this would be to buy a third party Bluetooth adaptor/dongle to plug this into your computer so both devices have it. Nowhere was this ever written specified when I researched these headphones this was the case and only found out when I researched why it wasn't working when I tried.

That aside, headphones are ok. I would say only worth it remotely of you get them on sale, don't pay the full price for what you get here.
The noise cancelling works but isn't that strong. I have had to do a lot of fiddling around with connecting these to computers via Bluetooth but I think that's on the computer not the headphones as they connect to phone easily.
The head band is ok in comfort but is quite firm and not the most comfortable overall.
The sound quality is good but there is static if you are listening to audio through Bluetooth which is noticeable if you are listening to talking, not so much with music. The static is louder if you have the noise cancelling on as well.

These headphones are awful.
The noise cancellation is non existent after 6 months.

You will be routinely shouted at by robotic prompts at various stages of their use. Forget about trying to use noise cancellation without playing any kind of music (when it was working). Don't think you'll be able to fall asleep with them on either at home or when travelling because the moment they hit a certain battery threshold - you will be shouted at by more robotic voices and abruptly awoken from your slumber.

The smart control is not compatible with these headphones and they have deleted the old app.

The smart control is not compatible with these headphones and they have deleted the old app.
The arms will chip off from the side of the ear cup after a few months with normal use (as seen on a co workers pair as well).

The battery life and sound quality are OK but the blue tooth drops out a lot (unless my other headphones) and the pairing routinely pairs to the call functions only and so you have to constantly reboot the phones in order to pair with stereo if you want to listen to music.

Without a doubt these a the single most annoying piece of kit I've ever bought. I really can't understand why the designers thought it would be a great idea to have a shouting bot nagging you at every stage of the phones battery life. The world does not end if the battery depletes - just let it run flat - we can work it out.

Awful quality headphones, doesn't worth to buy even on sale.

Pros:
- decent sound quality

Cons:
- constant white noise when noise cancellation is on
- noise cancellation does nothing (the only thing you can distinguish if it's ON - white noise in background)
- controls are so small and messy that it's hard to use them
- ear pads too small and tight, that you have actually squees you head through. I guess they made it on purpose to improve passive noise cancellation, but as a result after 5 mins of use ears start sweat and you feel you head squashed
- to understand assembly quality - I found some glue drops on mines

Overall, if you think that Sennheiser couldn't be so bad - this the case. Don't waste you money!

A few key issues with this product.
I use it for online meetings.
People complain about mic sound quality.
Sometimes it disconnect unmotivated during a meeting....
Noise cancellation works but not impressive. Doesnt stack up to Bose.
Might be fine if you use it for listning to music. A few key issues with this product.

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.
