Pros
- feels comfy on the ears
- cancels outside noise very well
Cons
- not robust if your looking for a good surround sound quality at high volumes for elongated amounts of time, speakers popped after 4 days of use brought from brand new
- highest volume is actually disapointing
- when using the chord it's seems distorted so do not suggest you buy this Pros

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.

After owning HD 440BT's for a couple of years and loving them i purchased two pairs of HD 450BT's one for my sons birthday and one for me.
My sons set had a large amount of interference so i took them back,
The technician at PB Tech was awesome, tested them and replaced on the spot.
unfortunately the second set was much the same, i figured out after some research it was a firmware issue and was fixed via the Sennheiser app

Disappointed that Sennheiser shipped product like that.

Absolutely its worth for money Absolutely its worth for money

great headphones. Love the quality sound and bluetooth multipoint is amazing great headphones. Love the quality sound and bluetooth multipoint is amazing

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 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.

The only complaint is very quiet white noise but other then that it's great The only complaint is very quiet white noise but other then that it's great

Comfortable and work well Comfortable and work well

Excellent sound quality and very fast shipping Excellent sound quality and very fast shipping

For their price (I got on sale), these are good headphones. I have a smaller sized head so the headphones easily cover my ears completely so is great for passive noise cancelling. Sound quality is good and noise cancelling is average. The battery life is 30hrs so its great to not have to charge them all the time. For their price (I got on sale), these are good headphones.

2nd set of this model we gave bought. (the 1st set still going - these were to replace another make of Bluetooth headphones which weren't as good. Good clean balanced sound, great battery life, easy Bluetooth connection, good range from sound source. Slight hiss in background when there is no music but quite acceptable. Would buy a 3rd set if needed. 2nd set of this model we gave bought. (the 1st set still going - these were to replace another make of Bluetooth headphones which weren't as good.
