Bowers & Wilkins hits the market with its latest headphone design in the form of the PX. This is the first set up ever from this manufacture that offers bluetooth active noise cancellation(ANC) with an added "Smart Feature" that is able to detect when your headphones are removed in order to pause audio playback. So lets dive in hopefully this review can be helpful in deciding rather or not this set up is going to be the right fit for you. First off lets talk a little bit about B&W and what you can expect to receive out of the box. If you have never heard of B&W (Bowers & Wilkins) its probably because they are a British made company that is very well established and popular over seas. They take a lot of pride in the products they make and it definitely shows in the PX wireless. Out of the box your going to receive the headphones, instruction booklet, USB-C charging cable, 3.5mm cable and a carry case. The first thing i noticed right off the bat was how elegant the carry case looked. I felt almost as if i had been given a Louis Vuitton bag, the quality was that nice. Your going to get about 22 hours of claimed battery life. So far i've managed to get about 20 hours of life with my settings set at a modest level. Full charge can be received in about an hour all via the USB C cable. One thing i want to mention is this is the first headset i have ever come across that utilizes a USB C cable and i have a love hate relationship with this fact. The main reason being that almost every cable in my house uses a micro usb cable. What this means is i can leave my cables throughout my house and basically all my devices share the same cable so there is no need to go searching for cables when my power gets low. With this headset set up i now have to carry the USB C cable with me where ever i go, now making him the odd man out. Now if your not too familiar with this cable set up the USB C cable is found in alot of laptop and google products. With out being too technical it basically allows for more added features with one of them being quicker recharge times. Its basically going to be the new design of the future so i guess im just going to have to get used to it. B&W also provides an app that allows you some key features such as noise cancellation control and firmware updates. While i cant speak for apple users i can say that pairing the headphones to the app and my android phone is done very quickly and all within a matter of seconds. Now in most situations i really don't feel a need to have an app for an audio device however with this device i feel its kind of necessary. Lets talk about the app for a minute. The app allows you to manage and control your ANC volume. You are also equipped with three different noise cancellation features. They are office, city, and flight. Office is modest and allows more noise to enter the headphones where as flight mode is pushed to the extreme offering maximum noise cancellation. The headphones also come equipped with sensors that detect when your headphones are removed and will stop playback until you put your headphones back on. The app allows for you to also be able to control the sensitivity level of these sensors. Through the app your also given the ability to update the headphones firmware and this right here may be the single most important reason for the app. Right out of the box the headphones needed a firmware update and were two versions behind. The updates took about 30mins so just be prepared to wait. The layout of the headphones are done very nicely as well. The right headphone houses everything including 3.5mm jack, charging port, power button, ANC button, volume up and down button and action button. The action button allows you to pause and skip tracks and also answer phone calls. It is real easy to find because what B&W did was protrude that button slightly to stick out more making it easier to find so that you do not get it confused with your volume up/down buttons. If your don't feel like messing with your noise cancellation features there is a button you can press that will automatically turn on and off noise cancellation. A really interesting design that i found was that the cushion ear covers are held on magnetically and can be replaced with ease if they were to ever rip or get worn down. I have not been able to find a price yet as to what they may cost however i have provided a picture to show what they look like when they are removed. Lets talk audio quality and features. First off i wanna say the audio quality is awesome if not some of the best sounding headsets out there. Which is good because the noise canceling feature side of this is very weak. I own quite a few different audio devices that provide ANC and this headset is by far the weakest. Its not to say that it doesn't block out outside noise its just to say that certain noises still gets through. If you are thinking of buying this headset primarily for the ANC feature i would say to pass because there a lot of other audio devices out there at this price point that do a way better job. However if your looking for a good audio headset with ANC being a side feature then i would definitely say step right on in. This audio is so crisp and clean it gives you a feeling of actually being in a studio or concert hall. All the sounds are so crisp and clean and can be heard clearly without delay or lag. One thing to keep in mind is when quality is this good you are going to start to notice how good or bad audio tracks were produced. Meaning as i listened to Disturbed's "innocence" I could hear the vocals so clean there was no need to figure out what the lyrics were. The cymbals and drum bass came out so clean that i felt almost as if i was listening to them live at a concert. Now as i listened to Swizz Beats "Top Down" i noticed a big difference in audio quality. I know these are two different genres of music but the audio quality seemed more withheld, it was as if i was trying to make out if that was a bass drum in the background or a snare. Also it seemed as if the bass was just lacking all together. Just know that audio tracks are gonna sound different at this level of quality depending on the artist and their set up. Also another thing to note for all you big bass lovers out there is this audio is not very big on the bass. Its not to say you don't hear it or feel it but it just means that if your looking for something to punch through and rattle your bones then you may want to pass on this. Understand there will also be some audio quality draw back too if you decide to turn on the ANC feature as well. Now the feature that really got me hooked was the pause/play feature that is enabled whenever you take off your headphones. This feature is the first design i have personally ever seen that is able to detect when you are actively listening to the music or not. So lets say that you are listening to your favorite song and you lift just one ear bud up to listening to what someone is saying. The headphones will pick up on that and pause your music. Once you pull the earbud back down it will resume play from where the song was paused. Now how about if someones at the door and you take your headphones off and set them down? Well as soon as you take them off or set them around your neck they stop playing immediately. If you don't put them back on after about a minute they will go in to a power down rest mode preserving battery life. Now the cool thing is after you put your headphones back on there is no need to power them back up. They power themselves back up and you can hear that through the headphones. Once they power back up they will resume playback from the exact same spot you last heard on your audio track. Now as far as comfort goes this headset is ok. After about 3 hours of straight use the top of my head started to feel the pressure points. I think alot of this is due to the rigid aluminum design with minimal cushion support for the top of your head. If they had added more cushion then i think this may not of been an issue. Not a major drawback but just something to note. Another feature i wish they would of implemented would of been a fold away design for this headset. The headphones do not fold inward so when it comes time to store them in your carrying case they need to be retracted and folded flat. Here are my final thoughts. The audio quality can not be denied and the smart technology that detects when you have the headset on is a really cool feature that almost makes this a must have. With 22 hours of battery life and a 3.5mm jack and usb c cable this makes it a good competitor right out of the box. However if you tend to do a lot of traveling and are looking for something to block out as much noise as possible then i would have to recommend that you pass on this headset. While the audio quality is superb in every single way the ANC feature is average at best. This headset is designed around getting true in studio sound just the way the artist intended it to be heard and that is why i gave it five stars. Though noise cancellation may be lacking the audio quality does more then make up for it. When buying this headset understand one thing. There is a burn in time or break in period. Most headphones have to go through a few hours of playtime before the true quality is felt. Pros: -Good battery life -Fast charge time -Superb audio quality -Built in recognition for pause/playback -Ability to update firmware Cons: -Lack of a fold away design -Weak ANC
