I bought these headphones about two months ago and I feel in a position to make a review now.1. PackagingThe headphones come in a beautiful fabric case and bring two cables inside - one to connect to your laptop/computer and another one to charge. Some people are displeased that the case doesn't fold, but that doesn't bother me at all.2. Colour and dirt/stainsI bought them in the silver color. One of my concerns was that makeup might transfer over and that they might become dirty over time. This has not happened. When makeup does transfer, you can easily wipe it with a wet cloth. I also tend to wipe the whole headphones every now and then to ensure they don't become dirty over time, especially because if you wear them for a long time, it gets a bit sweaty on the leather bits. The pictures were taken today, and as you can see, they look brand new.3. Noise cancellationThis feature is not perfect. I have not tried other headphones in order to compare; however, when traveling on the London Underground, I can still hear the loud noise that the carriage makes along the tunnels, unless I put the music really loud.4. MicrophoneThis is where they excel. I had Apple AirPods previously, and the microphone was terrible. The Sony XM5 microphone is brilliant. I am told by the people I'm calling that it cancels noise around me pretty well. I use it for casual phone calls and for work as well. It only doesn't seem to work so well if you're sending a WhatsApp voice message - not sure why.5. SoundThis was one of the most important features for me, and it didn't disappoint! You install an app on your phone that will allow you to make some changes to the sound on the Equalizer. I have attached a picture of how I listen to mine. I recommend searching on Reddit for more recommendations on how to play with the Equalizer to listen to music the way you like.One of the first songs I decided to listen to was "Wish You Were Here" by Pink Floyd. Close your eyes, and it's like Roger Waters is singing it right in front of you. My dad was amazed when I gave him the headphones to try with that same song! It's like I can now hear sounds in songs that I couldn't before with my AirPods. But, as I mentioned above, you do need to play with the Equalizer a bit to get to the perfect sound!6. ComfortI find these headphones very comfortable, but it takes a few tries the first time to fit them the way you like. Once you get used to it, you'll be fine. I have worn the headphones for about three hours in a row, and the only thing that starts getting a bit fatigued is the top of your head, but you can always adjust the headphones back or forth to relieve the pressure. The fit is perfect, and they embrace your ears entirely.7. Battery lifeThe battery lasts a really long time; I seldom need to charge the headphones. Just make sure you switch them off when you remove them to put them in the case by clicking the on/off button continuously for a few seconds, as it happened to me not doing that, thinking they would switch off automatically, but they actually stayed on, and the next day there was no battery left. They do charge very quickly, so I just had to charge them for ten minutes to enjoy several hours of music.8. Buttons and systemThese headphones have two buttons on the left side - one that allows you to switch on/off and if you press it once while using it tells you the amount of battery left, and one to activate or deactivate noise cancellation.The right headphone is the one where you can tap with your fingers to play/pause the music; swipe up or down to increase/reduce the volume; swipe left or right for the next/previous song; swipe continuously left or right to move forward or move back on the same song; cover it with the palm of your hand, and it will deactivate noise cancellation while you're covering it (perfect if you just want to listen to the environment around you really quick and then get back to your music).The headphones are a bit sensitive, though, and sometimes when I'm just fixing their position on my head, I accidentally touch the right headphone and end up moving to the next song or to the beginning of the one I was listening to, which is annoying. I am still getting used to this system.9. Overall opinionI would give these headphones a 9 out of 10. They're not perfect, but they're pretty close to it, in my opinion. These are headphones that I intend to keep for years to come. I think they offer a good price/quality ratio, and from the reviews I read before buying these, they are superior to many other popular brands.I did consider buying the XM4, but the reviews stated the microphones were not as good. If you intend to use the headphones for phone calls, video calls, work, etc., I believe the XM5 are the best choice.
