Kinivo BTH240 PRO Wireless Bluetooth Headphones - Over-Ear HiFi Stereo Sound, 30H Battery Life, Built-in Mic, Foldable Design for Travel, Hands-Free Calls | Perfect for Commuting, Workouts & Office Use

First and foremost, these are the very first bluetooth headphones that I have ever bought myself, let alone ones that go behind your head instead of over the head. I had bought these headphones based on the positive reviews that I had found on Amazon as well as the positive reviews on YouTube. The price appeared to be just about unbeatable for the value you would receive from these headphones.Let me first talk about the positives for these headphones.I am a young man that loves to style my hair with products and thus I have been looking for earphones that would not ruin my hairstyle. These headphones do exactly this.They wrap around the back of the head without ruining my hairstyle and the products in it. Next, the sound quality of the headphones are actually very well for the price you pay for these. I actually began to find some new instruments in my music due to the impressive quality of the sound coming from these headphones. To reiterate this, they are impressive due to the fact that I was not expecting much quality judging from the price of these headphones. The buttons work splendid and are very useful, they allow me to listen to music with my phone in my bag instead of in my pocket which helps a lot especially when you have a fat bulky phone. The way these "hook" onto your ear is very well done and the headphones do not come off easily from daily use. An example of a perfect-use for these would be in the house when you are cooking or if you were eating in the kitchen late at night as you do not have to blast music to disturb other family members. The battery life is also extremely outstanding for the price you pay for. I've literally used these for two weeks without charging it once. These are fantastic.Now let's get a little critical.As I had mentioned above, these are fantastic headphones. However, I had bought these headphones with the intention of using it for the gym. For all of you planning to use these headphones for weightlifting, please read this next section carefully. Firstly, the product may get in the way when laying down on a bench. You most likely have to tilt the back of the headphones downwards towards the neck to avoid resting your head on the headphones when laying down. Next, I workout in a very loud gym. For the noise-cancelling ability of these headphones, you get what you pay for. It is not nearly as good as brand headphones. So keep that in mind if you go to a very loud gym. Now, in addition to that, although the sound quality is crisp, the maximum volume of the headphones is not as high as I need it to be for the gym. Mid-volumed headphones combined with minimal noise-cancelling makes these headphone unideal for a loud gym. Lastly, for the durability of these headphones, you also get what you pay for. They will break easily if uncared for. They are not sweat-proof so if you are a sweaty athlete, expect to be wiping these down a lot. To add on to this, if your gym does not contain adequate AC, expect these headphones to increase the amount of sweat that you will be producing. I am not saying that the headphones heat up; instead they do not provide ventilation for your ears to breathe.I am still giving these headphones a 5-star rating, why? The company does not advertise or promote these headphones for physical activity. It would be wrong for me to give poor ratings for using these headphones for a purpose of my own that did not go well. I am very well-aware that the headphones perform exactly as advertised. I have put these headphones through an extended test of my own in the gym and although the results were unfavourable, the headphones still performed as mentioned. With the right adjustments in my purpose of using these headphones, all is well. Well done Kinivo. Five stars for you.
