-> Sound:
From the sound I was very pleasantly surprised! The highs and mids have a good balance and not about control. As it is with bass, I can not say. I can not hear bass heavy music, but guess that you should not expect miracles here. Any music that I've heard about the BackBeack Fit, sounded really good for kudos!
The headphones are built more open and thus protect not completely. Means that one ambient noise still perceives. Some will disturb others prefer it that way. I am here for the latter, because the headphones are primarily intended for the sport and I want außenrum already a little noticed especially when I'm out on the road.
By the way, even YouTube videos sound so good. Problems can sometimes be only in normal voices. Since the headphones are curiously, very quiet and the environment is very quiet, you can hear a very slight background noise. Generally I have to say that the volume could be a bit higher. People sitting on the train and wish to listen to an audio book, so might have difficulty understanding the voice still good. On the subject of practicality I say down even more.
Overall, I can state that the sound is still strong and so music is a pleasure in spite of Bluetooth transmission!
-> Convenience:
This is a touchy subject. Ever ahead: the headphones are not necessarily built for little ears. A friend of mine has rather small ears and found the Backbeat Fit soo comfortable to wear. People with average-sized ears are likely but have no problems.
The strap on the ears offer a good grip and not press. In addition, the headphones are easy and they can easily carry also times for an hour. Excellent! Yes, here comes the but. But behind the connecting cable is not that great. When I wear a scarf, a hat or a hooded sweatshirt, it can sometimes be annoying. For as soon as something presses against the cable back, you can feel the strap very uncomfortable press against the ears. For the sport certainly not a problem, because there is usually wearing only a T-shirt, but for everyday life is not the best.
-> Functionality:
The Bluetooth connection is 1A. You can be smart somewhere leave and two rooms next hear everything still super. The buttons on the backbeat Fit can easily be reached, where the on-off switch has come a bit too small. The dual assignment of the buttons, which was already often criticized here once, I do not mind. Everything works mostly fine.
While there are no problems with the connection to the smartphone, it looks for other devices is different. Yes, you can use these headphones also on the laptop, but that's not so easy. Apparently this works namely by no means with any laptop straight away. Some laptops with integrated Bluetooth receiver recognize the Backbeat fit without problems, other strangely not at all. Because you still need then a Bluetooth adapter for the laptop, the 10-15 will increase the price. Then everything works. Still a bit annoying that it is not clear. The manufacturer himself says that the headphones are made primarily for the smartphone and you want to make any comments on the functionality of the PC. Well.
By connecting those headphones with the PlayStation, which brings the way much. While voice chat is working, but otherwise comes to nothing. This means that you can enjoy no sound of video games with the backbeat Fit.
Another annoyance: the BackBeat Fit may not change on the fly, the sound source. Means that they repeatedly until the device to which you want to hear music, first needs to connect. I have it with the laptop connected and start on my smartphone but a song that comes to no sound. I must first disconnect from the laptop and then connect to the smartphone. Although only takes a few seconds, but could also be solved more comfortable.
On the subject of battery: lasts me through quite well. It's not a miracle, because after four six hours, the headphones need to the power outlet, but with this value you can live well.
On the subject of calls: only a temporary solution. Due to the design of the headphones there is no shielding of background noise when the microphone so that the other party perceives every passing car like a thunder. Also, the received sound is not that great. Believe me: the BackBeat Fit do not want to call you often.
Overall, I'm a little disappointed with the functionality. Yes, with the Smartphone everything works, but with the other devices has mans not so easy to convince and also not all of the functions (such as making phone calls).
-> Practicality:
And so we come to the everyday. The BackBeat Fit are really good for the sport, but what about the everyday life? Finally, the price of ~ 90 for headphones is an announcement. Well, actually, these headphones are not soo good for everyday use. The rear cable often times annoying. In addition, the light shielding headphones at stations, noisy streets or to the fullest not bring much. Pity is that this headset can not switch on the fly between different devices and you can easily make calls not. But that is added bleating at a high level! The headphones will not be a panacea and do that for which they are intended, really good.
-> Conclusion:
All in all, this here very good sports headphones that can score with decent sound and good grip. In everyday life, they could inspire me less and that is with regard to the high price a little disappointment. One must decide what you want to use the headset primarily. If one looks primarily sports headphones, you can do with the backbeat Fit hardly anything wrong. Do you need more entertainment headphones for everyday life, one should look at other products.
