Nevertheless, I would like to briefly go into details. Within the family, this headset is used next to a BOSE Quitecomfort 15 and a Philips SHB 9100. Of course, the Auna headphones can sound not keep up with the Bose, but he reflected quite "Wacker". So I'm not going to compare the headphones together as this, considering the price, would be unfair.
Charging is done via a microUSB cable and a LED indicates that the battery is charging. Coupling with a BT-enabled device is simple and intuitive. I needed no guidance for it. The first coupling have to press the power button longer until the LED flashes blue / red flashes. After successful pairing the headset is ready for use.
The comfort is comfortable for my daughter, but for me is not the non-padded, but adjustable strap long enough so that the earphones do not sit right on my ear. For many, the length could also be sufficient. The keys to the running intensity regulation require a bit of flair and training. If you, however, this "learned" in a short time the operation is quite simple.
The BT transmission is good, as long as you close the output source (smartphone, MP3 player, etc.) is. Once I have but me 3-5 meters there were "dropouts" in the transmission. Here Auna could easily rectify.
The battery lasts about 10 hours for the üngetrübten music enjoyment. That should be enough for most.
Sonically I have no heights in certain areas and the bass could turn out for my liking "a tad" stäker. For the sport or for people who want to listen to music only, without wanting to hear out the last nuances, these headphones are suitable.
Conclusion: Stability, comfort (for my daughter), equipment and, most recently, the price earning 5 Stars. I prefer a star off because the BT transmission to 100% is not satisfactory and it would be more pleasant for me to have a padded and slightly longer clip (but that's my personal preference and should not detract from the positive impression of Auna Air 300) ,
For the price and the necessary equipment to make sure nothing wrong.
