It is delivered in a high quality cardboard box. The first impression is great, because the device not only looks modern and classy, but is actually a high quality finish. Soft ear cushions and a high-gloss finish on the arms convince immediately. As expected, the bracket can be perfectly adapted to one's head shape. It is controlled via the buttons on the left ear cup. All buttons (many are not) can palpate well with the fingers and use without any time to pick up the headphones from his head.
At the beginning of the power switch is pressed. A visual signal in the form of colorful flashing LEDs and a low tone indicate that the device is now in Bluetooth mode. It can now be connected to a smartphone or tablet.
From the sound I'm really blown away. August, there really brought out everything that goes. About the EP640 Bluetooth headset comes across feeling an always clean tone is present and the height and depth to sound good. The headphones may be a bit bassy for one or two people. I love the bass, just as it must be when I hear music.
I will not explicitly call with headphones. But they are almost too good :-) But if, as happened recently, a call while listening to music arrives, the caller can simply be adopted quickly in between. A hands-free system, ie a microphone is present. Got to be good and of course you'll hear his interlocutor properly.
I hear music for hours until the battery at all times tends to end! A charging takes place via the included USB charging cable. Instead the USB port to use the laptop, I prefer the charge on a mains plug. Move the headset can also be charged by a battery bank.
After several hours, the headphones still presses on the ears or in the head. That's a big plus.
That it is cheap headphones, you can tell by the surrounding noise. Headphones costing 200 euro may hide the surrounding area almost completely. Here this is not quite the case. The environment you can hear when the volume is low. If it is quiet a rum, can also the man who is sitting next to a or is, listen. This is only true in a loud volume.
After several experiences of Bluetooth headphones I dare say that August is one of the best manufacturers in the low price segment. I had already been able to gain experience with this brand and they would currently prefer definitely competitive.
From me a clear recommendation.
