A few weeks ago I once again had the pleasure of having to buy new headphones. After long back and forth I have this time to step in a Bluetooth headphones test.
Ultimately, I decided after some research for the EP640 from August. So far I am very satisfied with the purchase. The sound is good and the headphones are comfortable.
The scope of delivery includes the following components:
Instruction manual Multilingual
USB cable for charging the headphone
Jack to jack cable gilded to connect if the battery is empty
The processing of the headphone is stable and the hinges for the folding of the auricles are also useful. I myself use the headphones at work and on the train ride, where I move rather less. But the headphones are great. As these e.g. while jogging, I cannot judge.
Here are some technical details.
- Bluetooth version: Bluetooth v4.0 + NFC
- Range: Up to 10m
- Frequency response: 20Hz – 20Khz
- Speaker Output: 10mW
- Signal-to-Noise Ratio: 113 ± 3dB
- Distortion: 1.0%
- Battery: 3.7V / 220mAh Built-in Li-ion battery
- Working time: 10 hours
- Duration: 2 hours
- Standby: 12 days
- Weight: 241.6g
- Dimensions: 194 x 186 x 70 mm
NFC I have not used here yet. For this I can say that the headphones works without problems with the iPhone, iPad, Macbook. There are no problems with the included cable. The only drawback is that you cannot charge and use the headphones at the same time. This creates a very unpleasant noise.
I do not regret to buy the headphones. For this price, it is definitely a good product and the recommendation value.
