It is certainly possible to connect powerful headphones to iPhone, but there will be little pleasure from this. The smartphone is simply not capable of pumping large speakers. Earlier we already had the Sound Blaster E1 on the test. Today we are going to tell you about the big brother – the multifunctional sound device Sound Blaster E5. In addition to the amplifier, it is also a portable analog-to-digital and digital-to-analog converter, an external sound card for a computer. In general, let's listen … 
Creative Sound Blaster E5 can be connected to iPhone via Bluetooth. The built-in 3200mAh battery lasts for 8 hours of playback. In addition, there is a standard USB port, from which the smartphone can be recharged while listening. The E5 is equipped with two 3.5mm audio outputs to connect two pairs of headphones at once. In the center is the volume control wheel (pressing it pauses the track being played). 
Despite Bluetooth – technology, lovers of high-quality sound often choose wires. There are plenty of wired connectivity options here. Can connect to Hi-Fi system using line / optical input. Also, thanks to the optical input and output, the device is compatible with media players, TVs and game consoles. And by connecting the device to a computer via a USB interface, you can control the Sound Blaster E5 using a special application. 
The SB-Axx1 processor is responsible for sound processing here. He, in a company with an analog-to-digital converter, converts the incoming signal into digital form and processes this stream to obtain the necessary results. And then, through a digital-to-analog converter, the Cirrus Logic CS439 gives it to the consumer. Therefore, this type of amplifier is capable of showing a signal-to-noise result of 120 dB, which is almost unattainable for traditional analog amplifiers. To test the miraculous device, I decided to watch a dynamic film. The amplifier was connected to a laptop, the default settings were left. So, sound without Sound Blaster E5 and with a card are two big differences. Thanks to the built-in processor, the volume has been added to the sound picture. Low bass also adds atmosphere without sacrificing detail. Due to the fact that the card draws out a low sound level, much more detail can be heard. 
Sound Blaster E5 is a versatile and multifunctional device that will find its buyer among lovers of quality sound.
