Review on Bundle: Sony MDR7506 Closed Ear Headphones with Knox Gear Compact 4-Channel Stereo Headphone Amplifier - Professional, Folding Design (2 Items) by Jasmit Chitkara ᠌

We had at our disposal: a Samsung Galaxy S7 Edge phone, an iPad 2022 9.7 and a computer with a Realtek sound card built into the motherboard. The same music participated in the tests - a playlist on Apple Music and several tracks in Flac format (for example, Queen, ATB, Modern Talking, Twenty One Pilots, Nickelback, Robert Miles). I connected it to the computer, the sound is not bad, the volume is enough to comfortably listen at the maximum (that is, in fact there is not enough volume, you always need a margin, since some tracks are quiet), but in some tracks at low octaves the soloist's voice was distorted into a robotic - not pulls out the built-in sound. I connected it to the phone, checked the same moment with distortion - there was no robovos, the volume level was about the same, but the sound itself became flatter - it also does not pull out the chip in the phone. But on the iPad, the headphones played well, the volume was more than enough, there was no robotic sound, and the sound itself became more voluminous and detailed. There is also an assumption that the iPad does not reveal the full potential of the headphones, you will need to check the work with external sound cards for PCs of different price ranges and compare it with the sound from the iPad - I will write in the comments when I come to the final conclusion. Conclusion: if you are planning to purchase headphones for listening to music at home / in the studio and there is a good signal source (hi-fi player, home cinema, external sound with a good DAC, etc.) or are ready to buy it in addition, then these headphones will show themselves from the best side and give a lot of positive emotions.
