In the field of audio-visual electronics, Sony is always indispensable. With a budget of 1500 yuan, novices will always hesitate in Audio-Technica msr7 and Sony MDR-1A when buying headphones: is it to recharge faith, or is it female voice poisoning? In the U.S. Consumer Reports, the Sony MDR-1A scored 66 points, and the sound quality is in the "very good" level (the highest is "excellent"). Compared with the msr7, the two are almost the same in appearance, but when you weigh it down, the leather feel of the msr7 is more advanced than the plastic feel of the MDR-1A. In terms of comfort, the MDR-1A performs better, even if the head is large, there will be no chuck feeling, and it is more suitable for long-term wear. If you are a heavy headphone user, then it is recommended that you buy the MDR-1A. In terms of listening, the MDR-1A's low-end is elastic and powerful, while the mid-high frequency performance is passing, which is not as impressive as the MSR7. So if you're listening to "action-beating" rock music rather than vocals-based music, then the MDR-1A is more suitable. In addition, the MDR-1A has higher sensitivity and lower impedance, allowing it to be driven to its full power with a mobile phone.
