This 1moreibfree is a Bluetooth headset. I believe everyone wants to know its sound quality. Bian Xiao evaluated the sound quality before and after/kloc-0 1moreibfree. Let's have a look!
Sound quality experience before cooking
The music introductions selected in the audition are all ape lossless audio tracks pulled from the hivi audition CD.
Cai Qin's "ferry": mainly testing human voice and low-frequency dive state;
Albert Au's "I just like you": the strings and piano scores used in the soundtrack can test the performance of headphones at high frequencies;
Liu Xing's Lonely Crane in Idle Clouds: Test the separation degree of three frequency bands of headphones;
Karajan's "Radsky March": The symphony mainly tests the sound stage of headphones and the control ability of big dynamics;
Liu Lianglu's As usual: Test the performance of male voice in headphones.
Listening experience before cooking: the biggest problem of iBFree is that the high frequency is too scattered and pricking, the middle frequency is regular, and the low frequency is not deep. Let's talk honestly about machines.
Sound quality experience after cooking
After cooking, I felt the real charm of iBFree.
The tri-band level has improved, and the low frequency has gone down. The middle frequency is mellow, and the male voice makes the high frequency more delicate, which broadens the whole sound stage. However, the depth of low-frequency dive is still insufficient, there are more middle and high notes, and the overall sound quality is thin. Personally, I feel that this earphone is more suitable for listening to human voice and classical music. If used with ViPER4 Viper sound effect, turning on dynamic low frequency can also make up for some low frequency deficiencies. But for Bluetooth headsets, it is very satisfying to have such sound quality.
