Excellent hearing; I have nothing else to comment on. Pros: There is no comparable product on the market that can compete with this one, both in terms of the features it possesses and the value it provides. The owner, however, needs to have a passion for playing games, an appreciation for listening to music of high quality, and an enthusiasm for the development of technology and the associated gadgets. In the event that even one falls out, the individual in question is no longer in need of these ears. On the other hand, there are phrases such as "that's for 20 would fit." Got cons: It so occurs that there is something wrong with the software, which is buggy. However, this is precisely why they were crafted by experts in ear case design rather than information technology specialists. On the PC, they could also mess with the AptX format. But on a personal level, I am willing to forgive my ears; in exchange for the pleasure I get from listening to music, I will purchase something for them such as the FiiO M7, which functions as a USB DAC transmitter in LDAC.
