The microphones are, in general terms, superior than those of any other in-ear TWS that I have ever used. The transparency mode feels very authentic; however, the most recent firmware causes the headphones to obfuscate the transparency when there is a consistent background noise, such as an air conditioner operating above your head; as a result, you are unable to understand what the other person is trying to tell you. Yet in most cases, this is just a benefit: it does not stun the user in the wind, in the roar of a passing truck, or in other similar situations. AAC is the only normal codec that is available for playing sounds other than speech on phones that do not support Scalable. This results in a delay that is already slightly noticeable, and the sound itself seems to be slightly degraded. But, it is also cool. When it comes to the sound, it has the most pristine highs, crystal clear voice, and great lows. The low ones are great for use with smaller TWS in-ear headphones; however, if you place a high priority on having a deep and vibrating bass, you should not use shorties because their dimensions do not permit this and you should consider full-size headphones instead. Noise reduction is not only pleasant, but also beneficial; for example, while listening to music earlier today, I was not aware of a truck that drove directly up to me and waited for me to cross a portion of the local territory. The functionality of headphones is significantly altered by the firmware. All of this is correct for the most recent firmware version at this time. With earlier versions of the firmware, there was a greater degree of transparency, but there was also a "robot effect." The noise cancellation was more effective, although wearing them caused discomfort in the ears, much like wearing plugs would. The newest version of the firmware includes a tap-to-control-volume feature, the sensor has improved its responsiveness, and the filter for unintentional clicks has become more intelligent. It seems as though there has been some modification to the sound. In general, eating is essential because it brings about a significant shift. When you make a purchase in Galaxy Wearable, you should not delay in selecting an equalization setting to use. To my ears, it has a lifeless and uninteresting quality when performed classically. You can also try on some of the different ear cushions that come with the package; I found that the sound was even more satisfying with the larger ones. And perhaps most significantly, you need to be familiar with the technique for correctly inserting them into your ears. You are unable to close the external grids and microphones once you have started the process of closing the channel.
