I consider myself pretty critical of ANY earbuds. Often they have shortcomings that make them collect in the graveyard of a drawer.What I search for in earbuds:I look for a pair that DOES NOT block out all outside sound. I value situational awareness, and when external sound is all but blocked out, you lose a significant part of situational awareness.I also look for earbuds that are very proficient for phone calls. The person on the other end should hear sound quality that rivals using the phone itself, within reason. It's challenging to have equivalent sound because of the simple physics of a microphone being at ear distance away, versus the microphone on a phone that is very close to the mouth. I also want to have the option to use just one earbud for general phone call use.The Bluetooth earpiece that is my reference in comparing all others is the Plantronics Voyager Edge. It is no longer in production, but it is nearly the perfect earpiece that is so lightweight and comfortable that I forget it is there. It doesn't block out noise from that one ear, and the sound is clear on both ends. It also announces the caller's name if in your phone contacts.The sound quality - Without blocking out external sounds, it can be challenging to have reference audio quality, so I don't expect this level of audio performance. Still, I expect the sound not to be muddy but clear and capable of being cranked up loud enough to clearly hear if the audio source is softer.Comfort - They need to be lightweight and comfortable to wear for hours.Price - Generally, I don't even look at price when it comes to earbuds for my purpose. Of course, once it goes above $100, they have to REALLY be incredible to be worth the price.The simple review:The NexiGo Air T2 earbuds have been a keeper. After about two weeks, I find that I continue to use them. They have reasonably met my expectations, and then some.A deeper explanation:Although the NexiGo Air T2 earbuds have touch controls on the earbuds themselves, they don't get in the way of handling the earbuds. I LOVE IT! These are the first earbuds I've used where the buttons generally don't activate unless I'm intentionally tapping them to control something. It's easy to take one out to talk with someone without worrying about accidentally touching buttons.The charging case is very slim and easily fits into a pocket. This thinness is a welcome surprise because I didn't anticipate just how thin a charging case could be based on the photos on Amazon. NexiGo's claim, "thinnest Bluetooth headset in the world," isn't just fluff.One thing to note, I felt a bit inept when I first opened the box and couldn't figure out how to get the earbuds out of the case. I didn't realize the top of the charging case was open to seeing the earbuds themselves. After looking at the instructions, I found the information I needed. I opened the thin magnetic door to the top of the case, and it exposed the earbuds in all their glory. There's a small piece of plastic to cover the charging ports on the earbuds, so make sure to remove it so they will charge.The audio quality is decent. This observation comes from someone who loves music and making music playing different instruments. There isn't a heavy bottom-end, but that is expected because of the type of earbud it is. The sound is clear and undistorted, even at full volume.Phone calls - I had my wife wear the earbuds, and we talked while I listened to the audio quality. Although the NexiGo Air T2 doesn't quite meet the same level of audio quality the Plantronics Voyager Edge has, these earbuds hold their own. I don't hesitate to have business calls using the NexiGo Air T2, using one or two earbuds.Comfort - I'm VERY impressed the how lightweight and comfortable they are! They are so small that you can be physically active and not feel that one is about to fall out.Bluetooth signal strength - I'm VERY impressed with the range. In a smart home with many devices and signals all over the place, I can get about 50 feet before the signal begins to degrade. I also had my daughter put in one earpiece while we listened to music. She was able to walk away from me about 50 feet before the signal dropped for her. So if you like sharing an earbud with someone, you don't have to worry about someone losing the signal. This test used a Samsung Galaxy Note 10+, so others may have a different experience based on their device used.Battery Live - So far, I have only run a batter down one time, but I'm not concerned because they charge so quickly when dropped back into the case.Conclusion:I wouldn't hesitate to recommend the NexiGo Air T2 earbuds to anyone because I believe they would be pleased with them. At this price point, you will be hard-pressed to find any brand that can out-perform them.For those concerned about buying from a domestic company NexiGo is an American-born brand based in the United States. So far, I've been impressed with any NexiGo product I've bought. Their user manuals are even written in real American English.
