I have the Phantoms and agree Grace's team at OtoPro is great. I wouldn't buy the Phantoms again until they come out with another generation (for example, Santa won't be leaving these in my sons' stockings). Two complaints, pretty fundamental. First, the devices automatically turn on when taken off the charger. This is a great feature for hearing aid you'll put in immediately, but a terrible feature for devices that then go in a case, in your pocket, in your truck, and maybe finally worn hours after leaving your charger behind. IF they had a visual indicator they were on, say a lit diode or a switch that positively identified On and Off, this would be easy to fix. But to effectively turn them off, you first need to put them in so you can hear the tones as you try cycling the momentary contact switch. But about half the time putting these in, you'll activate the switch itself. If they were off, you might accidentally turn them off. If you managed to get them turned off, you might well accidentally turn them on handling them out of your ears. These really need a positive on/off switch, not a momentary contact switch, and ideally not a multifunction button that also cycles through the programs. Second, their little magnetic mount charger case seems slick until you try to store the devices with the lanyard on. The case simply doesn't have enough space inside to hold the lanyard (which always protrudes somehow). In the event you can get the lanyard all wrapped up and inside the case, it's likely that you've then knocked the earbuds off their little magnetic chargers. So it's a lot of trial and error. You can take the whole charger with you in your truck, but set the device gently on the dash and periodically check that both charging LEDs are on (better yet, plug the case into your lighter), because it's easy to jostle the earbuds off the magnetic charger posts. You would never put the charger case in your parka pocket, for example, or you'd jostle off the charger which would turn the units on, which would run down the battery. A positive charging connection (micro USB) would be ten times more useful. Suffice it to say, these are very expensive passive hearing protection when all these design flaws lead to dead batteries when you thought you were doing things correctly.
