Bests & Worsts Reviews from Amazon

It's been less than 10 months, and the earbud no longer charges. A digital multimeter check on the USB charger pins show that the charger still works, so it's the earbud that is malfunctioning. The earbud performed fine for 3 months (comfortable, sound quality, call times, etc), but soon after, it started to develop low level noise/chirping when not on a call. I initially thought the noise could be associated with low battery charge, but I would need to power cycle the earbud several times after charging to get rid of the noise. Although the noise wasn't very very loud, it was very distracting (about the same level as a low volume conversation). Very disappointing that it doesn't last a year as the earbud was well maintained/stored. I was going to purchase another one of the same model (hoping that this was an isolated defective earbud), but noticed that the price went up, and figure that it might be better to try any one of the competitors' offerings as they appear to be very similar, but more affordable (while offering additional features such as noise cancellation and/or water resistance at the same time). UPDATE (10/3/17): was contacted by company who is arranging for immediate replacement. UPDATE (10/30/17): replacement unit received promptly, and still working very well. Company maintained frequent (email) contact throughout the process and continued follow up to make sure everything is working out to my satisfaction. I was unaware of the manufacturer's warranty when they contacted me, and I assumed that my product failure experience must have exceeded whatever warranty period (if any) there was, but this was one of the first things that the customer service team communicated to me (they gave me the impression they have a real warranty policy..... and are not afraid to use it). This is in contrast to what I imagined: that I would be explaining how the product failed, and how I wasn't an idiot who didn't know how to use it, and somehow would be accused of misusing the device and causing it to fail in a way that is not covered by the company's policy, etc. Instead, I was told that they have a warranty policy, they are very displeased to learn about my experience, and offered a complete refund or replacement with no questions other than "Would that be ok with you?" Excellent service by a company that stands behind its product, and demonstrates concern/care for their customers through their actions. Very unexpected, but welcome high quality of service (just as important if not more than so product quality - especially when there's a problem). As a result, I didn't have to purchase another earbud, and had relatively little downtime. I feel they have earned this update, and I would buy from them again based on this experience, and the confidence they have instilled. I plan to continue to vote with my dollars/purchases for the companies that provide good service such as this one.
