Bests & Worsts Reviews from Amazon

See my original review below, then read on for the outcome. I'm convinced Anker is a truly customer and performance driven brand. My original review on February 17th. "I'm pretty much a huge Anker fan. I have many Anker products from batteries to all sorts of cords and I especially love Anker's wall chargers. Like all Anker products, I really appreciate the earpiece build quality. They are beautiful! The cord could be a little stronger and I find the microphone/volume control tends to pull the cord to the right side requiring frequent repositioning. Where I'm going to be critical is audio quality. I find that while they have good stereo balance, the tone is tinny and weak. Even with ear tips firmly in place and volume at 3/4, they have very poor bass performance and no warmth. I listen to a wide range of music from Elvis to Swedish House Mafia. Across the range of music these were pretty bland. Again I love Anker and these seem well built but if the goal is good audio quality these fail pretty bad." February 19th. I received an email directly from Anker regarding my review and apologizing for my experience with the audio quality of my Soundbuds Slims. The rep asked for me to try a pair of their NB10 sport headphones at no additional charge. They did request I send in the Slims for their evaluation and review which I assumed meant they'd toss them or refurbish and re-sell somewhere. They also sent a prepaid USPS label. I let them know I'd hold on to the Slims until the NB10s arrived so I could do a side-by-side to see if there was an improvement. The NB10s arrived and didn't really sit well on my ears and the cord bothered my head and neck. Yes, they have warmer sound and deeper bass but I really loved the fit and feel of the Slims. So I sent a note asking to return the NB10s and keep the slims instead. I then received a new message saying they just made a change to the slims and wanted me to give them a try. They also said keep everything and just give it a shot and provide my feedback. 3/3/17 I received the replacement Slims and they are indeed improved. I played the same track on two iPhones and heard a huge difference in sound quality. They look and feel the same but the sound is much better. Not heavy or fake sounded, just cleaner and clearer. They sound awesome!!!! I have no idea what changed as cosmetically they are same. They are way more accurate. I give Anker an A+ 5 stars for their build quality, audio quality and probably the best customer support in consumer electronics. Thank you Anker!!!! Edit 7/8/2017- Still in love. Battery life has remained consistently strong. I use these everyday on dog walks and while doing work around the house. They've made a couple trips to the gym where they stay put and work well. Even with daily use, they show no signs signs of wear. The cord is still strong, flexible and shows no signs of weakening.
