Master & Dynamic MW07 True Wireless Earphones - Steel Blue

I purchased a premium set of earbuds (MW07) only to be disappointed. First, the left earbud would not charge in its case and had difficulty connecting. Second, the audio quality was okay but the base was too low: I used these for the gym. Third, the volume is super low and did not get the range I needed; again gym setting. And lastly, there isn't an app to modify or tweak any settings. Can't imagine you can update firmware because there's app. Save yourself the hassle and look elsewhere for new earbuds. The 250-300 price tag is way too high with all its flaws to include a 3-3.5 hour battery life.
