When it is safe to do so, I often wear earbuds when running. Although I owned audiophile Shure corded earphones, I've found that the freedom of not having a cord to worry about getting caught in a zipper or wrapping wires around my ears leads me to wireless earbuds. I've refused to consider Bose or Beats models simply because I don't patronize companies that spend more on marketing than on product design. I purchased a pair of Sennheiser True Wireless earbuds and while the sound rivaled that of the Shure audiophile corded earphones, I had 3 pairs crap out and stop working over a period of 18 months. I've now owned a pair of Jabra Elite Active 75t earbuds for about a year and I'm extremely happy with them. The battery lasts long enough for a 4 hour run. They handle the odd phone-call reasonably well. Audio quality is good enough for podcasts and most high resolution formats. I see that Sennheiser has introduced a 2nd version of their earbuds - do they work reliably?
