\once you read it you will not want to install or use 5G. If your just getting into your training, do yourself a favor and spend an extra couple dollars on this pair, it (feels like) it will last you for years and not leave you sore after longer cross country flights. Theyre too expensive to be one-time use, so Ill be trying another brand or go back to my bandaids. I?ve wanted a pair of waterproof gore tex sneakers for winter travel with black bottoms, found them! Affects, mid-range and bass are top notched. I am still very pleased with this speaker and like the "new" sound even better now. They are awfully thin and Im concerned about wear and tear (maybe this is why they send a second set). The only issue I have with these is the sole material. Lovely and silky and just what I was seeking. To mitigate this I have worn good shoes and in some cases, where I may be on my feet all day, Ive donned compression socks to avoid painful swelling.
