Key Differences

  1. The Technics AZ100 has 4 h more listening per charge

    At 10 h versus 6 h, this is a decisive lead for the Technics AZ100, the kind of difference you notice without looking for it. Ratings usually assume moderate volume and specific settings, so real results vary.

  2. The Technics AZ100 has 4 h more total battery with the case

    You may not notice this one every day, but the Technics AZ100’s 28 h is a step ahead of the QC Ultra Earbuds’s 24 h. The Technics AZ100’s case holds more extra charge, which is handy on trips.

  3. The Technics AZ100 has wireless charging

    Whether it matters depends on your habits, but only one of these two gives you wireless charging: the Technics AZ100. Wireless charging is slower than a cable, but it’s about convenience rather than speed.
