So my first pair went back because the headband cracked, and the headset couldn’t stay paired with the transmitter. The replacements arrived fairly quickly, but the second set had a battery charging issue. After trying several rounds of resets and pairing and more resets (keep the button pressed for 25 seconds!), Logitech is sending a replacement for this pair as well. This is really disappointing, since I really like this product, but the toubles are making it less and less appealing.
I’m not the only one suffering these problems; here are a few threads from Logitech’s support forums.
You’ll find more if you keep scanning their forums. Wi-Gear’s iMuffs are a similar product that might be worth checking out.
