Review on 3 Pack Audio Headset Extender Compatible with Smiphee iXCC Trianium, Charcoal Gray White PowerBear Cell Phone Battery Charger Cases for Galaxy S7, S8 Bulky Battery Packs: Buy Now! by Nick Brunner

They are too short and I would like to buy others a little longer as it would be more comfortable for me. I plug them into the audio mixer to try and save ports on the mixer so I don't plug and unplug plugs in the mixer. If they were 0.5 cm longer, it would be better. I saved myself a few bucks, this is the best price. Otherwise the quality is impeccable. No problems at all for half a year. A good product.
