SHOKZ OpenRun Mini (AfterShokz Aeropex Mini) -Bone Conduction Open-Ear Bluetooth Sport Headphones - Waterproof Wireless Earphones for Workouts and Running - Built-in Mic, with Headband
I have the mini. Fits my head perfectly with not a big gap. These are the only headphones I can use with my TMJ not hurting me! I use these daily. Phone calls/audiobooks/working out listening to music. 10/10!
