Do not confuse two product categories
An open-ear sports headset and an in-ear hybrid with a bone-conduction element are different designs. Check the wearing style of each product.
Bone ConductionA contact pathway.
A contact pathway.
A different design question.
Explore IEMs described as combining conventional acoustic drivers with a bone-conduction element. Understand why contact and implementation deserve as much attention as the technology name.

What to consider
Contact is part of the implementation
Evaluate shell fit, the stated role and the whole response. A name alone cannot tell you how strongly the component contributes for a particular listener.
Count components, not descriptive tags
Bone conduction is a transmission description. Where a product calls the same component piezoelectric, keep both useful tags without inventing another driver.
Worth knowing
before you choose.
Does bone conduction here mean open-ear?
No. The products here include in-ear hybrids. Check the actual wearing style.
Will it create a wider soundstage?
Do not assume that from the label. Such a claim needs model-specific evidence.
Is it the same in every IEM?
No. Driver construction, intended frequency role and mechanical coupling can differ.
