Key Differences

These differences may help you make a decision.

Form Factor: Circumaural vs Supraaural

This is one of the most crucial aspects when picking between the Plantronics 655 and the 628. The former is considered a “circumaural” or “over-ear” headphone, which means that both ears are contained, covered, and sealed. This mechanism helps prevent external noise/sound from coming in.

On the other hand, Plantronics 628 is a “supraaural” or “on-ear” headphone, which is the opposite of 655. Your ears are not covered, and the pads are pressing against your ears. This pressure makes it uncomfortable after some time. Plus, since the pads don’t seal your ears, external noise is a concern.
