Low-noise and near-silent are performance descriptions. A compact shape or discreet appearance does not establish the sound a model produces. Any noise comparison needs an identified model and test conditions.

Do not infer noise from the outer material
A silicone exterior alone does not establish better vibration control or lower noise. Construction and operating conditions can differ.
Keep privacy and operation separate
Appearance, storage, packaging and operating sound address different aspects of discretion. A claim about one does not establish the others. Shipping and order communications need their own terms.
Avoid unsupported pricing and popularity claims
A price comparison needs comparable specifications and a stated scope. Neither quiet wording nor a premium price proves demand or establishes a profitable niche.
Read the specification at model level
The relevant information is the documented operating description and applicable instructions. Bulk quantities do not establish better performance, lower total cost or a guaranteed business result.
