The A90 can reduce some outside sound through a snug in-ear seal, but it has no active listening ANC or transparency mode. It is a low-cost option for mild background noise, not a strong solution for demanding noise sensitivity.
ProductSearch verdict
A secure seal and audio playback can mask ordinary room sound, while the lack of ANC and transparency limits control.
Silicone tips physically reduce some environmental sound and music can mask additional distraction. Distinct voices, traffic and sudden noises remain audible. People sensitive to pressure may prefer passive isolation, but anyone needing adjustable cancellation or awareness modes should consider a different model.

This comparison distinguishes passive isolation from adjustable ANC.
Buyer questions
No. Its ear tips provide passive isolation, while ENC is limited to microphone processing during calls.
It can soften general room sound, especially with audio playing, but it will not reliably block nearby speech.
No transparency or ambient-listening mode is listed. Remove an earbud when you need clear environmental awareness.
