One hands-on assessment does not detect the unusual plastic odor mentioned in outside customer comments. The headphones smell ordinary to that user.
Pros: Active noise cancellation, Sound quality
Cons: Headband padding quality, Workout heat and sweat buildup
One unboxing report finds a noticeable plastic odor that takes about a week of ventilation to fade. This is an initial-use nuisance rather than a demonstrated recurring problem across owners.
Pros: Comfort during long use, Ear cup padding quality
Cons: Frequency response accuracy, Treble clarity
