Krio-Tretirani Jastučići za Uši

Ear pads are the most frequently overlooked komponenta in a slušalica sistem, and the one with the most direct influence on what you actually hear. The jastučić za uho creates the akustički seal između the slušalica driver and your ušni kanal — a seal whose kvalitet određuje the low-frekvencijski odziv, the isolation from vanjski šum, and the volume of the air cavity in which the driver radi. A deteriorated jastučić za uho leaks bass, admits šum, and alters the cavity volume in ways that shift the driver's resonant behavior unpredictably. Factory jastučići za uši begin degrading from the moment they are first used. Skin oils break down the površina materijal. Moisture from perspiration infiltrates the foam. Mehanički compression from repeated wearing trajno smanjuje the foam's thickness and compliance. Unutar six to twelve months of regular use, the jastučići za uši on any slušalica — bez obzira na cijena — have deviated measurably from their original akustički specifikacija.

The Cryo-Treated Ear Pads use viscoelastic memory foam that has been cooled to -196°C in tečni dušik and held at that temperatura for 48 hours prije being allowed to return to ambijentalni temperatura in a controlled okruženje. This kriogeni treatment relieves rezidualni stress in the foam's cellular struktura, which is introduced tokom the manufacturing proces when the foam is cut, shaped, and compressed into its final form. Untreated memory foam sadrži microscopic stress concentrations at the cell walls that cause the materijal to lose compliance over time as the stressed cells collapse trajno pod repeated loading. Cryo-treatment eliminiše these stress concentrations by allowing the cell walls to relax into their lowest-energy configuration at kriogeni temperatures, where the molecular mobility of the polymer is efektivno zero and the relaxation is trajan. The treated foam održava its specified compliance and density for the full 12-month replacement interval.

The outer covering is full-grain lambskin, ručno šiven with a sealed seam that sprečava moisture from wicking into the foam layer. Lambskin was chosen over synthetic protein leather because its natural pore struktura allows a controlled rate of moisture vapor transmission that sprečava the buildup of humidity između the pad and the skin — a uslovi that in synthetic-covered pads eventually saturates the foam and degradira its akustički svojstva. The lambskin's površina is smooth enough to create an effective akustički seal protiv the skin bez requiring the high clamp force that some proizvođači use to compensate for inferioran pad materijali.

Each pair of pads is sealed in a nitrogen-filled foil pouch at the factory. The nitrogen atmosfera sprečava oksidacija of the lambskin's površina oils and moisture absorption by the foam tokom storage and transit. Do not open the pouch until you are ready to install the pads. Once opened, the pads should be instaliran unutar 24 hours to minimize atmosferski exposure prije the first use creates a natural protective layer of skin oils on the lambskin površina. We recommend replacing pads every 12 months or 1,500 hours of use, whichever comes first. Continued use izvan this interval nije dangerous, but to je akustički negligent.
