Built rugged for classroom use, the HPK-1000 USB headphones from
Califone seems bulkier and heavier than it actually is. The headphone
sells for $76 and features a "comfort strap" headband for longer
wearability. If your student spends a long time in an online classroom,
this is a standout feature.
The HPK-1000 features Califone's "Sentinel Technology" --a limiter
built into the volume control that keeps the volume levels at or
below the recommended 85 db. A red light on the volume control
indicates that this technology is enabled.
The earcups have soft foam cushions and fully cover the ear, filtering
out distracting noise. However, these are not noise canceling headphones.
The detachable cord has a built-in in-line volume control. This
is the first washable headphone, and it cleans easily with the
cord detached. The durability theme is carried out "inside" the
earcup as well. There are slotted baffles to protect the speakers
Califone products are designed for durability in an institutional
setting. With normal care and maintenance, this may be the last
headphone you need--unless you decide to upgrade to a headset equipped
with a boom mic. Califone offers two such headsets, the HPK-1010
and the HPK 1510.
