Wired Headphones Basics (continued):
On the cord there is a simple volume control. This is a nice feature as it allows the user to adjust the volume as necessary without affecting others that might be listening. Once the player was set at an appropriate level, turning the volume control here all the way up did not provide any discomfort, however if you are letting kids use these, I would still turn the player down a little and let them turn it up here.
Wireless Headphones Basics:
The packaging for the wireless headphones is similar to the wired model; with the key difference being the color. The wired version is a yellow/orange while the wireless is green/blue. In a retail setting this will help to quickly find the desired model.
As with the wired version, the packaging got a little crushed in shipment to me, but the headphones were undamaged. The back of the packaging once again provides detailed information on the wireless headphones. You have some of the same information as on the wired set, plus details on the carrier frequencies for each ear, that 2 AAA batteries are needed, and the effective operating Range (8m). The 8 meter range is more than sufficient for any vehicle.
Like the wired version these will fold up to be stored, and can also be extended to fit larger heads. On the top of the headband, there is no cushioning. This would be helpful here, as well.
On the left earpiece is the battery compartment. Taking off the cover you need to install 2 AAA batteries, which are not included. Most parents should have a bunch of batteries around, however including them in the package would have been helpful. Something else that would be helpful is making these rechargeable using the car's power. This way if you are on a long trip, you can recharge these when you stop.
On the right earpiece is a power switch. Leaving them on will drain the battery, so make sure it is turned off when not in use. In addition there is a volume control next to the power switch. The audio level was similar to the wired version. Turning them up to full was not uncomfortable. However, with kids always be sure that at full volume it won't be too loud for their ears.
