Sony MDR-ZX330BT Bluetooth Wireless Headphones with NFC Connectivity - Black

Product Information

Follow these steps if you can't hear any sound from your headphones after playing audio from a connected source device. In this case, do not disconnect the micro-USB cable from the headset: wait a few minutes until the indicator (red) lights up. For when I’m in the midst of my workout (especially on my run [I really dislike running]) I honestly don’t pay too much attention to the fine details of the audio whereas the beat is my main focus and that’s precisely what these highlight on.

Depending on the ambient conditions in the area where you are using the headset, intermittent sound may still occur, even if the “Priority on stable connection” mode is selected. They're big and they cover my ears completely, which is better than a pair of Marshalls headphones which left parts of my ears poking out and made the experience a little less pleasant. A device featuring the BLUETOOTH function is required to conform to the BLUETOOTH standard specified by Bluetooth SIG, Inc.

If the headset is not used for a long time, the indicator (red) may not light up when you connect the micro-USB cable to charge the headset. Do not use the headset in places where it would be dangerous if you are unable to hear ambient sound, such as at railroad crossings, train station platforms, pedestrian crossings, and construction sites. What I like is that the blue light flashes only once every five seconds, as opposed to every second, like some cheaper headphones do. Pairing is the process required to create a link between BLUETOOTH devices to allow wireless connection. I feel great energy when the violin peaks at its highest notes and even during my workout I could get the adrenaline from the music from the higher notes I would be listening to, so at least in the treble I was quite impressed.

Note also that even if the same profile exists, devices may vary in function depending on their specifications. A built-in Li-ion battery delivers approximately thirty hours of power (depending on your music settings ), and is rechargeable via USB.

Due to the characteristic of BLUETOOTH wireless technology, the sound played on this unit is slightly delayed from the sound played on the BLUETOOTH device during talking on the telephone or listening to the music. When you pair the headset with devices again after initializing or repairing the headset, information for pairing with the headset remaining on the iPhone or other device may prevent you from pairing them successfully. Also the drivers themselves have great durability; I know this as I've dropped them multiple times without them breaking. When the remaining battery charge becomes low, the indicator turns from blue to red, except for pairing mode.
