Wireless headphones are an increasingly popular option. In fact, last year Bluetooth headphone sales surpassed those of traditional wired headphones in the U.S. for the first time. Headphone jack or no headphone jack, going wireless is convenient and gets rid of that annoying cable that snags on everything and gets tangled into a knot at the worst possible times.
But, going wireless means batteries. Bluetooth headset batteries usually apply lithium-ion batteries. Lithium-ion batteries can explode and catch fire. With the report of Bluetooth wireless headset catching fire while being worn by a woman on a flight from Beijing to Melbourne --causing burns, smoke and singed hair-- many people are now looking suspiciously at their cool new Bluetooth cans.
There are some simple steps you can take to avoid becoming the next victim of exploding Bluetooth headphones.
How to Keep Your Wireless Headphones from Exploding
1. Avoid the cheap, no-name Bluetooth hands-free headset. There are hundreds of these headphones available online. When they’re ridiculously cheap, there is obviously cost-cutting going on. Some savings may be achieved through inexpensive audio components (in which case they will sound terrible, too), but manufacturers may also cut corners on the lithium-ion batteries or the charging circuitry. Do you want those batteries strapped to your head?
2. Use a protective case when packing. There’s a natural tendency to jam headphones into a bag as an afterthought. You could get away with this with wired headphones (aside from some scuffs), but lithium-ion batteries that get crushed or have pressure applied to them can suffer from a short circuit that leads to a fire. When packing your Bluetooth stereo headset, use a protective case to prevent this from happening.
For example, Mixcder new noise cancellation Bluetooth headset MS301 is packed in a sealed black case from the picture as below, so accidents would be avoided because of this.
3. Avoid dropping, sitting on or otherwise physically damaging your wireless Bluetooth headphones. As mentioned above, lithium-ion batteries don’t react well to pressure or being poked with sharp things. Sitting on wireless headphones, dropping them down the side of a seat, accidentally stepping on them --any of these actions could physically damage the lithium-ion battery, increasing the risk of fire.
4. Use an appropriate charger. Most cordless headphones come with a Micro USB cable for charging from a Smartphone charger. Unless the manufacturer specifies that it’s okay to do so, avoid using fast-chargers and stick to name-brand charging solutions. A cheap charger that’s underpowered can damage the headphone battery; one that sends too much current could potentially make the Bluetooth headphones explode.
5. Don’t charge in extreme temperatures. Lithium-ion batteries can be sensitive to temperature extremes, and charging when it’s very hot adds to the thermal stress. That can damage the Bluetooth headset batteries or, in a worst-case scenario, could result in a fire.
6. If you see any swelling on the headset, stop using them. When lithium-ion batteries fail, they often begin to expand. Eventually, this can lead to a messy rupture or even a fire. If your wireless headset show any sign of swelling, safely dispose of them.
