Once a week we dip into the tips box and share some of the great reader tips that come our way. This week we’re looking at protecting your ears with automatic volume adjustment in Android, a compact way to take advantage of Windows ReadyBoost, and secure phone charging on the go.

自動調整媒體音量，以便在android裝置上使用耳機

Javier寫了以下小貼士，讓你在換耳機的時候不至於爆耳朵：

I frequently use headphones with my Android phone while commuting on the train and sitting at my desk. It’s super annoying to have the discrepancy in volume between the phone’s speaker and the headphones be so high that it startles you and/or hurts your ears. For awhile I would just turn the media volume all the way down, then plug in the headphones, then adjust it back up… but that’s a waste of time! I found this great app, Hearing Saver, to do the work for me. You install it, run it once, and adjust the volume to your comfort level with the headphones plugged in. You can even set it to mute the ringer and notification sounds, as well as adjust the volume to a certain level when you unplug the headphones. It’s a little thing, I know, but it saves me a few minutes of fiddling a day.

很高興找到Javier；我們非常喜歡解決煩人問題的簡單應用程式。這個看起來像是解決了揚聲器/耳機的差異問題。謝謝你的來信！

為windows readyboost使用計算機sd卡插槽

Tony寫了以下關於從未充分利用的SD卡插槽中獲得更多里程的提示：

I never use the SD card slot on my Windows 7-based laptop. I’d been experimenting with Windows ReadyBoost and I found that it actually helped out. The only problem was that I hated having a big USB drive sticking out of the side of my laptop. A few days ago it dawned on me that I never used the built in SD card reader which is really just a skinny USB drive, when you think about it. I grabbed a cheap and decent sized SD card from Amazon and now I’ve got the boost without the bulk!

膝上型電腦上的SD插槽實際上是為此而生的。對於不熟悉ReadyBoost但對膝上型電腦有興趣的讀者，請務必檢視我們以前的指南，以使用SD卡和ReadyBoost來提高上網本的速度。

旅行時安全地為**充電

比爾是一位經常出差的人，他在信中寫道，要讓你的智慧**保持充電和安全：

I fly all over the country for my job and put some serious miles on my **artphone. I need to top up the battery frequently but I’m paranoid about losing my phone and/or exposing it to security risks. Here’s my two-part strategy:

I always have a **all wall charger that accepts the battery for the phone. This way I can plug in the primary or secondary battery into the wall without having to leave the phone tethered to the outlet. Nobody is going to steal a non-descript battery plugged into an out of the way outlet at the airport… where as they would definitely steal a nice **art phone.

I also keep a power-only USB cord with me. Maybe I’m paranoid but I don’t like plugging my phone into those USB charging stati*** that are popping up around airports. Sure the port is probably just a power port with no data connection… but I’m sure we’ll here about machines that push malicious software to the **artphones attached to them at some point in the future. By using a power-only cable (the cable only has the wires for power, not for data), I never have to worry about that.

很好的小費比爾，我們特別喜歡壁式充電器的主意。只有一個電池插著，而不是整個智慧**，我們會更舒服。
