使用须知
耳机内含降噪电路。
何谓降噪？
降噪电路能通过内置麦克风
实际感应外部噪音，并将等
量但反向的降噪信号发送到
耳机。
在很安静的环境中，降噪
效果可能不是很明显，或
可能会听到一些噪音。
请勿用手握住耳机的麦克
风。否则降噪功能可能会
无效。
视您佩戴耳机的方式而定，
降噪效果可能会有所不同。
降噪功能主要对低频带的
噪音有效。虽然可以减少
噪音，但是无法完全消除。
当在火车上或汽车内使用
耳机时，视道路情况而定，
可能会产生噪音。
手机可能会造成干扰和噪
音。在此情况下，请将耳
机远离手机放置。
使用须知
请用柔软的干布清洁耳机。
请勿使插头变脏，否则声
音可能会失真。
当需要更换耳塞或进行维
修工作时，务必将耳机送
至 Sony 经销商。
请勿将耳机放置在阳光直
射、靠近热源或有湿气的
地方。
请勿让耳机受到过度撞击。
若要清洁耳塞，请首先将
其从耳机上取下，然后用
清水和中性清洁剂清洗。
清洗后，应先将耳塞晾干
再使用。
耳塞需要时常进行更换。
若耳塞经日常使用或长期
存放而磨损，请更换新耳
塞。
如果使用这些耳机时您感
到头晕或不适，请立刻停
止使用。
将耳塞牢固装在耳机上。
如果耳塞不慎脱落并遗留
在您耳内，则可能会造成
伤害。
耳机的注意事项
避免听力受损
避免戴着耳机用很高的音量
收听。听力专家建议避免长
时间以高音量连续播放。如
果出现耳鸣的感觉，请降低
音量或停止使用。
请勿在驾车和骑车等情况时
使用耳机
耳机会降低外部环境声音，
因此可能会造成交通事故。
另外，在听力不得受影响的
场合，例如铁路交叉路口和
建筑工地等，避免用耳机收
听。
静电注意事项
在特别干燥的空气条件下，
耳朵可能会感到轻微刺痛。
这是由于体内积聚的静电所
致，并非耳机故障。
穿着天然材料制成的衣服可
将此影响减到最少。
如果您有关于本系统的且
在本手册中未提及的任何
疑问或问题，请就近咨询

Precautions
The headphones contain a noise
canceling circuit.
What is noise canceling?
The noise canceling circuit actually
senses outside noise with built-in
microphones and sends an equal-but-
opposite canceling signal to the
headphones.
The noise canceling effect may not be
pronounced in a very quiet
environment, or some noise may be
heard.
Do not cover the microphones of the
headphones with your hands. The
noise canceling function may not
work properly.
The noise canceling effect may vary
depending on how you wear the
headphones.
The noise canceling function works
for noise in the low frequency band
primarily. Although noise is reduced,
it is not canceled completely.
When you use the headphones in a
train or a car, noise may occur
depending on street conditions.
Mobile phones may cause
interference and noise. Should this
occur, locate the headphones further
away from the mobile phone.
Notes on usage
Clean the headphones with a soft dry
cloth.
Do not leave the jack plug dirty
otherwise the sound may be
distorted.
Be sure to bring the headphones to
the Sony dealer when requiring a
change of earbuds or repair work.
Do not leave the headphones in a
location subject to direct sunlight,
heat or moisture.
Do not subject the headphones to
excessive shock.
To clean the earbuds, first remove
them from the headphones, and then
clean them with water and mild
detergent. After cleaning, dry each
earbud carefully before use.
The earbuds will need to be replaced
from time to time. If they are worn
out by daily use or longtime storage,
replace them with new ones.
If you fell drowsy or sick while using
these headphones, stop use
immediately.
Install the earbuds firmly onto the
headphones. If an earbud accidentally
detaches and is left in your ear, it may
cause injury.
Notes on headphones
Preventing hearing damage
Avoid using headphones at high
volume. Hearing experts advise against
continuous, loud and extended play. If
you experience a ringing in your ears,
reduce the volume or discontinue use.
Do not use headphones while
driving and cycling, etc.
As headphones reduce outside sounds,
they may cause a traffic accident. Also,
avoid listening with your headphones in
situations where hearing must not be
impaired, for example, a railroad
crossing, a construction site, etc.
Note on static electricity
In particularly dry air conditions, mild
tingling may be felt on your ears. This is
a result of static electricity accumulated
in the body, and not a malfunction of
the headphones.
The effect can be minimized by wearing
clothes made from natural materials.
If you have any questions or
problems concerning the system that
are not covered in this manual,
please consult your nearest Sony
dealer.
