Я только что купил пару Bose QC20. Рекламируемые как наушники с шумоподавлением, они на самом деле являются наушниками. Я обычно использую их с моим iPhone. Мой вопрос: вредно ли это для наушников, если я использую их на Mac или ПК? Возможно ли, что разница в напряжении на выходе (не знаю, как это называется) между iPhone и ноутбуком повредит наушникам? Заранее спасибо.
When you buy headphones that come with 3.5mm jack it is designed to be used on all devices that have 3.5mm headphone jack.
Note: I would lower the sound on laptop before plugging the headphones just to make sure that you are not playing them at full blast causes problems to headphones and your ears.
First, no. There won't be any harm in plugging those headphones into your laptop. Voltage tolerances are identical between the iphone and PCs. What is not always identical is the type of plug. The QC20 has a 4-conductor 3.5mm plug which includes ground, left, right and microphone channels. Typical 3.5mm headphones for music & such only have 3-conductors (left, right and ground) There should not be any problems using this, as the conductor used for the mic sits in what would normally be ground. To be safe, or to gain full-functionality, I would suggest investing in something like this: http://www.amazon.com/StarTech-MUYHSFMM-Headset-Splitter-Adapter/dp/B0058DOWH6
This splits the ear-phone connections and the microphone connections into 2 separate plugs. The only down-side is that you won't be able to get any use out of the button. (no way to detect button-press from a laptop)
