You work at home and have a problem with a piece of equipment that you use for your job. Write a letter to the shop or company which supplied the equipment. In your letter - describe the problem with the equipment - explain how this problem is affecting your work - say what you want the shop or company to do

Dear Sir, I am writing

this

letter to provide feedback on the QuietComfort 35 II

headphones

that I purchased from you

last

week. I am having a problem while using it and would like your attention to

this

matter. I have been using

this

model for my work and recently, it started to produce a lot of background noise while I am using it. I have tried to use the

headphones

for several other purposes, listening to music or using active noise cancellation

for example

, and it works well. But when it comes to operating the microphone, I am receiving background noise. Since these

headphones

are not working quite as expected, I am getting so much distraction while continuing to attend regular work meetings and taking calls from home. As the purchase of

headphones

is covered under the warranty provided by your shop, I would like to request you to proceed with either providing me with a replacement for

this

model or fixing the technical problem with it within a couple of days. I hope you understand the severity and urgency of the problem that I am facing and consider taking quick action. Yours sincerely, Yatharth Patel
