"Ordered KSC35's almost about 1 and a half years ago. (November 17, 2003)I had to send it in for warranty repair this June as one of the clips broke. Before I sent it in, I emailed Koss asking if they would replace my KSC35's with another pair of KSC35's, and NOT KSC75's. They said this was o.k., as long as I included a copy of the email in the box. I did this, but I received the KSC75 as replacements anyways. Since then, I have sent them two emails, and they have not responded to either.
In the letter they sent me, they said they felt the KSC75 was of equal price/performance as the KSC35. This is not true, as the only place to buy the KSC35 is from www.koss.com for $36 (including shipping,) whereas the KSC75 can be found from a multitude of retailers, including Circuit City for as little as $10 - 15. The KSC75 sound worse too. As a result, I feel ripped off and as if Koss has not properly honored their warranty statement. Worst of all, they lied to me, saying they would replace my KSC35 with another KSC35, but instead sent me KSC75. When I try to explain the situation to them, they do not respond. In the included letter, Koss said that the KSC35 was discontinued and that is why they sent the KSC75. However, even though production has ceased, Koss still has some KSC35 in stock, as evidenced by the fact that they are still selling it on their website. If Koss does not want to send me the proper headphones, they should at least compensate me monetarily for the difference in price between the KSC35 and KSC75. This is terrible customer service in my opinion, and I will never buy from Koss again. I posted about this situation on a headphone enthusiast forum, and it seems Koss is starting to build a bad reputation there too.
By the way, the reason I could not include the Invoice number is because I switched ISP's from AOL to Comcast since I bought the KSC35, so I do not have the original email from November 2003. The printed invoice I got with the package does not have an invoice number on it. If Koss read their emails, I'm sure they could easily figure out who I am.
Edit (7/26): Koss emailed me back finally and said they would take the KSC75's back and send KSC35's. "
"Ordered a Sparkle plug from Koss.com website.
Firstly they said my card is invalid and didn't notify me by email or phone.
I called them almost one week after to find out what's happening.
Solved the credit card issue, received my product quickly.
Then it charged me $9 more. I called them again on 10th May to find out they mis-charged me for shipping fee.
And they said they will credit $9 back to my credit card.
I still didn't receive the credit till today."
"Koss is one of the only company’s that still offer a "no questions asked lifetime warranty" and they really mean it! I've owned one pair of their headphones for over 2 years and have broken them twice (my fault) and within a week of sending them in for repair I will have received a new pair, yes new, you can't beat service like that. I plan on buying their top of line headphones later this year mainly just to support such a great company.
I also love the headphones (the R/80s) great sound and very comfortable.
Buy Koss!"
"Very prompt with shipping.
Didn't respond to emails at all.
Needs work in this area!!
Koss could take note of how NewEgg does business.
Really nice headphones, too!!! RB-65's"
"I ordered their KSC-35 headphones which are highly rated. The only problem is that they charge your credit card even if the item is backordered. I sent them an e-mail about this, but they never responded. Nevertheless I'm satisfied with this purchase."
