Summary: This is an updated review after trying to contact TDK for support for the pair I purchased. Bought these because they were on sale for a good price. After a few days use one ear stopped working and upon inspection found that the fabric wrapping the cord to one of the ears had freyed and ruined them.
Pros: Decent sound, comfortable in the ear.
Cons: Flimsey fabric cord wrapping frays easily and ruins headphones, customer service non-existent.
Summary: Purchased these because they were on sale at NewEgg, and less than a week into using them the cheap fabric insulation on one of the cords frayed through and no longer works. Contacted TDK for support and received ABSOLUTELY NO RESPONSE. Sad thing is the sound was actually decent and I liked the foam ear pieces because they were comfortable and did not feel like they were going to come loose when exercising.
Pros: Good sound, foam earpieces are soft and secure.
Cons: Cheap quality. Broke in less than a week. Non-existent support.
Cons: One of the cords to the earbud frayed and no longer works. This happened in less than a week of ownership with basic usage. Would actually be decent headphones but now I have a $$$ set of useless earbuds.
Excerpt: Groot nadeel is dat het strijkijzersnoer aan de dopjes zeer ruw en stug is. Dit maakt een schurend geluid en gaat via de kabel naar oren. Je zult echt helemaal stil moeten zitten en niet ademhalen. Anders is dit geluid ZEER storend.
