You are a helpful assistant. The assistant first thinks about the reasoning process in the mind by using Belief-Desire-Intention (BDI) framework and then provides the user with the answer. The reasoning process and answer are enclosed within <think> </think> and <answer> </answer> tags, respectively. 
Below is an instruction that describes a task. After thinking, when you finally reach a conclusion based on the customer's intention, desire and belief, clearly state the BDI thinking process within <think> </think> and then the answer within <answer> </answer> tags.

User Review: The price of these headphones does not reflect the quality of them. They are by far the best headphones I have ever used. Every aspect of these are incredible. The headband is comfortable, the earcups fit perfectly, the folding mechanism is sturdy, and they are extremely portable. The cord is seriously good quality and length, yet the fact that it's coiled means it does not get in the way. Even the plug which is secured by a metal piece rather than plastic or rubber is sturdy.

PROS:
-Extremely clear sounds in all ranges. Background noise in movies such as cars passing behind the camera sound like they are behind me in my room.
-They muffle external sound surprisingly well considering they aren't technically "noise cancelling"
-The cord stays short and compact but doesn't require much force to pull it out to its full length. when it's plugged into my laptop I can pull the cord out to nearly 10 feet without moving my laptop at all.
-They fold up and I don't even notice them in my backpack.
-Obviously, the amazing price for headphones that outmatch Beats by Dre

CONS:
-They attract attention which is good, but people tend to think I paid hundreds for these when In reality I paid $65, yet at the same time I don't want them to get stolen since they do look very expensive.
-They are much louder than most headphones I've used. Once again, this could be a good thing but just be careful to not blow out your eardrums.
-After using them for a while, all other headphones sound really terrible. There is no going back.

Also realize these headphones have mechanical parts inside. After about 3 hours of listening they sounded even better from being broken in a little bit.

Would buy these over and over, and I recommend them to everyone that asks about them.

Update: I found out you can buy replacement earcup pads for this exact model. I don't need them yet but I'm very glad it's possible. The fact that there is a market for replacement earcup pads means these headphones last a long time.

Update #2: The headphones still function perfectly after owning them for a few years. But I have since started wearing a new pair of glasses that have thicker frames than my previous pair. I've found that these headphones are pretty uncomfortable for people with thick-framed glasses, but not unbearable.
