system
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: I really wanted to like these headphones.  I got them for Christmas after doing a fair amount of researching and decided that, for the money, these would work fine.  I was also impressed by what people said about JLab's customer service.  When I listened to the first pair, I noticed that the right earphone would cut out to roughly 25% of the volume.  As I would adjust it, the sound would return so I started the process of burning them in.  They actually burned in pretty well and I enjoyed the sound, but the cutting out was still bugging me so I wrote to JLab about it.  They told me to send my old pair in and they would send me a new pair and, much to their credit, they sent me a pair right away.

The second pair was immediately worse than the first.  This pair cuts out in both ears and there is a crackle like a metal membrane being flexed.  Their response was that they couldn't get the first pair to recreate the problem I was describing so I thought that it might just be me.  It feels like the back-pressure is causing the problems so until it's seated just right I don't really get any decent sound.  Resting them lightly breaks the seal which kills any bass.  (These have never really seemed to burn in as well as the first pair either.)  I responded with a request for any kind of recommendation which was answered with the question of whether these problems occur without the silicon pads.  Since the pads created the seal and the pressure it doesn't so that didn't really help me.  My third email has remained unanswered and I'm just tired of dealing with it so I'll keep them and they can be the pair I sometimes listen to.

I have determined that the issue isn't entirely me since I just bought a similar pair by another company that ended up costing less than half the price and they have none of the issues I just mentioned.  In fact, aside from their lack of a really clear mid-range right now, they sound just as good as the J3s.  Overall, the correspondance with J3 was very pleasant, just lacking in the end.  I just wish they could help me figure the problems out so I could be happy with them.

Overall they do sound good pretty good.  This pair lacks a little of the bass and is a bit strong in the high range, but it's a good, clean sound which I appreciate for vocal music.  The size is good and the case is nice.  (I also ended up buying their Samba case for my iPod Touch.  It zips backward and seems upside down but works really well for what I wanted it for.)  The cord is a little short, but most of the time it doesn't both me.  Cord noise is a problem, but I'm usually sitting still when using them.  Ultimately they're a decent headphone that I think I've had really bad luck with.  The company seems willing to stand by their product...to a point.
