Question: Is this item covered by Shure's warranty?
Document: Good sound, poor quality. They sound great and are reasonably comfortable.The build quality leaves something to be desired, however. The sound in the headphones began to cut in and out 6 months after I received my pair. I sent in my cable for replacement under their 2 year warranty. Shure 'never received' my shipment to them for my warranty claim. Be warned: if you submit your item for warranty repair, it may be lost in the ether.
Shure wires seem quite sturdy so I have hope. The two year warranty is a big plus and when they do wear out. I'll only need replace the wires v. the entire set. Excellent idea!
I have been using Etymotic HF3 for the past few years. Unfortunately, even though Etymotic's sound quality seems state-of-the-art, it breaks down once a year. Thanks to the 2 year warranty, I only have to buy a new headset every 2 years, but after my second HF3 was out of warranty, I decided to change my brand. I searched for a new headset which both had amazing sound quality and durability.
I loved these headphones until they started failing. Send my right bud back to Shure to get it replaced under warranty after only 6 months. They gladly and quickly replaced the bud sending me a new one. I was satisfied at that point until 10 minutes ago when the ear bud failed again. This time the cable wiggles. I believe the cable connection is poor this time; last time the speaker in the ear bud had failed.
The cable works, but it is of notably lower quality than the stock cable that comes with the 215-K earphones. I like the earphones a lot, but it is irritating that there is not a higher quality, more durable cable option that includes a microphone.The insulation covering the connection between the cable and the plug on my item wore away completely after about a year's use, right where the cable first meets the stress-relief fins.
I have had these for around 6 months and have already had to return them due to the cable going bad. They sound pretty good, I would say slightly better than the SE115m+. I have owned multiple pairs of Shure, Sennheiser etc. over the years and came back to the Shure's again for their full range of sound for a decent price.
they are a bit awkward to put in at first but they do a good job at blocking sound and the audio quality is superior (better base ) than etymotic er7 mc3 which i bought along with this.
sound quality is very good.not a big fan of the behind the ear design.Doesn't look as cool as the Boss head piece.
no alligator clip that comes with it and its cable is a little thin  also, the remote/clicker is a bit large and takes time 2 get used to it as well as in trying them on could b e a challenge 1st few times and taking/receiving calls are clear but the people who are on the otherside always knows and notes im on headset like as if they could tell you are on loud speaker but worth all the hustle! no risk, no reward ;)
neither worth more than 50 bucks.
Answer: Yes. I have already had to send mine in as the cord died once.
