Question: Are these waterproof? as in I sweat heavily during workout. Can this bear that?
Document: So, why am I saying that these are waterproof? Well, last night I (accidentally) completed a swim workout with these in my bathing suit pocket. Swam for 30 minutes in a lap pool, so these were MORE than soaked.Right after I exited the pool I noticed my error and popped them in, and they sounded almost perfect, albeit it sounded like the band was a little far away.
I had them for a month before the controls (volume/pause/speaker) intermittently stopped working. Don't buy these if you want to wear them during your workout and you sweat alot during your workout.
And of course, I'll never sweat or otherwise workout with my beloved Shure SE530's.
The design is also ideal for working out. The style that plug the ears tend to slip out when sweating, whereas this design won't because of the entirely different way it is secured against the ear. If running or cycling, it is highly desirable to be able to hear cars before you find yourself under them.However, if you want sweat-proof, stay-put workout ear buds that allow ambient noise into your ears, the Addidas/Sennheiser MX685.
I got these as a Christmas gift and I've used them heavily for the past few weeks and have never been more pleased. They fit comfortably, have a great range of sound, and the design is very simple yet stylish. I've owned an $80 pair of Skull Candy's and a $150 pair of Klipsch in-ear headphones that still didn't sound as good as these do. The only gripe I have is the bass.
I did not pay the extra for the waterproof sports version of these headphones, because I was unsure if I wanted to front the extra money just to find out I didn't like the headphones. But so far after a month of almost daily use in the gym, I have not noted any durability issues.
These heavily outperform any earbuds (earbuds, not necessarily IEMs) you could find on the market by a huge margin. So if you have small canals like I do (and endless trouble with typical canalphones), these are your best option. They are a little overpriced imo, but the fit is amazing and sound quality is excellent.After reading previous reviews, I've heard mixed opinions of the bass. To me, it's fantastic. Not overpowering, but certainly not lacking unless bass is all that matters to you.
Bose had a great product with the IE2 headphones. Sound was amazing, the ear flap thingie works pretty good for when you are working out. I changed those ear flaps to other silicon in-ear tips i had laying around (from another monster headphones) and the sound quality increased quite a lot. However, if you are like me, a heavy user that likes to listen heavily to music everyday, be warned that this headphones will not tolerate the use and abuse.
I bought these a few months ago, and love them. I can go to class in them and still hear my surroundings. Perk, when I go workout they fit snug in my ears, the clip-on works wonders also with working out. Very satisfied.
I am an avid workout-aholic including weightlifting, plyometrics, running, and circuit training.. These headphones are great! They don't pop out of your ears, the sound is great, bass for ear buds are excellent (Bose bass), and they are comfortable for hours!
Answer: Yes they are fine during heavy, sweaty workout
