Sennheiser Adidas Sports CX 680i

Anonymous, Newegg
27 February 2015
  • Summary: I'm still in limbo as to weather I should buy a pair of the CX 685's and give them a try. They're certainly cheaper.
  • Pros: Please read this. The headphones fit fairly well in my ear canal and if you are like me and the biggest concern you have is keeping your ear buds in while running then they will most likely do the trick for you(I run about 4-10 miles a day at a 6:30 mile pace depending to give you some reference)...
  • Cons: The headphones did not work. I plugged them into several audio devices and received a very muffled sound. I tried them out for a couple of days to see if they would work and they didn't. I have heard the sound quality from these headphones while using a friends pair and it was "decent". Also the ...

If it weren't for the cables...

Amanda D., Newegg
15 July 2014
  • Summary: Since the volume control on the extension cable is bulky and the extension cable is basically required for the cord to be long enough for my use, I've started hooking the cord over my ears, and this seems to eliminate any downward tug from a bouncing volume control if it comes unhooked.
  • Pros: Pros: The sound from these headphones is rather good for the price. They are not uncomfortable once you find the right earfin/earbud combination for your ears. With how good a fit they are, any external sound is incredibly dampened, if not eliminated. They don't slip when jostled.
  • Cons: The cable situation is a bit frustrating. The earbuds come with a cable measuring a little over two feet, and then an extension cable is included, also a little over two feet. The extension cable comes with a rather bulky volume control box for being a "sport" model, and it comes with a clip to s...

Great sound, bad quality for a "sport" headphone

Samuel D., Newegg
24 February 2014
  • Pros: The sound on these is great. Good bass, clear highs, one of the better pair of earbuds I've owned. The cable is long and the volume control has a plug so you can lose 2 feet of cable if you wear your phone/mp3 player on an armband. They're pretty comfortable, too, and the earfin system keeps them...
  • Cons: The durability on these headphones is a serious issue. I was smart to purchase the extended warranty, as I've had to send them in 4 times in the past 18 months due to losing sound in one or both earbuds. It's always due to the connector at the volume control too-must be a weak point in the design...

Fantastic Product

Harris A., Newegg
8 May 2013
  • Summary: Used these for lifting, running, and crosstraining for the past 18 months. Was very happy with the sound compared to other sport headphones. Was more than pleased (read relieved) that they actually stayed in my ears during activity once I tested out a few different fitting pieces to find the correct...
  • Pros: Decent sound for the price Stay in ear with the correct fittings Very durable
  • Cons: Might take some personal habit changes to make them work for you Volume control is the weak link in this chain

Amazing EARphones

Claudio M., Newegg
10 November 2012
  • Summary: If Sennheiser redesigned the cord and the extension cord, this product would be worthy of 5 eggs. Unfortunately, a small amount of hassle steals it's pride D: However, if you are the kind of guy who prefers to listen to .wavs and .flacs over MP3s, and who needs some earphones that won't fall out...
  • Pros: The sound is definite and clear, stereo channels are seperated perfectly, listening to the human voice and any guitar work is dreamy. If you aren't listening to audio files with a higher quality then MP3s, now is the time, you won't miss a detail while wearing a pair of these beasts. The "sealing...
  • Cons: The extension cord. I can tell you without a second to think that any problems with using the 680i is centered around the extension cord. First off, the cord attached to the earphones themselves is way too short unless you have your listening device attached to your arm. This fact means that 90% ...

Good while they lasted

Addam T., Newegg
23 October 2012
  • Summary: They friggen broke.
  • Pros: These come with a good assortment of tools to customize the fit to your ear. They fit comfortably and don't slip out.
  • Cons: Casing to one of the earphones broke within 3 months of very light use. I would not expect this from sport headphones. Volume control placement on the cord is very poorly designed. Should either be a bit lower or much higher. Weight of volume control can pull headphones out of ear if the wire isn...

User Review

Robert S., Newegg
19 September 2012
  • Summary: After all that, I have to say I will continue to buy products from both Newegg and Sennheiser, as I have enjoyed many 5 star purchases in the past.
  • Pros: I liked the idea of the fins and still do but the plastic seemed brittle around both ear buds and broke away in small pieces. So now I'm still using them along with another set I had purchased from Sennheiser via newegg that were also labled Sports, these were ones that formed around the ears and...
  • Cons: weak support material on ear pieces.

impressive sound for the money

randal c., Newegg
31 August 2012
  • Pros: This product has preformed as advertised. The ear buds stay put during biking, hiking and cutting the lawn. The frequency response is respectable and with a little tweaking of my iPod I was very pleased with the end result.
  • Cons: none so far !

Sennheiser Addidas Sport Earbuds

Christopher U., Newegg
15 August 2012
  • Summary: Overall I havent had these very long but from past experiences with other brands so far I am really happy with these Earbuds. The sound quality for the money is out of this world and the comfort as well.
  • Pros: Great sounding headphones, extremely comfortable in the ear. I really like the volume adjustment and the length of the overall wires. They are stylish, sound great and feel great in your ear, before you realize it you dont even know you have them in your ears.
  • Cons: Headphone jack/plug could be straight rather than a 45 degree angle or L shape. Otherwise nothing else that I can see thus far.

Good but not Great

Zachary G., Newegg
31 July 2012
  • Summary: All in all I was VERY impressed. I went into these thinking they would be mediocre. Sennheiser is a brand I trust, and that trust was not broken on this purchase. Would buy again, even if not for sport use. Better cord material would take this to a 5 egg review.
  • Pros: Sound quality is excellent. Better than I expected since I'm a bit of a bass head. Although they aren't the best IEM's I've heard, they do a good job at giving me the sound I want without hearing everything around me at the gym. They have many different fit selections making them very comfortable...
  • Cons: I would think that most vigorous runners would have a little problems with keeping these in. The cord is ample length, but that can also be a bit of a problem. The cord may be too much length for some. Also, the material that the cord is made out of isn't as nice of quality as I would like, but t...
