Customer Reviews of Sennheiser MM 400 Stereo Bluetooth Headset (Black)
I have searched high and low for the right headphones that function properly and sound great, all within my budget. This is it! Sound is great, paired easily, functions well with my Galaxy S3 and is very comfortable. The only slight complaint I have is the awkward controls, which are not easy to find while on the head. I usually end up pressing the wrong button if I am not careful.

Great wireless Headphones8/31/2012
Sennheiser is world renowned for their sound quality, and these headphones are no exception. Had no problem linking to my iPod Touch. The sound quality is slightly Bass heavy (only slightly), the controls will take alittle getting used to, but overall, a great headphone and love the case that came with it.
This item is super awesome i had a pair and they sounded awesome perfect bass and everything :):):):)
Good Quality -6/26/2010
Very happy with the sound quality for Bluetooth and for the price. Purchased a refurbished unit for 1/3 the $300 retail. Not sure I would feel the same if I paid full price. Took a while to pair the first time. I have seen this model referred to as Noise Reduction if it is, its not by much, when music pauses you hear almost all background noise. Amazingly the battery lasts almost as long as advertised. Good buy for the money. The package did not include the USB charging cable, probably a packaging error and the carry case is not really a case, rather a zipper bag.
