Review: First impression is good, works as advertised. - So, i bought the Momentum 3 battery for my Momentum 2 headphones. First off, it is shorter so i put a small piece of foam by it in the tray to hold it in place, secondly it is thicker, doesn't matter. The plug is the same and this battery has 30% greater capacity so I decided to go for it. I bought a correct one a while back but it never worked for charging so I tried again with this one. It indeed charges. Anyway, baring a rapid failure to hold a charge I consider this battery great. It has revived my 10+ year old headphones to working more than a couple hous a charge... I hope I get something comparable to when they were new or better. ## Features - Compatible with Sennheiser Momentum 2.0 HD 4.40 HD 4.50 450BT Urbanite XL Wireless Bluetooth Headphones Aerox 9 Aerox 5 mouse Battery Replacement。It can also be used in other 3.7-5V electronic products with power less than 2.4Wh (650mAh).（★ Not applicable to high-power electric tools and model aircraft） - Please compare the connector specifications and polarity according to the display diagram before purchasing,★the red wire is the positive "+" and the black wire is the negative "-"White wire is thermistor "NTC"，Do not reverse-charge or reverse-connectreverse. ★The primary battery of some products has no plug or mismatched plug or mismatched polarity.
