Review: Brought my Sennheiser MOMENTUM 2.0 AEBT back to life. Forever greatful.
Review: 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.

長年使っているhd4.40btの充電ができなくなったので購入しました。 交換後、新品同様に充電が長持ちするようになりました。 購入を検討している方のために、下記書いておきます。 ・交換のために必要な工具はプラスのドライバーのみです。 ・端子類、配線は変える必要はありません。単純に既存の電池を置き換えるだけです。 ・電池交換のためにイヤーパッドを外す必要があります。ついでにイヤーパッドも交換してはいかがでしょうか。 おそらく、既に必要となった方がこの商品を見てるはずです。 ちゃんと使えるバッテリーですよ。おすすめ商品です。
