[2 Pack] easyBee Case Compatible with Sennheiser Momentum True Wireless 3/4 Bluetooth Headphone Charging Cover with 2 Keychain, Soft Liquid Silicone Ultra Thin Shockproof Protective Kit - Black Blue

It protects, there's nothing not to like.

I’m a journalist, and my Sennheiser Momentum 4 wireless earbuds are an essential tool during my workday. Before buying this case, I accidentally dropped them a couple of times, and my heart nearly stopped from the scare. Although the case seems a bit flimsy at first glance, I’ve found that it does the job. After several drops, my earbuds are still intact. It’s also helped keep them clean when I store them in my pocket or backpack. Definitely a good investment.

Just as thick as any other case

I wouldn't use earbuds without this awesome protective silicone case. Protects, waterproofs, helps alot if you drop it- but you shouldnt with the provided (very sturdy) clip..and you get 2 cases..best deal I have found. Too bad my momentum 3s came defective (from another seller) but I'll find another use for these awesome silicone covers. Highly recommend.
