I’ve been using the Sennheiser Momentum 4s for a bit now, and the sound quality is honestly the best I’ve had in this price range super clean with great bass that isn’t overdone. The battery life is insane, and they’re comfortable for long sessions, though the touch controls took me a minute to get used to. Overall, definitely happy I grabbed them.

I recently purchased a refurbished pair of headphones (excellent), and I am thoroughly impressed! The quality is exceptional, indistinguishable from a brand-new pair. The shipping was incredibly fast, and the packaging was secure and neat. Overall, a fantastic purchase experience. Highly recommended!

Great sound quality and very tight fitting. I recommend ready the guide online for common issue and how to overcome them

After 1 week they are working well, package received looked new in box and no evidence of previous wear/use.

Just a heads up, this item does not have a microphone built in. it is meant for listening to a TV or stereo system. The sound is amazing but with no mic as advertised is useless to me. Please fix the headline on the product so more people aren't deceived.

Yaaas! Received February and they still work flawlessly. Best decision to purchase from Backmarket. I can be rough on my electrics with my job and the they have been able to withstand my day to day ventures.

Great sounding headphones. I found them easily on BackMarket, the price was great and they came quickly. What’s not to like?

The headphones are fantastic and arrived in gently used condition.

I am seriously enjoying these headphones! It required a few days to acclimate/burn in, aided by an aftermarket cable upgrade. Very, very nice sound in a comfortable and lightweight product. Maybe better than my HD 580, although I don't have them in hand. They are an interesting phone to have along with HiFiMan Sundaras. Very happy to have not paid new list price!

Sound quality and noise cancelling far exceeded my expectations at this price point. They barely fit over my ears which is okay, at least they aren't crushing my ears. The microphone works decently. Battery life on them is great, I can get around 20 hours from them at my normal volume levels. However, the reporting of battery % is awful. It stays at 100% for what seems like hours then drops down to 60%. It originally would say, "low battery please charge" when it got low enough, now I just get "Power off" and they just poof. So instead of charging them when needed I am plugging them in every night so they don't die with no notice, last nights power off was reported at 60% since I had just checked the battery before they died, 10% when powered back on.
