You already own the MOMENTUM 5 Wireless, so this is not a verdict on the headphones — that is the MOMENTUM 5 Wireless review. This page is about what its box list does and does not cover, and which accessories are worth buying on top.
Four picks, one job each: replacement ear cushions if the ones fitted wear out, silicone covers sold on extending their life, a second case Geekria positions as a replacement or upgrade, and an adapter for an in-flight entertainment jack.

What Sennheiser Packs, and What It Leaves Out#
Sennheiser publishes the contents in one line: one MOMENTUM 5 Wireless headphone, one carry case, one USB-C charging cable, one audio cable with 3.5 mm and 2.5 mm jacks, and documentation. That is the whole list.
Read it for what it leaves out. Sennheiser's box list names no airplane adapter and no spare earpads — checked 9 September 2026. One of those you want the day you fly; the other if the cushions wear out.
The Four Picks, and What Each Is For#
| What it is for | The pick | Buy |
|---|---|---|
| Worn ear cushions | WC PadZ replacement earpads | View on Amazon |
| Sweat and moisture on the pads | WC SweatZ silicone covers | View on Amazon |
| A replacement or upgrade case | Geekria Shield hard shell | View on Amazon |
| An in-flight entertainment jack | Cmple airplane audio adapter | View on Amazon |
The first three are about the hardware you already own; the fourth only earns its place if you fly.
If the Ear Cushions Wear Out#

Worn-out ear cushions can impair your headphones' sound performance. That is Wicked Cushions' own line, and it is the failure this pick answers.
These are sold for the Momentum 4, 5 and HDB 630, and the maker is blunt about the limit: "These pads are not compatible with any other headphone models." The cushion is high-quality PU Leather and dense memory foam, and fitting it is described as a quick, tool-free installation process with a video guide and an instruction manual — a job you do yourself.
The listing itself is not of one mind about that model list, and the caution is worth carrying: its bullets give the Momentum 4, 5 and HDB 630, while its Item details block carries a Compatible Headphone Models field naming one model, Sennheiser MOMENTUM 4 Wireless.
Keeping Sweat Off the Pads You Have#

Replacing cushions is the cure. The covers are the same maker's answer to needing that cure less often: silicone, custom-designed to fit Sennheiser Momentum 4 and 5 Wireless over-ear headphones, and they go over the pads already on the headphones. The routine is one line — "Slip them on and off your existing ear pads in seconds".
They are made from high-grade silicone, they are machine washable, and the whole pitch for them is extending the lifespan of your earpads by being exceptionally resistant to water and sweat. One qualifier belongs beside that: Sennheiser's own comparison table gives the MOMENTUM 5 Wireless a Water/Sweat Resistance row reading Not IP Rated. The covers are sold on protecting the earpads; the rating is Sennheiser's, for the headphones.
The covers listing is not of one mind about its model list either: its bullets name the Momentum 4 and 5, while its Item details block carries a Compatible Headphone Models field naming one model, Sennheiser MOMENTUM 4 Wireless.
If You Want a Second Case#

A carry case already ships in the box. Geekria sells its Shield as "A good replacement or upgrade for the original headphones case", and that is the honest frame for this pick.
In Geekria's own words its engineered hard shell protects against drops, impacts or crushes, and an internal mesh pocket "conveniently stores cable, cord, charger, AMP, earpads, adapter and other accessories". The Sennheiser entries in its compatibility list are MB 660 UC MS, PXC 550-II, Momentum 4 Wireless, Momentum 5 Wireless and ACCENTUM Wireless.
Plugging Into an Airline Jack#

Cmple gives the adapter's scope in one bullet: it "lets you connect your headphones to in-flight entertainment systems equipped with dual or single output 3.5 mm jacks". On the headphone end its claim is generic: "The universality of Airplane Audio Adapter allows you to use any headphones or earphones with 3.5 mm jack".
The wiring is the thing to get right, and the one covered here is the "Dual 3.5mm Mono Plug to 3.5mm Stereo Jack": two mono plugs on one side, one stereo socket on the other. Cmple's line for what that does is literal — "It converts 2 mono sounds to 1 stereo sound for your headphones" — and its product description says where those two mono sounds come from: "While most airplane audio system has two mono sound ports". Using it is one step: "Simply plug the headphones cord into the adapter and insert it into the airline jack".
Final Verdict#
Sennheiser's box list covers the carrying and the cabling but names no spare earpads, and Wicked Cushions says worn-out ear cushions can impair sound performance and that fitting a new pair is tool-free.
Buy the WC SweatZ covers if you sweat in these headphones: Wicked Cushions sells them on extending the lifespan of your earpads, and they slip on and off the pads already fitted — with the covers listing's own split model list in mind.
Buy the WC PadZ if the cushions on your pair have worn out — with the pads listing's own split model list in mind.
The Geekria Shield is a want, not a need: a carry case already ships, and Geekria positions its own as a replacement or an upgrade.
Skip the Cmple adapter unless you fly. Cmple's own line for what it does is "It converts 2 mono sounds to 1 stereo sound for your headphones".
Our recommendation: the covers if you sweat in these headphones, the pads if the cushions on your pair have worn out, the case if you want a second one, the adapter only if you fly — and read the MOMENTUM 5 Wireless review if you have not bought the headphones yet. View on Amazon
