Assessment scenario: Sennheiser SPORT True Wireless, U.S. article 509299, is an earlier sealed in-ear model with no active ANC and IP54 protection on the earbuds only. Its charging case is USB-C and must stay dry; the available evidence does not establish whether it also supports wireless charging. This does not prove seller stock, battery health, package contents or the visitor’s intent.

Assessment scenario: Earlier sealed in-ear, no-ANC listening with IP54 earbuds
Assessment scenario for the Sennheiser SPORT True Wireless U.S. article 509299: an earlier sealed in-ear model without ANC, with IP54-rated earbuds and a case that must stay dry. Its open/closed adapters are still in-canal. Wireless case charging is not established. This is not the visitor’s actual intent or evidence of a complete or current seller offer.
Explore this buying guide ↗Why consider this model?
- The exact U.S. product data identifies article 509299 as one Default Title configuration; Sennheiser marks the product end of life on its U.S. site. The original observed model is therefore assessed as earlier, without implying current third-party availability.
- The exact manual calls the design true-wireless earbuds with ear-canal coupling. Open and closed adapters change the Aware/Focus acoustic setup but remain in-canal attachments; they do not make this an open-ear model. The manual’s fit sizes cannot guarantee personal comfort, seal or workout retention.
- The model specification explicitly says active noise cancellation is false. Focus is not ANC. The product’s nine-hour AAC example is ordinary music under stated conditions, not ANC-on runtime.
- The model manual rates the earbuds IP54 and explicitly says the charging case is not splash-proof and must stay dry. The water digit 4 supports the finder’s IPX4-level buds-only option; it does not rate the case or permit immersion.
Tradeoffs to weigh
- Sennheiser’s end-of-life notice concerns its U.S. web store. No third-party seller, current stock, condition, price, warranty, return terms or battery health was checked.
- The manual documents USB-C case charging, but the sources checked do not establish whether the case also supports wireless charging; it is not counted as a strict wired-only match.
- Two simultaneous Bluetooth source-device connections are not established. A source-selection function or remembered pairing would not prove multipoint.
- The exact gallery image depicts the black earbuds alone. It does not prove the case, adapter sets, fins, cable, package completeness or operation of any seller unit.
Check these before ordering
- Verify the exact SPORT True Wireless article 509299 and that both earbuds pair with the matching CX200TW1 C charging case; do not conflate it with CX SPORT article 508256 or the later MOMENTUM Sport.
- Ask which pieces are included: the manual’s original list includes open and closed S/M/L adapters, fin sizes N/S1/S2/S3, a USB-A-to-USB-C cable and the case. The manual list does not establish the contents of a resale offer.
- Demonstrate charging and playback for the actual older battery, check app pairing and the correct adapter/mode, and confirm the seller’s condition, warranty and return terms.
- Keep the case dry; do not shower, swim or immerse the earbuds, and dry wet earbuds fully before charging. Check current host/app compatibility if relying on Aware/Focus or EQ settings.
- If wireless charging or a guaranteed USB-C-only case is essential, request exact-case manufacturer evidence rather than inferring either answer from the USB-C port.
