Assessment scenario: Earlier sealed no-ANC earbuds with IPX4 buds and wired case
An editorial scenario for an earlier sealed in-ear configuration without ANC, with the exact IPX4-headset-only boundary and a USB-C case confirmed to lack wireless charging. This describes published model facts, not a visitor’s intent, personal fit, present offer or older-battery condition.
Explore this buying guide ↗Why consider this model?
- Sony’s model guide describes a closed, tip-equipped design with SS/S/M/L hybrid tips and twist-to-seat instructions. That documents adjustable geometry, not an individual’s seal or comfort.
- Sony explicitly says the WF-XB700 does not support noise cancelling, so it fits this no-ANC scenario rather than an ANC request.
- The model guide assigns IPX4 to the headset only and states that the case is not water resistant. Sony documents USB-C case charging; SonyListens confirms this exact case lacks wireless charging.
- Sony lists separate maximum nine-hour SBC and AAC music plans and a 9+9 hour case total. These are maker maxima under conditions, not a measured result or estimate of an older battery.
Tradeoffs to weigh
- This is an earlier model; Best Buy said the exact Black item was no longer available new on the checked date. No present offer, used condition, warranty, price or seller package is asserted.
- The 9-hour numbers are music playback maxima, not ANC runtime; the model has no active ANC. Battery health and runtime of any aged unit are unknown.
- Sony warns that the case is not water resistant and the headset is not for use underwater. IPX4 is not swimming or immersion protection.
- Sony says up to eight devices can be remembered but only one can transmit/play at once; multipoint is unsupported. The manual’s original accessory list does not establish the contents of a particular older sale.
Check these before ordering
- Confirm exact Black U.S. suffix WFXB700/B and item 6408362; Blue WFXB700/L is a separately recorded finish, not the Black seller’s box.
- Ask the seller to verify both earbuds pair and charge in the matching case, and inspect USB-C charging, battery behavior, and return terms. Do not treat nine-hour published maxima as proof of an old battery’s health.
- Check whether the short USB-A-to-USB-C cable and SS/S/M/L tips are actually included; original package documentation is not evidence about a used listing.
- Keep the case dry, wipe moisture from the charging port before charging and do not use the earbuds underwater.
