Discontinued Model
The Sony WI-C300 has been discontinued and replaced by the WI-C310. This is genuine, brand new stock - once it sells through, no further inventory will be available new.
The Sony WI-C300 Wireless In-Ear Headphones - Black is a behind-the-neck neckband wireless earphone - a form factor Sony has refined across multiple generations of its WI (Wireless In-ear) range. The neckband design distributes the weight of the battery, controls and Bluetooth module across the back of the neck rather than hanging all of it off the earbuds themselves, which is more comfortable for extended wear and reduces the cable tension on the ear tips. The 9mm neodymium drivers deliver Sony's characteristic clear, balanced sound - neodymium magnets produce a stronger magnetic field for a given size than ferrite magnets, allowing a more responsive voice coil and better control over cone motion across the frequency range. Bluetooth 4.2 provides a stable, low-latency wireless connection for music and calls. NFC one-touch pairing allows NFC-enabled Android phones to connect by touching the device to the N-mark on the headphones - bypassing the Bluetooth settings menu entirely. For non-NFC devices, standard Bluetooth pairing from the settings menu works as normal. Battery delivers 8 hours of continuous playback from a single Micro-USB charge - enough for a full commuting day without needing a top-up. The in-line remote provides playback control, volume and call management, and the microphone enables hands-free calling and voice assistant activation. Three silicone eartip sizes are included for a personalised in-ear seal. Genuine Sony. 1-year Sony warranty.
Bluetooth 4.2 + NFC
One-Touch Pairing - Stable Wireless
NFC (Near Field Communication) pairing eliminates the Bluetooth settings menu for compatible Android phones. The phone's NFC chip and the N-mark on the headphones exchange pairing credentials the moment they touch - the connection establishes and audio begins in under a second. Bluetooth 4.2 provides the underlying connection for audio once paired: a stable, low-power link with sufficient bandwidth for stereo audio at standard quality. The WI-C300 can be manually paired with up to eight devices and switches between them through the controls. Compatible with all Bluetooth audio devices including iPhone, Android, tablet, laptop and PC.
9mm Neodymium Drivers
Sony Sound Tuning - Dynamic Response
Neodymium magnets produce a stronger magnetic field than the ferrite magnets used in lower-specification drivers, resulting in faster, more responsive cone movement and better transient response. Sony's WI-series sound tuning emphasises clarity and balance rather than bass-heavy colouration, producing a profile that works well across music genres, podcasts and calls.
Behind-the-Neck Design
8h Battery - Comfortable for All-Day Wear
The behind-the-neck neckband positions the battery and electronics module at the back of the neck rather than in the earbuds or hanging from the cable. Up to 8 hours of battery life is sufficient for a full working day of commuting and use without recharging. Charging uses Micro-USB. Voice assistant activation from the in-line control gives hands-free access to Siri and Google Assistant without removing the phone from a pocket.
Great choice if you…
✔ Want a behind-the-neck neckband design that stays in place all day
✔ Have an NFC-enabled Android phone and want instant one-touch pairing
✔ Need 8 hours wireless battery for a full commuting and work day
✔ Want Sony's balanced audio tuning in a wireless in-ear design
✔ Prefer a neckband style over true wireless earbuds
Consider something else if…
✖ You want the current model - the WI-C310 is Sony's updated replacement
✖ You need Active Noise Cancellation - neither the C300 nor C310 has ANC
✖ You prefer truly wireless earbuds with no neckband cable
