Sony WI-C100 Headphones 
Packed with features
The WI-C100 wireless in-ear headphones offer great value, with a wealth of features including long battery life, high-quality sound, splash-proof design, and compatibility with the Sony | Headphones Connect app.
Long battery life of up to 25 hours
Enjoy up to 25 hours of non-stop music. And if your headphones are running low on power, a 10 minute quick charge will give you up to 60 minutes of playback.
Sound Quality 
Make your music sound more natural
When an original music source is compressed, it loses the high-frequency elements that add detail and richness to a track. Our Digital Sound Enhancement Engine (DSEE) restores them to produce high-quality sound that’s closer to the original recording.
Well-balanced tuning
Tuning is well-balanced from low to high frequencies, and vocals are natural and clear. So the WI-C100 headphones match any music genre.
Easy to Use 
Splashes and sweat, no problem
With an IPX4 water resistance rating, splashes and sweat won’t stop these headphones – so you can keep on moving to the music.
Stable wireless connectivity
Say goodbye to tangled wires – with Bluetooth wireless technology, connect to your device wirelessly and enjoy stable, uninterrupted listening.
Clear hands-free call quality
Conversation flows freely with clear hands-free calls thanks to our high-quality built-in microphone. No need to take your phone out your pocket.
Easy operation with buttons
The WI-C100 headphones are easy to operate, with buttons to play and pause, skip tracks and adjust the volume, as well as receive calls.
Fast Pair
Find your headphones easily with Fast Pair
Fast Pair makes it easy to pair your headphones with your Android devices. In one tap of pop-up guidance, the WI-C100 headphones enable quick, effortless Bluetooth pairing with your Android devices. Also, you can easily locate where you left your headphones by ringing them or checking their last known location on your smartphone.
Voice Assistant compatible
One simple button press connects you to your smartphone’s voice assistant so you can find directions, play music, & communicate with contacts.
Sustainability in mind
Plastic comprises less than five per cent of the individual packaging material for the WI-C100 headphones.
Connect easily with Swift Pair
Swift Pair makes it quick and easy to pair your WI-C100 headphones with your Windows 11 and Windows 10 computer via Bluetooth.

Customers say
Customers find these wireless headphones offer decent sound quality with extended bass and good battery life that lasts all day long. The build quality is excellent, and they receive positive feedback for their overall performance and value for money. However, functionality and ease of use receive mixed reviews – while some find them easy to use and connect, others report issues with connectivity and the mic stopping working within a month. The charging cable is also a point of contention, with some praising quick charging while others note the lack of included cable.

Great value headphones with amazing endurance.
This is a great value around-the-neck headphones. The claimed battery is 24 hours which sounds about right as after using them for a 15+ hour session, they had not yet hit the 30% warning. They are comfortable with three different sized tips to fit whatever sized ear holes you might have.The only negative I can say is that compared to the other headphones in this model family, it does not have a magnet in one of the earbuds for pairing around your neck when not in use. I solved this by hot-gluing a magnet to one of my earbuds, but it’s annoying that I have to do it myself. Come on Sony! It’s like a 10-cent part.Bluetooth connectivity is strong and I can mostly listen to my tablet from the otherside of the house (walls permitting).Sound quality is perfectly acceptable for me. It’s only standard A2DP so there’s a cap on the maximum quality you’re likely to get anyway.

Comfortable
The Sony WI-C100 wireless in-ear headphones have truly impressed me with their blend of affordability and reliable performance. If you’re looking for a solid pair of everyday earbuds that won’t break the bank, these are definitely worth considering.One of the standout features is undoubtedly the incredible battery life. Sony claims up to 25 hours, and in my testing, they’ve consistently come very close to that. This is a huge plus for anyone who’s tired of constantly charging their headphones. I’ve used them for several days of commuting, workouts, and calls without needing to plug them in. This longevity makes them perfect for travel or long workdays.The water resistance is another welcome addition. While I haven’t submerged them, they’ve held up perfectly fine during sweaty gym sessions and a few unexpected light rain showers. This gives peace of mind knowing they can handle the rigors of daily life.The built-in microphone performs admirably for phone calls. Callers have reported clear audio on my end, and I’ve had no trouble hearing them. The convenience of being able to take calls without reaching for my phone is a significant advantage.Voice Assistant compatibility is a nice touch. I’ve easily been able to activate Google Assistant with a long press of a button, allowing for hands-free control of music, calls, and information. This integration feels seamless and intuitive.The reliable Bluetooth® connection has been a consistent positive. Pairing was straightforward, and I’ve experienced minimal dropouts or interruptions, even in crowded areas. This stable connection ensures a smooth and enjoyable listening experience.In terms of comfort, the WI-C100 are lightweight and come with different sized ear tips, allowing for a secure and comfortable fit for various ear shapes. I’ve worn them for extended periods without any significant discomfort.The sound quality is perfectly acceptable for the price point. While they might not satisfy audiophiles looking for the most nuanced and detailed sound, they provide a balanced audio profile that’s enjoyable for everyday listening to music, podcasts, and audiobooks. The bass is present without being overwhelming, and the mids and highs are clear enough for a pleasant listening experience.Design-wise, the black finish is sleek and understated. The neckband design is practical, allowing the earbuds to rest comfortably around your neck when not in use, preventing them from getting lost. The controls are easily accessible on the neckband, allowing for convenient volume adjustment, playback control, and call management.Overall, the Sony WI-C100 wireless in-ear headphones offer an excellent combination of long battery life, water resistance, reliable connectivity, and convenient features at a very competitive price. While they might not have all the bells and whistles of more premium options, they deliver on the essentials and provide a solid and dependable wireless audio experience for everyday use. If you’re looking for a budget-friendly pair of wireless earbuds that simply work and last, the Sony WI-C100 are a fantastic choice.

Cheap, all-day sound for poor sleepers/travellers (misophonia and/or Asperger’s/autism).
The battery life makes this really good for sleeping in, or wearing for extended periods, without needing to recharge at all during the use period (no docking to get the extra promised hours of individual buds, you *will* get a full night’s sleep with this).It’s as comfortable to wear as regular wired buds, though the weight of the battery and transmitter pieces on the wire will make it want to tug out of your ears when you toss and turn, or walk around.Sound quality isn’t super amazing out of the box, compared to the equivalent budget wired Sony earbuds (like MDR-EX15AP, which I recommend as a budget wired option, and you can use a cheap extender cable if needed), but it’s more than sufficient for casual use, and especially sleeping whilst wearing. You can adjust the output with EQ software.The microphone is pretty clear, just be aware of fabric rubbing like any wired earphones, and just try it and see how you like it. I don’t use this thing for calls, personally.I find this cheaper Bluetooth version WI-C100 better than the more expensive WI-C200 version. Barely any difference in functionality, this maybe even being the superior product, but this is cheaper.I easily get 16h+ out of these, plenty for a night’s sleep, and time before and after that. Essential for me with sensitivity to neighbour noises, and needing sound to sleep. Whilst I only bought this because my new phone didn’t have an AUX input, and the adaptors didn’t work for my newer phone, it really is much more convenient.If you expect to wear this for 16h+ per night/day, you might want a second one to keep in a drawer/your bag, in case you wear out the battery before being able to recharge, which only takes maybe a couple of hours, and doesn’t need an expensive wall charger. It comes with a USB-C port for charging.The 25h claim is overly optimistic (I assume this is done with the bare minimum volume and functionality). I would say maybe 18h would be the most to expect.Really, I can recommend these as a budget sleep-aid for us bad sleepers, especially those with misophonia and/or Asperger’s (you can combine this with brown noise on your phone/computer to provide external noise masking, as there is no ANC (active noise cancellation) with these).Also, as just a cheap pair of Bluetooth earphones that can cope with sweat, it’s still good option for all-day use, with adequate sound quality after you adjust the EQ to your liking.Note: These will automatically turn off when the USB-C is connected to power or a device, so cannot be used whilst charging, or as wired earphones. Damned companies removing useful 3.5mm ports.

Maybe not the best quality sound but it’s the easiest a d the most comfy one to bring on with me and not lose it. I bring it with me everywhere, it’s lightweight and I am not obligated to hear all my colleagues in the open space and just chill to my music.
