Sony WI-C100 Wireless In-ear Headphones - Up to 25 hours of battery life - Water resistant- Built-in mic for phone calls - Voice Assistant compatible - Reliable Bluetooth® connection - Blue

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.

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.

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.
