Review: 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.
Review: Every bit as good as they claim to be - Finding myself now using my phone for playing music more than in the past, and then finding the USB-C headphone adapter more of an annoyance than it was when I only used it occasionally, I decided it was finally time to get some bluetooth headphones... My first choice would have been Sennheiser, having been a fan of their wired sets for the past couple of decades, but the ones I had my eye on weren't available, so I started to look elsewhere for something that might be a suitable alternative in the meantime. My criteria were fairly straighforward - I wanted plain earbuds, decent battery life, easy recharging (i.e. direct USB connection, not via a charging case), and for the two buds to be connected so I could take them out and leave them hanging round my neck just as with wired buds. After a bit of searching, I'd narrowed down my list to either these or the similar C310, and as I've already got a few USB-C cables, the latter coming with a cable of its own wasn't enough to swing me towards that model given the 9 hour shorter rated runtime compared with the C100. Having now been using them for just under a week, I'm pleased to say these buds live up to their billing - as comfortable to wear for extended periods as my favoured Sennheiser buds, even with the extra weight of the control unit and battery resting against the sides of my neck. Sound quality is impressive given they're relying on their internal amplifier rather than being driven directly from the phone or laptop, and at full volume they pack a surprising punch. Perhaps not quite as bass-heavy as the Sennheisers, but still full bodied enough to put a smile on my face when the drums or bass guitars kick in. I haven't yet given the battery a full stress test, however after around 8 hours of use from full charge the reported charge level had dropped by 30%, which bodes well for them achieving the stated runtime. And recharging from the USB-C connection is easy and quick, so between the long runtime and fast recharge times its unlikely I'll find myself wanting to use them but being thwarted by a low battery warning. One thing I wasn't expecting from them was to be able to use them as a headset in Teams calls - I knew they had a microphone and could be used as a headset with a phone, but from what I've heard about other headsets it's not a given that they'll also work on a PC in that way, so this was a pleasant surprise. And whilst the audio quality here isn't quite as good as a dedicated headset with boom mic, it's easily good enough unless there's a lot of background noise - being able to switch instantly from listening to music to being in a call, without having to swap from headphones to headset and vice versa (as noted above, the C100's aren't quite as good as my headset for voice calls, but they're SO much better for music). Plus being wireless means I'm no longer tethered to the PC via the USB cable... On that note, with the PC in my upstairs office, I can walk around almost all of the house without dropping the connection - it's only once I walk into the extension out the back of the house that the signal cuts out, so the claimed 10m range doesn't seem unreasonable. Pairing the buds is about as easy as it gets with bluetooth gear these days - press and hold the power button until you hear them say they're in pairing mode, then select them from the list of available devices on whichever thing you're pairing them with. So far I've paired them with my phone and two laptops, and switching from one to the other takes just a few seconds, accompanied by another verbal indication of connection success. They're definitely a no frills set of buds - aside from the buds themselves, the only other thing in the small box aside from the instructions is a set of alternative earpieces in differing sizes, as is the norm with bud-style units. No USB cable or storage pouch or anything else like that, but what that means is that you're paying for the buds and nothing more, and that shows in the performance you get from them for your money. And I have to admit to being genuinely impressed with them, to the point where I'm starting to wonder if I'll bother replacing them with the Sennheisers I originally was after.

### ⭐ Review
*by H***Y on 16 July 2024*

3 months of light use and one side is completely broken and the other is muffled. Do not bother with these! I had an older version of these that lasted for years. Clearly Sony can no longer make a quality headphone.
