Sony WI-C400 Wireless In-Ear Headphones – Great value for a solid product

I bought these to wear when i go cycling and walking so i needed to be able to hear the music and my environment. They’re comfortable to wear and due to it’s style doesn’t fall off when it’s not in use around your neck. Sound quality is quite good.

The sound is low apparently according to people on the other end of the phone which isn’t great, but at my end it sounds fine but they say i sound low. The music sound is very treblely. No good for the music i listen to. Useless on these earphones but if you can change the sound equaliser in your phone to sound better, then that’s great. They are probably best if you are listening to ‘talking’ via the headphones. People have said i sound louder in a call if i lift the left side of the neck band upto my face (mouth) so i presume the mic is in there. The buds feel secure in your ear.

These are chunky, but that is a natural consequence of a big battery. Very easy to link to my samsung s8. The neckband is comfortable on my solid 17′ neck. It is good for running but the neck is a bit too solid for squats when you settle on the bar but as i squat with the bar low, not a problem for me but if you rest the bar on your neck it would irritate. Battery life is epically good. Bluetooth range is extraordinary. Buttons feel nice and solid.

I was very sceptical when researching bluetooth headphones as i haven’t owned any before. Previously, i’d always spent between £5-£15 and been stuck with products that broke after a few weeks. Paying this much was a new experience for me, but i can confidently say that i am relievedthe setup process was literally 3 minutes, 2 of which were spent opening the package. First tried with a bassy nin track, i was very impressed. The controls are a doddle and the sound quality is pleasantly surprising for an in-ear headphone. If i had one (very trivial) criticism, it’s that i ordered the red ones and the colour is closer to a pink, but i have ovaries so it’s not a massive problem (cue flannel/snowflake gender related offence).

I hardly write reviews on my product i buy from amazon. But i couldn’t stop myself writing a review for this one. It’s a best earphone i have ever used. The sound is very decent, battery life is extremely good. It’s 3rd days on my usage and haven’t charged it yet. It was staraight out of the box. Noise cancellation is great too. And it is very robust device. You can throw it, rub it on sand , it’s build like a tank.

Reviews from purchasers :

  • Good for dancing.
  • Great buds
  • All day+ battery life, decent sound, great bluetooth buds.

Comfort: 4/5personally the neckband style of wireless headphones/earphones are not that comfortable for me, these are not that great either but that’s just a personal perspective on comfort. Sound: 4/5the sound quality isn’t that good if your an audiophile, but for general listening they are more than adequate. I have been spending about 8 hours a day wearing these and for audio books and podcasts the sound is as good if not better than sennheiser cx3. 00 which i had used for the previous 2 years. Battery life: 5/5battery life is where this excels. Due to working in a noisy factory i have the volume set at its highest, i get 2 full days before i charge them and even then it reports the battery level as medium so i would say that 20 hours at max volume is easily achievable. I have 2 very small sony mp3 players that have served me well for many years and that the battery technology sony uses in those is second to none which is why i opted to pay a bit more for a brand because i knew i’d get that better battery life. Connectivity: 5/5i have had minimal issues with connectivity. The sony wi c400 is paired with my one+5t and my acer r13 chromebook. The only issue i have is via the chromebook, the audio delay is about 0.

I use these headphones nearly everyday. From the morning commute to listening to music during the day and then a podcast/audiobook in the evening while out on the bike. The battery is reassuringly superb, often i’ll pick these up expecting them to be dead but the voice reports back ‘battery medium’ so i know i have another 8+ hours remaining. Audio quality is pretty good, controls are easy to use even with gloves once you learn the placement, very happy with these.

I listen to audiobooks in bed and my wireless beatsx were falling apart. I bought these and was so impressed, a few days later, bought another pair for my wife. She is every bit as happy with hers as i am with mine. Plus i was able to get a 2 year insurance on each.

I got not one but two faulty pairs. The first pair failed after about a month. The sound on the left bud suddenly dropped one day to about 10% of the volume of the right. Got them replaced for free by amazon straight away with no issue. Now 7 months later the replacement pair have also failed, again with the same issue of the left bud volume being a fraction of the right. Just happened last night out of the blue while i was washing the dishes. Very disappointing as i’ve really enjoyed my time with these earphone otherwise.

I quite literally use these 24 hours a day, with my portable charger i don’t have to take them off. The sound quality is fantastic, it’s sony, so of course it is. I can’t fault the sound quality. The battery life is very good, i’ve fallen asleep listening to music and woken up 9 hours later with them still on and then continued using them all the following day. I’ve used them whilst kickboxing sparring in the gym and the selection of earbuds allows me to select the best ones to fit my ear so they don’t fall out. If someone would’ve handed me a pair of these to use for a couple days and told me they cost twice the price i wouldn’t complain. These earphones are fantastic.

I love those little headphones, absolutely comfortable and light weight, after a couple of time that i wear them i got so accustom to them that now after 2 weeks is like they are not there,apart when my phone is ringing and the headphone vibrate so handy, never miss a phone call again. Audio qualtity is superb, what one expect form sony after all, so far i naver have a problem with battery. Battery level can be easly checked by pressing power botton and voice will tell you the level. Is possible to controll siri and alexa and google. Can spell out song title to alexa on amazon music without touching phone. Resistant to rain, i have been using them outdoor with rain dropping on them no problem at all. My only wish was that the cable lenght cuold be ancored to the lenght i prefer, even at full lenght cable are not in the way so i guess it doesn’t it works anyway.

Awesome quality, good resistance to water and sweat. Bought these for my job as i’m a cage dancer in an industrial club but i like to listen to celine dion when i’m swinging my booty. They regularly get drenched in sweat and glitter and are still pouring sweet high notes in my ears till the small hours of the morning.

They fit nicely in my ears and also under my 3m peltor ear defenders without causing any discomfort. The battery does last long i used it for 2 full days of music at work 16 hours total and the battery level was ‘medium’.

I like the fact that they vibrate if a call is coming in. I bought to use whilst running in the gym and they don’t slip out which is faboutside sound is muffled hence 4 stars. Sound quality is good but a bit more to the bass would have been better. For the price though,they are a good buy.

Great headphones – good sound quality, great battery life. Neck band is a bit clunky, but that’s what gets you the batter life. Also it stops the headphones being lopsided or pulling out of one ear like you get on a lot of bluetooth headphones.

The sound quality of these ear buds is amazing. I have had quite a few other bluetooth headsets. Some work but the sound quality is diabolical. These reproduce the sound of the bands i love brilliantly. As i really love heavy metal the bass is quite heavy and these buds cope very well. The supplied rubber buds are really good at keeping the ingress of out side noise out. Comfortable, light and connects very easily. I would highly recommend these to anyone who likes listening to music of any kind.

I bought this on a whim seeing the price was reduced and battery life was rated high. I have used this type of bluetooth head set for a few years and oh how i wish i had come across these sonys’ before. I cant afford the top of range headsets but i doubt they would be any better. Controls are easy and intuative, the voice warning for on / off hi lo mid battery level is clear i am more than happy. Only niggle is each cable comes out the inside then slots through to the outside and is very thin but 6months continuous use (wife complains im never without them) as im retired, and still performing well.

I got these headphones for working out in the gym, but because they are wireless and very very comfortable with a good battery life, then i actually ended up using them all day everyday. Delivery was fast, so i was impressed, even though i didn’t pay for expedited delivery it felt like it was just that. Sound quality is good, i prepared myself for lesser base etc which i normally prefer when in gym, but given that these are in-ear and wireless i had to lower my expectations for the sound quality, but now it turns out the quality is better than expected. I don’t mind that they do not cancel out all the outside noise, not sure if that was a thing it’s supposed to do. Battery life is as promised, but i guess you also need to charge it up to 100% and not somewhere between 0 and 100. Plus it always is a good idea with gadgets like this to have it run completely to 0% where it says ‘battery low’ or ‘charge battery’ etc. Buttons on the neckband are a bit hard for me to get used to so i still use my phone to adjust volume. All in all great product for this price.

The sound is pretty good and you get decent bass as well. The battery life is incredible, you can go a couple of days without recharging no problem. They’re comfortable for long use, and you can sort of hide the collar under your own collar or shirt. So even when you’re not using them you can just keep them on your neck. I use them for exercising as well, but keep in mind they’re not sweat-proof or waterproof, so only light exercise. Downsides:since the battery life is so long, if you run out of battery it will take a good couple of hours to recharge.

This works but it has quirks that could be annoying. For example it turns itself off occasionally or disconnects. You need to learn about the reset button(s). It is very comfortable to wear and i use it all the time so it can’t be that annoying.

The headphone fits me very well for its high sound quality , battery durability, and the motion design. But without the magnets in the buds so they swing when not used. After i checked the catalogue of the sony products, another version owns the function, and costs much more. In a word , it was worth of every penny.

One Response to Sony WI-C400 Wireless In-Ear Headphones – Great value for a solid product

  1. 1.0 out of 5 stars Randomly just wont turn on or even charge says:
    Overall, i’m not happy with these. The battery life and sound quality are both exceptional but i’ve bought 2 pairs of these in the last year and both have just stopped working. They wont turn on, they wont charge. The first time i thought maybe i had done something to damage them so was very careful with the 2nd pair but the exact same thing has happened again.

      I liked the way the headphones worked and especially the battery life. I didn’t like the fact that after a run the headphones failed due to ‘water’ ingress. I finished exercising and they were still working, after a while they started to vibrate (as if someone was calling me) and that was it. Tempted to buy another pair but i won’t use them in the gym.

      Awful quality both build wise and sound. For £40 sony headphones they are cheap and plasticky and just terrible feeling. I got these as a replacement for £25 jabra headphones and the difference was gobsmacking, jabra faaaarrrrr superior in every way, except the ear piece didn’t fit my ear 😀 these are too quiet as well, i could easily my tv at normal operating volume over them when on full volume, hence sound quality was awful. Just don’t waste your money, there are far better options out there at this price and even cheaper.

    This review is from : Sony WI-C400 Wireless In-Ear Headphones with up to 30 Hours Battery Life – Red

    I love this headphones because of its lightness and battery life. However i found it a little unstable staying in place around my neck, especially when you have to rest them around clothes. The workaround i have is to ensure they sit directly on my neck under my collars, but that isn’t always convenient. The neckband needs to be made more firmer and stable.
