**Q: Why doesnt mine turn on for hours after charging?   anyone else had issues with it not turning on after charging for quite some time?**
A: Hi Mart,

We're sorry to hear this! Charging is supposed to be completed in about 3 hours and the red indicator turns off automatically as clarified here: https://cutt.ly/bFvWdBC, and you are able to turn on the Headphones normally. If this is not the case, try resetting and initializing the Headphones by following the steps described here: https://cutt.ly/2FvEaAQ & https://cutt.ly/xFvEgdI as an attempt of rectifying the issue.

### ⭐⭐⭐⭐⭐ Simply the best wire(d)less headphones on the market
*by O***N on 31 March 2024*

I've recently moved to flagship true wireless WF 1000XM5s for the incredible sound quality. I miss the WB-XB400 which are otherwise vastly superior in comfort, convenience, battery longevity, affordability, and usability (no extra app needed).17+ hours battery life IN USE, easy. I charged them every 4 days and used them for my 1h commute (back and then forth), whilst at work for music, calls and meetings, and then at home too. Sound quality is really very strong, crisp with a surprisingly good bass. Cannot overstate this point - no headphones at this price point compare, and I have also owned headphones twice the price which cannot touch them sound-wise either. They sit comfortably around your neck when not in use and the battery/volume control widgets balance it nicely without feeling weighty; like, you know they are there so you're not gonna lose them, but they're no burden. That they are USB-C is seemingly standard but beware buying other headphones at this price point where you might end up with a USB 2.0. They reach a 50% charge in about 15 minutes. They come with a variety of plug sizes and a short-lead charging cable.I've owned 3 pairs. I had to replace one pair after a year and a half, lost another, and gifted the other when I finally upgraded.Main cons - The flap that opens to allow you to charge it will eventually stop closing flush after around 6 months. It's not fixable as it happens because the housing for the plastic catch wears out; your options are to deal with it (it kinda half-closes in a dissatisfying sticky kind of way) or remove the flap entirely. Also, the sleeve of the earplugs (like the rubber underneath the headphones themselves) will start to tear and come loose after about a year. The headphones themselves stay connected but you end up with this tube of rubber sliding down from the headphones and sitting on the battery/control packs. Neither affect the usage or sound quality - anyway, at this price (and after that long) I am sure you'll basically just replace them with the same set, as I did for a good three years.If I was asked which are overall the best headphones on the market to this day, I'd recommend these.

### ⭐⭐⭐⭐⭐ Good in-ear headphones from Sony
*by A***N on 27 November 2021*

I recently bought this one from Sony and I really loved it. It is way better than my beatsx in which the right side stopped working after six months, and it was the one that I got it as a replacement after I had the same issue with the previous one. The bass quality is really good and is of Sony standard and with this price it does a fair job and is definitely way better than my Beatsx and the cheaper options. The ear buds are soft and they fit in ears very well. I liked the recorded voice over notifying power off and on options as well bluetooth connectivity. This is useful as I always struggled with my Beatsx and I had to double check manually to know whether or not it is turned on or off and get connected or not with my iPhone. The battery charges fast and the power stays for a day for me as I only use this to make some calls and hear songs at random times. I found the only downside with this one is their cables are bit longer than normal and the magnets are slightly off, so you have to twist the ear prices at a certain angle to clip them together, the magnets aren’t strong either. The noise cancellation is ok and the call quality is fine, too. They are ok to fit in ears and they didn’t fall off while walking but not sure how good they can fit in whilst during the workouts. Have to try this though.

### ⭐⭐⭐⭐ Excellent sound - a bit loose
*by P***G on 10 May 2025*

I patiently tried to use the most appropriate of the 3 different ear pieces and also located them properly but they are not perfect. They stay in if you're not moving but walking or jogging you find you are just pushing the left ear back in every five minutes. It may well be that the volume and battery block is locate on the left and the weight of this drags that ear piece down a bit.But the sound - for this price - is excellent, the bass boost is the right frequency it's not to muddy or boomy, you just get a better low-end boost.So for the sound, price and overall build quality a worthwhile purchase.
