Customers say
Customers find these wireless headphones offer good sound quality with brilliant noise cancellation and excellent value for money. The battery life is impressive, lasting forever, and they are comfortable, with one customer noting they can be worn under a motorcycle helmet. The Bluetooth connectivity receives mixed feedback – while some find it reliable, others report constant connection issues. Build quality and functionality also get mixed reviews, with some describing them as solid while others find them extremely weak, and some saying they work well while others report they only work about 50% of the time. Several customers report issues with the headphones falling out of their ears.

Simply the best wire(d)less headphones on the market
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.

Best Earphones I’ve Had.
I’ve had for 2 years now use them about 5 times a week average and still work great. The sound quality is impressive for listening to music, watch TV or audiobooks. The battery is still going strong. Typically use them an hour or so but some days I’ve used them for 5 hours+ and they don’t kill my ears like some styles. Used for exercising (neck band can be annoying if you’re “jumping” around) and general life. Good size and design fits in my pocket and the neck band stops me from losing them. Button panel is starting to go smooth but that’s it. Was a bargin at the time.

Excellent sound – a bit loose
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.

Absolutely useless
**EDIT** After using these for a few months now I absolutely hate them. There’s interference in the right headphone which has just gotten worse. And they have now started randomly turning themselves off whilst I am using them for no reason, even when at full battery. **I recently lost my headphones of 5 years, so had to buy a new pair. I was hesitant to buy Sony, as I once had a pair of over ear Bluetooth headphones that were AWFUL, but these has such good reviews I thought I’d give them a go. I wish I’d trusted my gut. The wire is too long, and the button panel and other thing are too heavy, which means they often get dragged backwards, pulling out the ear buds. Not to mention the incredibly annoying power on/off voice. I could deal with that, if it weren’t for the CONSTANT interruptions when on low battery. Just tell me once, and allow me to enjoy my music until either the battery dies, or I can charge them. As someone with ADHD, the constant ‘low battery, please charge’ fills me with instant rage. This seems to be a Sony thing, as the previous headphones I had did the same thing, so I’m definitely not buying Sony again.Pros: sound quality is good

Good in-ear headphones from Sony
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 arenât strong either. The noise cancellation is ok and the call quality is fine, too. They are ok to fit in ears and they didnât fall off while walking but not sure how good they can fit in whilst during the workouts. Have to try this though.

Great sound but wires too long
Sounds quality on these were really good for a small set of headphones. Returned as the wires are extremely long and not easy to manage in the gym. They also hang super low when around your neck too

Best bluetooth in-ear headphones I’ve tried so far with motorcycle helmet. Small footprint, does not stick out too much. Stays in place, both when putting the helmet on and off. Sound quality is good enough, considering the noisy environment. Normally I’m not a fan of extended bass, but a slight lift of lower frequencies is a welcome feature on the road. Noise isolation is medium. Engine noise is muted, but you’re not totally isolated from the traffic around you. I’ve NOT tried it as a communication device and cannot comment on the microphone quality. Battery time is excellent. Charging is done via standard USB C port. I wish they were IP rated. Good price/performance ratio (30 EUR). I would buy again.
