Rated 5 out of 5 by from Clear sound, good for piercings [This review was collected as part of a promotion.] I've been using these headphones for a few weeks now. They have a nice sound, c which is what anyone is looking for in headphones, but what I like most is how well they fit with my unique ear piercings. I have rook piercing, which doesn't usually create too many issues with headphones, and a daith piercing, which creates a LOT of fit issues. These headphones for nicely on my ears and around my piercings creating a good sound vacuum. I like the sound and that they block outside sound a bit as well. Overall pretty happy with them.

Rated 4 out of 5 by from Decent sound [This review was collected as part of a promotion.] These headphones have good sound quality and are good for listening to an audiobook. They are wireless, but there is still a wire that goes between the two earbuds. It took 3 hours to charge and set up for first time use. Also, the large size earbuds were too big for me and kept talking out of my ears. I’ll a 40+ year old woman, and I needed the smaller size.

Rated 5 out of 5 by from Great sound! [This review was collected as part of a promotion.] These are some if the best wireless headphones I've had. Easy to charge, comfortable and easy to wear and fit anywhere to store ready to go. Can tell they are very durable and will work for a long time. But only time will tell.

Rated 4 out of 5 by from Great value [This review was collected as part of a promotion.] The Sony WI-XB400 bluetooth headset is a great value but fall short in a few areas. First, the sound quality of these bluetooth headphones is excellent. Good amount of bass with just the right amount of mids/highs to complement the lows. Call quality is good and no problems there. The battery life is really good as well. I have been able to get the 12 hour battery life and then some with every charge. Easy to pair and very straight forward instructions in the box. I was actually impressed by how straight forward the instructions were. Now for where they fall short. The magnet that snaps the earbuds together is fairly weak. When not using the ear buds, they tend to come apart easily. Furthermore, these are the longest headphones I have ever seen. I understand the thought is to cross them when putting them in your ears. However, I just cannot get used to this after using other shorter headsets. Overall, a great value and really good quality bluetooth headset if you can get used to the length and cross the cables when wearing them.

Rated 5 out of 5 by from Great earbuds [This review was collected as part of a promotion.] I got these for my husband to make it easier for him to listen to music at his job and he loves them. The sound is great, they last a long time between charges and if he calls me while he's using them we can both hear each other well. I definitely thing they're a good purchase.

Rated 3 out of 5 by from Just Okay. [This review was collected as part of a promotion.] I've been using these for a few weeks and don't love them. It took me a bit of time to figure out how to get them to sync with my phone. Once I figured it out, I still am not super impressed with the sound quality.

Rated 4 out of 5 by from Amazing quality [This review was collected as part of a promotion.] I use these when i'm doing my household chores and love the quality. The sound is amazing and they block out any background noise. I have 3 rowdy boys who fight all day but not when I have these on, I can't hear them. And yes I make sure there is another adult around to make sure they are ok. I love how sleek they look and how easy they are to use. Only thing I don't like is that they hurt after a while. My ears are on the smaller side so i've always had that issue with headphones. Best part is they are WIRELESS! I don't have to worry about carrying my phone around with me or getting tangled while i'm trying to move around. Perfect for my hectic lifestyle.

Rated 5 out of 5 by from Favorite wireless headphones [This review was collected as part of a promotion.] These work exactly as you expect them to. Fantastic sound, long battery life (I work out for 45 mins/day Tues-Thurs) and don't have to charge these for a couple weeks. In comparison to other high end wireless headphones I splurged on several months ago (made by your favorite search engine company), these stay connected 100% of the time, sound even better, and have a longer battery life. Really wish I'd have saved my money on the other earphones and just gotten these to begin with. Highly recommend!

Rated 4 out of 5 by from Crisp and long lasting [This review was collected as part of a promotion.] For voice communications these are great. The sound is crisp and clear, but several people I tried to communicate with complained the mic pickup was weak. I wasn't impressed with the music quality, though it was crisp and clear. I don't think there is nearly enough bass. I think some of the music quality issue is due to the design of the earpiece will not allow for the earbud to really fit very far into the ear canal, regardless of which pads are used. I got them primarily for voice listening as in talk radio over the internet and such, and so they work fine for that. Pros: superb battery life, lasting from 20-24 hours of almost continuous use, and much longer if used extensively on standby. Comfortable to wear in a normal manner. Good voice quality, crisp and clear. The magnetic backs cut down on tangle and cut down on "dangle-tangle". Cons: Only average music quality (too crisp and "tinny" sounding, with lack of bass for my taste). Comfortable to wear but not to sleep in, as the buds extend too far outward and pillow pressure on them creates an uncomfortable fit. Back sleepers would have no issues. Overall they appear to be a well-made set of general-purpose Bluetooth buds with exceptionally good battery life.

Rated 5 out of 5 by from Work great! [This review was collected as part of a promotion.] These war buds are awesome! The base is amazing and even though not labeled as noise canceling they really do seem to be. They are comfortable to wear and didn’t ever feel like they were going to fall out. They wrap around your neck to stay in place which I absolutely prefer. They have magnets to keep from falling off when not in use. Charge with type c which is an added perk. They connected via Bluetooth easily and quickly. Came with different sizes for the ear pieces. Love these

Rated 5 out of 5 by from Good earbuds! [This review was collected as part of a promotion.] These are good earbuds with good features. First off, the extra bass is present. Initially, I didn’t like the overall sound of the music, but after playing with the equalizer settings a bit, I’ve gotten to a sound that I like. I like the audible, “power on” battery percentage reading, and “power off.” I found out, accidentally, that earbuds have magnets in them so they stick together when they’re on my neck, but not in my ears. I’m really happy with these earbuds.

Rated 5 out of 5 by from Love these [This review was collected as part of a promotion.] I am always looking for a good pair of headphones for the gym. I need something that will stay in place, sound good and be durable. I’ve been using these a few weeks now and I love them. I highly recommend getting a pair.

Rated 5 out of 5 by from Awesome sound [This review was collected as part of a promotion.] I purchased this product about a week ago. When I purchased it, the quality of how it was made really attracted me to it. Plugged it into my radio and I could not believe how amazing these headphones sounded. I never leave home without them being in my bag

Rated 4 out of 5 by from Works great [This review was collected as part of a promotion.] The Sony - WI-XB400 EXTRA BASS™ Wireless In-ear Headphones works great and has a great sound.

Rated 5 out of 5 by from Awesome Sound! [This review was collected as part of a promotion.] I love my new Sony Wireless in-Ear headphones. When I am working from home, I usually have to keep my headset/headphones on all day long to answer phone calls or jump on an impromptu video conference call. With my Sony WI-XB400 headphones, that is no problem. They are extremely comfortable, phone calls are super clear, and they have an amazing battery life. Normally I charge them at night, but I have gone several days between charging without any issues. When I am not working, I use these to listen to music and podcasts. The Extra Bass makes my music sound great. They also do a good job of blocking out the noise from my surroundings. When I am not using them, the magnetic earbuds keep them secure around my neck.

Rated 5 out of 5 by from Sleek & lightweight ear buds [This review was collected as part of a promotion.] I like how sleek & lightweight these Sony WI-XB400 Extra Bass Wireless In-ear Headphones are. They’re well-made and comfortable to wear with soft & removable silicone cover ear buds. They are wireless, so there are no cords in the way, they just sit around the neck and the two ear buds snap together with a magnet when they’re not being used. They are great for on the go and commuting for hands free phone calls. The microphone and volume control buttons are big, so they’re easy to handle without looking at them. They have good sound quality. The sound is clear and has good bass to them. They connect via Bluetooth and charge quickly via USB cable which is provided with the headphones.

Rated 5 out of 5 by from Great Product [This review was collected as part of a promotion.] These Sony Extra Bass Wireless In-ear Headphones are easy to set up and use. They are lightweight and can easily and quickly be put away or retrieved from a pocket or handbag. They are comfortable and stay secure in my ear, even when I am jogging. The battery lasts for quite a while. These have a clear sound and are good quality. The bass sounds great. I am very satisfied and would recommend this headset.

Rated 5 out of 5 by from Fantastic [This review was collected as part of a promotion.] This is by far the best headset i ever owned. Not to mention I already have a previous set for an older model of this brand and I absolutely love this one! The best part is the long lasting battery life it can easily live for a long day of work, running for errands, walking outside and working out in the gym and still got some life in it and it recharges pretty fast too just in couple hours. It is very sleek design fits perfectly in my purse or pocket. The sounds is awesome and the controls are pretty easy to reach. It gives me the peace of mind of not worrying to lose the earbuds. I would absolutely recommend it

Rated 5 out of 5 by from Great sound [This review was collected as part of a promotion.] So happy with my new headphones. They stay in my ears while I’m running or working out, even if I sweat. They are also super comfortable and never make my ears sore. They are easy to connect to your phone and the battery last for days. Great pair of headphones.

Rated 5 out of 5 by from That Extra bass is it! [This review was collected as part of a promotion.] I am so fond of these extra bass in ear wireless headphones. I actually prefer these type of headphones to the tiny ear buds I'm constantly losing. These fit comfortably in my ears, and have the little controls on the cord that I find are easier than trying to push the button while in your ear. The most important part to me is that bass! These headphones deliver on that. I'm always on the hunt for a pair that are loud enough and have bass, it's always one or the other, these have both! You most definitely need to buy yourself at least one pair of these godsends. You can leave your device in a different room and go further with these without your music cutting out, for instance I can leave my phone in the living room and go to the back of my home and these still play, excellent, clear and crisp brilliant sound.

Rated 5 out of 5 by from great sound quality [This review was collected as part of a promotion.] This is an awesome pair of headphones that I recently fell in love with. The sound quality that it gives out is super awesome. The fact that it is wireless helps me with meetings and on the go calls. I don't have to bother about detailing the wires. The battery life is very good lasting upto 15hrs. True of Sony's quality these are just wonderful. I would highly recommend it to anyone.

Rated 5 out of 5 by from Excellent headphones at a reasonable price [This review was collected as part of a promotion.] got these for my athlete son to use during workouts and he loves them. Fit comfortably, stay in his ears, and he likes the extra bass sound profile when he's lifting. Love the extra ear buds to custom fit for different uses, and to use while cleaning others after workout.

Rated 5 out of 5 by from Great sound [This review was collected as part of a promotion.] I am really liking the wireless in-ear Headphones from Sony. I have been using them when I take my dogs out on the trail running. They stay in the ear without falling out. The battery life is great and I do not have to charge them all the time. I really love the sound quality of these headphones. Will purchase another set for my husband.

Rated 4 out of 5 by from Easy to Use & Set Up [This review was collected as part of a promotion.] The Sony Wireless Headphones are easy to set up. It comes with the cord to charge and additional ear bud covers. The headphones are recognized immediately on any of the devices I have. I think the sound is alright but not great. It is not as crisp as I thought they would be. The earbuds can become a bit uncomfortable after wearing them for a while. In addition, I have to keep placing them back into my ear for them to stay. I like that the headphones are light weight. This is a basic budget wireless in ear headphone set.

Rated 4 out of 5 by from Great wireless earphone [This review was collected as part of a promotion.] I love wireless earbuds especially for working out. When not in use the magnetic earbuds attach to each other and stay put around your neck. Bluetooth connectivity and set up is very straightforward. Its charged by USB. Charging is relatively quick and last ample amount of time. The silicone earbuds fits snug. Sound is clear and bass is impressive.

Rated 5 out of 5 by from Great Headphones! [This review was collected as part of a promotion.] Sony did a great job! Set-up and connecting the headphone set to my phone was easy. It comes with multiple sizes of earbud covers to fit your ears better. The sound quality is good, and the mic picks up my voice well. People have told me they can hear me better when I use my headphone set. They are comfortable to wear, but they sometimes tangle. I generally wear them for basic day-to-day calls and not exercise. The charge on these headphones amazes me! My first charge lasted days, and I am on the phone for hours. It may take a few hours to charge, but when it lasts that long, it's no big deal. I have no regrets about getting these headphones. I use them all the time now.

Rated 5 out of 5 by from Awesome headphones [This review was collected as part of a promotion.] These are awesome wireless headphones. I love them. They are loud and have great bass. They are my absolute new faves. I highly recommend. Sound quality is A+. I wish they had a little better range, but I was able to listen to my music in the back room when my phone was in the kitchen, with just a little break up. I highly recommend.
