KinivoBTH240 PRO Bluetooth Wireless Headphones (On-Ear, HiFi Stereo Music, 30 Hours Playtime, Built-in Mic, Foldable Headset, Hands-Free Calling)

I bought these headphones for my laptop because I was afraid I'd break the cord on my nice ones. My older bose earphones (IE2) fit so well, I would forget I was wearing them and walk off, pulling the headphones out of my ears or the cord out of the computer. I didn't want to break these, so I decided to look for some wireless ones.I read the reviews on these, and I am glad I purchased the Kinivo brand headphones over some of the others. There are other sellers, but what they are selling are the same as the inferior Kinivo BTH220 headphones. Some of them even have 240 in the name, but they're the same design as the Kinivo BTH 220. The Kinivo BTH240 headphones have better buttons on the right earpiece. They have less travel, and they feel higher quality.Pros:1.)Light- I can wear them all day.2.)Great battery life! I get at least 10 hours of constant music playback. If there isn't constant audio, they last much longer. Basically, you get 10 hours of constant audio playback. If you aren't playing audio but they're still on, they last longer.3.)Excellent sound quality! I have been using Bose IE2 headphones, which I consider relatively good quality. There is NO noticeable decrease in sound quality with these headphones over the Bose ones. The bass is excellent, and they don't sound remotely cheap. I thought for the price, there might be some static hiss like there was with a pair of Sony Bluetooth headphones. There is no background noise whatsoever! I would have to take my Sony headphones off when I wasn't listening to something because the hissing would gradually drive me crazy. These surprisingly are completely silent. The Sony Bluetooth headphones also costed more than twice as much.4.)Design and functionality: These "on-ear" headphones are relatively comfortable. When you are sitting or lying down, they aren't very noticeable. If you try to lean your head on something, they can be uncomfortable. I elaborate on this more in the cons. The headphones themselves look fine. They are plastic, but they're not cheap looking or feeling. All of the buttons (next, previous, volume up/down, and the middle button) work great with my computer and phone. The center "other" button held to turn them on and off, and pressed once to pause/resume audio/video and take calls. All of these buttons are on the right headphone. They are big, and I learned their placement very quickly. They also don't require much force, so you don't have to press very hard and put pressure on your ears. Another design feature that I LOVE is that they charge via MicroUSB! This means I don't have to carry a special cable. The cable for my android phone and tablet also works with my headphones! Sony could learn something in this department! They include a USB cable to charge them from a USB port on a computer. I just use the one for my phone. They are full in a few hours too, so it doesn't hog the charger.5.)Fantastic value! I paid $25 for these headphones with a $5.00 amazon discount coupon. For $25, I wasn't expecting anything close to my Bose in ear headphones. I honestly cannot tell the difference. Obviously the form factor is different, but the level of audio detail is amazing. When comparing my Bose earphones to the old apple ones, I would notice little things in the music I had never heard before. These headphones have as much audio detail as my Bose ones do. If you are familiar with the old apple headphones and thought they were alright, these Bluetooth headphones will be a serious upgrade. For high quality headphone users, these certainly aren't a noticeable downgrade. If I had to guess a price for these just based on sound quality, I would put them in the $75-$100 range. These are seriously on par or better than the Sony Bluetooth headphones that are in that price range. The fact that they cost $25-30 amazes me.Cons:1.) It isn't easy to lay down with these on. If you try to lay on your back, the band that goes around the back of your head gets moved, pushing the headphones forward about a quarter inch. In this position, they are uncomfortable. A pillow minimizes this effect. You also can't lay on your side unless you want the headphones pushing against your ears. Again, a pillow minimizes this.2.)Constantly blinking LED. While in use, they have a bright blue LED that flashes every 7 seconds or so. It is bright enough that I can see the light blink on my shoulder if I'm in the dark. This is a minor annoyance, and can easily be solved with a well placed piece of duct tape, or a permanent marker if you just want to make it less bright.3.) They are relatively loud to people not wearing them. If you are in a quiet room and listening to music, the people around you can also faintly hear the music. It isn't very loud. For comparison, my old apple earbuds are louder when they're taken out of my ears. This is just a minor annoyance because I might want my voice calls to be private. If you're in a car however, a person in the seat next to you can't hear the conversation over the noise of the vehicle.All things considered, these headphones are an unbelievable deal! I wasn't expecting this level quality, both sound and design, in a pair of headphones for under $30. Beware of other companies that are selling a similar product (cough cough SoundBot cough). They say they're the 240 model number, but they actually correspond to the Kinvio BHT220 headphones. The BHT220 headphones had some problems that are fixed in this model (BHT240). They are all made by the same factory, but I haven't seen any of the other nameless brands selling this model of headphone.If you want to chance it with the other nameless brands, fine. As far as I can tell though, they're all selling what is equivalent to the Kinivo BHT240 Bluetooth headphones. If you find another brand with this model of headphones for less than $25, I'd like to know. At the time of writing this review, I can't find this model of headphones from any other brand. Maybe Kinivo is just the first to release them.I will be recommending these to all my friends. I like that I can listen to audiobooks and music almost anywhere in the house. It is a serious convenience that you can't fully appreciate until you've experienced it.UPDATE 2/12/2014:I have been using these wireless headphones for a while, and I absolutely love them. I want to mention another feature I hadn't really acknowledged. They reconnect to my computer super easily! I just turn them on, and they connect within 20 seconds. My computer speakers are muted and the sound is directed through the wireless headphones. I forgot to mention this because it is so seamless. The more I use these headphones, the more I love them.

I got these for $25 from Amazon. I think that's a spectacular price. I go through headphones quickly, and got tired of paying $50+ for headphones that only last a couple months. The buttons do feel a little cheap when you press them, but I find that perfectly acceptable at this price point. More importantly however, I think that the actual design of these will give them above average durability, even if they don't have a superficially durable feel. The one worrying aspect is that the joints that allow these to collapse is plastic held together with a tiny metal screw/pin. After only a small amount of time, one of the screws on my unit was sticking out a little and scratching my neck. I happened to have a precision screwdriver on hand to address the issue, but I wouldn't be surprised if the screws had a tendency to continue to come loose with normal use. As a precautionary measure, I've put electrical tape over the joints to prevent further problems. I think the overall design would be more durable if they were to just dispense with the hinges and make the headphones not collapseable. Since you can comfortably wear them around your neck when you travel, I don't think that the collapsing feature is important enough to make up for the decline in durability and user experience (the neck scratching).I do find these more comfortable for all day wear than every other pair of headphones that I've owned. The ear padding is very soft, and the headphones stay secure to your head without pressing in on your ears (which I find uncomfortable over long periods). It also helps that it's also easy to hang them around your neck instead of on your ears when you're not using them. This is significantly more awkward with many other headphone designs.They are even fairly comfortable to wear while laying down. The softness of the cushion deserves the credit. It's not even uncomfortable to lay directly on your ear with the headphone resting on a pillow. I don't think I can say this for any other pair of headphones that I've had, including earbuds. I also think that the comfort level of these headphones isn't as dependent on the shape of your ear as it is with most headphones. They just seem to be designed to be as comfortable as possible for all ear shapes.Aesthetically, these look a little goofier than I was expecting. The issue is that each earphone has a small radius, but is very thick. They kind of look like little sliders (the small hamburgers) glued onto your ear. If aesthetics is very important to you, then you might have to spring for a more fashion oriented model.As for ambient sounds, when you are wearing them, they are a bit muffled, but not blocked. It's a little harder to understand people that are talking to you, but you'll hear that they are talking if you're not blasting music. On the other hand, they are loud enough that you can follow spoken word when ambient noise levels are high (this is a problem with a surprisingly large number of headphones, but not these). When the music is off, it's possible to carry a short talk without taking them off, though it would be a little annoying, manners aside, for a longer conversation.I don't care much about audio quality beyond a certain level of competence, but have gone through dozens of headphone models, and these are decent on that count, certainly better than your typical earbuds. I've never really gotten why so many professional reviewers put so much emphasis on this aspect for portable headphones meant to be worn out and about in conditions that are far from ideal for attentive listening. So I put this section at the bottom of this review. I expect that these are perfectly adequate for almost everyone, but if you happen to be an audiophile, well I don't think these are the aural gold mine you might have been hoping for.
