Mi esposo me compró estos audifonos y Empecé a usarlos el dia que me llegaron un Enero 28 de 2021, los use diario minimo 2 horas y nunca los cargue hasta Abril 11!!!! Mas de 2 meses y la batería no se descargó!!!!! Esto es INCREÍBLE!!!Otra cosa que me gusta MUCHO es que puedo retirarme super lejos y no pierdo la señal!!Y por último me encantan xq se oyen PERFECTO!! Me gustaron TANTO que ordene unos para regalárselos a mi hermana!!Battery life is good but echo is coming from speakers.they are embarassingly large and ugly. I am embarassed i bought them for my 17 year old son. more pink than red. I dont know how they sound, but do you yourself a favor and only buy the black ones, and only then if you dont mind wearing something the size of two rolls of nickles around your neck.Very goodIt’s good with phones but with pc, creates a lot of echo and the person on the other side can’t hear you clearly. If you are going to use it with a phone, a definite yesI have used a lot of headphones in this specific style - neckband with attached earbuds. While I do listen to music with them, my primary use is for work. I need to hear my cell phone as I use it along with a bar code scanner. So with that in mind, here are my pros and cons:ProsSound was pretty good for this price point. Was actually impressed. YMMV of course.Comfortable for the most partLong battery lifeAccepts TF memory card. I won't use this, but I know others willAffordable pricePaired with my Android phone in secondsConsBiggest issue - these won't last very long. Every single neckband earphones I've ever used has failed when the cords to the earbuds become damaged. Other models I've used have had earbuds that magnetically attached to the neckband when not in use. This model does not have this feature. When the earbuds are not in your ears they dangle. And THAT in my many years of using this type of product will result eventually in a pulled cord and then ultimately damage and failure. How long these last will depend on how you use them of course. I typically can go a few years before having to replace my earphones. I believe these will not last as long as my last set, but I think it will last me more than a year.NeutralEarpieces are a little unusual in my experience. Not circular, more intended to fit the shape of your ear. It's okay. I prefer what I know, but this will probably be fine for me. Again, YMMV.These neckband style headphones are unique.They have the classic earbud design, so they sit well in your ears, but don't go in to the canal.They still manage a good full range audio sound considering the earbud style, and this is partially due to the large driver they use to convey sound.they also have a cool feature, insert a Micro SD Card in to the slot, double press the power button with the headphones already powered on, and they become an MP3 player.A great option if you want portable audio without carrying a phone around.call quality on these is also pretty good.Voices come through clearly, and your voice will sound a bit distant to callers, but is easily audible. background noise is canceled out well.Over all, these are a great option if you want a neckband style of earbuds at a great price.Battery life is surprisingly long. I found it more comfortable without the silicone pieces. Sound quality is better than expected! Would recommend and purchase again!
