*******INSTRUCTIONS AFTER LONG-WINDED REVIEW, PLEASE STAND BY*******Ultra mega, super deluxe, highly recommended, long lasting, great value headphones...I've tried many different Bluetooth earbuds throughout the past 2 years from Amazon... these are by far the best yet for my needs, was looking for a pair to get through a full work day without recharging.. i personally prefer the neckband style as opposed to the fully wireless separate buds while at work, for fear of losing them easier, and the batteries dont last as long...The promise of 100 hours of play time, and while I haven't gauged the accuracy of that claim, a full charge will last at least 5 days , while running 24 hours daily.. (yes, I use them while sleeping too) I've been using them for over 2 months or so, and they've held up great so far... many others I've tried from here didn't last this long, a few had issues in the first week, either one speaker stopped working, or they stopped powering on, or the battery life dwindled down very fast, some claimed 50 hour battery, eventually drained within 4 hours, and many other issues...No problems at all so far with these, outlived them all and still running strong..While my main concern was just to have long battery life, above sound quality or anything else, these are packed with extra bonus features to put these far ahead of the rest for the price point.. beyond the long battery life, they actual do sound rather good, crisp clean clear highs and deep punchy lows, decently loud volume without distortion.. fast Bluetooth connection, no lags or glitching, good range of distance from device, very comfortable in ears, extended controls, including a digital assistant button to control your phone through voice commands, the option to insert a micro SD card (not included and must be 64gb) so you can use without a device connected and save power on your phone. I have yet to use either of those last 2 options, but it's nice to have them. The other feature I find useful is the LED battery meter located near the control buttons, it's nice to visually check battery life, as opposed to waiting on the unsuspecting annoyingly loud voice announcing "battery low" interrupting every 10 seconds, while lowering the volume of whatever you're listening to as soon as the battery is down to 30%, as all the other sets I've tried would do.. while these will still use the same announcement, at least it waits until you're below 10% and is not as frequent, though you'll rarely experience that, considering how long this battery lasts.I'm sure I've overlooked a few features here, but overall a very good value above all the others I've tried, I highly recommend, and would absolutely buy again if I had to.Only 2 very minor cons I could find, which honestly don't bother me at all, but I figure I'll put it out there for whoever it may concern...The first being the bulky size of the batteries (yes there are 2) that's what those big bulbous things on each end of the neckband are, while they may appear too much for some people, they're not that bad, they function as counter weights to keep it balanced on you're neck, and they're really not that heavy, I don't even notice I'm wearing them, they're rather comfortable all around..The other slightly minor con, which I've seen other reviews complain of is the language setting.. they seem to be in Chinese by default, and they provide no instructions how to change it...****SO HERE IT IS********HOW TO CHANGE LANGUAGE ****Turn on the headphones- a voice will say "Power on" but most likely will be in Chinese...*****IMPORTANT NOTE******KEEP THE PHONE'S BLUETOOTH SETTING OFF WHILE POWERING ON HEADPHONES, THIS SETTING WILL NOT WORK WHILE PAIRED AND CONNECTED TO PHONE!!!!!!!!With headphones power on and NOT connected to phone yet (Bluetooth off) -There are 5 control buttons on headphones - locate the button labeled C (3rd button from bottom, right above the Volume +/up button) press the C button 3 times in a row in a steady fairly rapid fashion, you should then hear a voice say "English" - if not, try the triple press again, you were either too fast or slow between presses.....And there you have it! once you hear the "English" announcement, you can then proceed to turn your phone's Bluetooth setting on and pair as directed in the instructions... from there you can go about your life and enjoy not worrying about battery levels for about a week or longer depending on use.Thanks for reading, hope you enjoy these.

I had a LG head set before and I miss the retractable head phones and motor for vibration, but over all I like this one better. The built in MP3 player requires a SD card, sold separately, but is easy to access and handy.

Los compré por los comentarios, vienen igual que las imágenes, trae su bolsita y si pude cambiarle el lenguaje con la ayuda del primer comentario, me gustaría que estuviera en español, sin embargo en ingles esta bien, los auriculares son cómodos, solo no pensé que le darían tanta tentación a mis gatos, tendré que cuidarlos mucho.

Buen producto por el precio, solo que siempre que inicia una canción el volumen lo da al máximo...es molesto
