Review: السماعة غير جيدة، تصميمها غير مناسب، المغناطيس ضعيف من المفترض وجود مكان للسماعة داخل البدي حقها، عموما لم تعجبني وليتني احتفظت بالكرتون حقها لكي ارجعها
Review: ***Update: 8 months later and I am still using these on a daily basis. They still charge fast and the charge is still lasting just as long as when they were new. I made the mistake of falling asleep with them on, and at some point rolled over on them. As a result, one side doesn’t work:( I am about to spring for another so I can listen to music with full sound, and I will keep the one-sided headphones for work.*** I bought these two weeks ago. Will update if anything changes. I keep multiple Bluetooth headphones so I can use around the house, at work, and in bed. I really love my Santana Gypsy earbuds, but they last me 1-1.5 years and they are getting harder to find. I am not a headphone connoisseur or snob. I just like to listen to podcasts/videos, make phone calls when necessary, and rock out to my music once in a while. I couldn’t resist giving these a try considering the price, and so far I am very happy with my purchase. I like that these headphones seem to be very sturdy. They sit on my neck comfortably and the wires are not long to where I can catch them on things and break them. I can comfortably turn my head even though the wires are shorter. The earbuds fit comfortably. I added the included ear wings so they would fit more securely. Some reviews complained about sound, but I think these are fine, especially considering what I paid for them. When making phone calls, I realized I needed to be sure the end of the neckband was not sitting under my shirt collar. This ensures calls are clear and I can be heard as well. Now for the best part. The thing that absolutely blows me away about these headphones is the battery life. I was skeptical over claims these held a charge for 100+ hours. It is absolutely true! The day I received my order, I checked them on my phone. They connected very quickly and my phone showed they were already charged 100%. I took them to work that night and after a full shift they were still at 100%. Nice. I used them every day, off and on throughout my day at home as I made phone calls and did housework. I used them at work during my entire shift. I used them when I came home and went to bed, winding down for a while before falling asleep with them on. The next morning, they were at 90% battery charge. What?! I continued this for 10 days without charging them a single time. When I got to 20% on Day 10, I got a prompt telling me to charge them. Even then, it was still 3 hours before they shut off (previous headphones had given me about a 10-minutes warning and that was all). When I finally charged them it took just under 3 hours and I was back to 100%. I love this! I hope these last a long time. I look forward to being able to vacation at a remote cabin and not worry about them running out of power if my hubby snores at night :) I would highly recommend you give these a try!

## Questions & Answers

**Q: Does this come with a wire for charging or can you use your Iphone cord for charging?**
A: Yes charging cable with Type-c interface

**Q: Is this wireless headset amazing?**
A: Yes, it has a long playing time and is a good choice for you to travel and listen to songs

**Q: Can this be used in the pool?**
A: I'm afraid this won't work, it only protects against rain and sweat

**Q: Does this connect to two devices at once?**
A: Yes, but you may have a problem getting it to go into pairing mode if it is automatically connecting to a prior device. So turn off the Bluetooth on the prior device while you pair it with the second device. Then you can have both devices connected, but it will pause one of them while the other one plays. I learned this from the manual for another BT headphone.

*by B***Y on 1 October 2023*

Update #3 10-1-25 So, I'm getting 6 to 8 months use. My 3rd replacement pair just died. They didn't appear to have any problems until I wore them in the shower. After that, they will pair with my phone for about 20 seconds, then disconnect. Not worth it to have to replace them so frequently. There are now many long play earbuds on the market so I am trying a different brand. Update: 3/9/25 Well, my 2nd pair have died. About a week ago they started using an insane amount of battery power, then last night they refused to charge although the charger is verified to still work. These are still the best earphones I have ever used and I will be getting a new pair as soon as I can get them shipped. Update: 8/2/24 I ordered a pair of the green earbuds to replace my original purchase from 2023 that lost audio on the left earbud. Same great sound. Same great battery power. Same waterproof-ness. (I showered and washed my hair and it came through with flying colors!) The only thing that is appreciably different is that the green ones have a blinking red light that can be a little disconcerting when I awaken in the middle of the night. It's not a bright light. I can't see it in the daylight. And this is not a light to show that it's charging. I'm not sure what it is for, except to annoy me and reduce the battery charge. And while I am THRILLED that the battery lasts me all week, it VERY annoyingly starts telling me to charge it when I still have 20% capacity left. I can get about 3 whole days of use from 10%. It would be nice if the reminder came at 10% instead of 20%. But these are very minor caveats. These are still my very favorite earbuds and I very definitely would (and have) bought them again. I paid full price for all sets of earbuds and received nothing in payment for my honest review(s). Update: July 7, 2024 I do still like these. The battery life is still awesome. I almost never have to charge these. The only change is that, as I feared, the left bud has stopped working. But I like these enough that I ordered another pair. However, I thought that I would upgrade to the I39s. That wasn't such a great purchase. The battery life sucked, and they were not waterproof. I will try to review those earbuds through that purchase, but will include here just in case that isn't possible. I do still recommend this "lower" version. I bought these in June, 2023. I use my headphones every day. I listen to music and podcasts and for phone calls. I can't claim to use them at work much because earphones interfere with customer service, but I certainly plug them in as soon as I lock the door and start the nightly cleanup. My partner has been out of town for the last week so I've also been using them for hours at home. I haven't charged them since the day he left. When I checked this morning, I still had 30% left. I have a super expensive set of aeropex air shokz that I'm lucky to get 6 hours out of. Those stupid things start telling me to "charge me" when they are at 40%, and I had better pay attention because at that point I only have about 30 - 40 minutes left. And these are much louder than the aeropex also. I no longer strain to hear my podcasts when driving or in moderately loud situations. What I don't care for is that the neckband makes me sweat. I live in Anchorage. There's not much that makes me sweat. Also the wires for the buds are flimsy and I know that they will break. The biggest problem I've had is that I tried to pair them with my partner's phone before he left on his trip so that he didn't have to worry about charging, but I could never get it back to pair mode. As long as I keep my phones, that probably won't be a problem for me, but it's disheartening to know that I can only use them with my phone.
