1Mii Airplane Bluetooth 5.3 Adapter for Headphones W/Portable Charging Case Support aptX Adaptive/HD/Low Latency for Use on Airline

UPDATED REVIEW: After I posted the review, the company reached out to me & addressed my concerns, sent me an updated adapter that was improved & I just returned from an international flight where it worked as advertised. You might have to wiggle it in the headphone jack to get it connect sound to both ears, but that's not a manufacturer error. Watched two shows & a movie with no issue in dropoff, lag or battery so I'm giving them back the stars I took off for the quality & the customer service. I appreciate them reaching out to address my issue & making it right. Highly satisfied with the purchase now. Good work, 1Mii!ORIGINAL REVIEW: I travel a fair bit for business & leisure so really wanted this adapter to work. Had high hopes when I read the reviews but after I charged for its maiden voyage to Europe, it failed to work at all. I ended up plugging the USB-C charge cable into the adapter itself & then sound worked out of one headphone. Half the time I try, it either doesn't hold a charge from the case as it should or doesn't work as advertised. Out of the 8-10 times I've tried it since I bought it, I've only successfully gotten it to do what I bought it to do once. It's not cheap either, so that compounds my disappointment with it. I'll continue looking for a solution that does what it should as I would advise you to as well.

I got this to use with my wireless headphones on flights. It worked really well for two flights, and then my most recent flight it completely stopped working in the middle of use half way through my flight. The sound progressively got scratchy, then soft to the point where people talking in the movie sounded like they were whispering and then finally just stopped working. I would return them, but Amazon states its past the return window. This is a subpar product buyer beware.

I tested this with Bose QC35 headphones attached to the monitor on my PC (HP 34" HiRes monitor).With the PC volume at 100%, the headphones cranked all the way up and the VLC media player all the way in the green...I was only hearing sound out of the right earpiece. That sound was very low in volume. So, I started writing this review...and...then I thought...let me plug the other plug into my monitor. Presto! Both earpieces working and a decent volume. Maybe this "tip" should be in the manual?I hope that this helps somebody else.Having used this some now, I have to say that the range advertised would appear to be ONLY outside with nothing blocking the communications. I can't get 10' away from my home office PC with this device before I lose music playing (actually I can get about 20' in a direct view of the iMii B05 BUT as soon as I have a wall between me and the B05....it disconnects). I took off 1 star for this. As I intend to use this on my office PC to lose the cable or on planes I am going to keep it. Anyone wanting longer range than I see should probably look at something else for this.After using this for several weeks, I still like it.One suggestion I would make to the manufacturer is to enlarge the case to accommodate keeping the cable in the box also.I have lowered this review to 2 stars as I get virtually no volume from this device now (now 4 months old). Using a cable from my monitor to my headphones in in place of this device works fine. I have emailed the company for support. I'll post again IF or WHEN I hear from them.I have raised the review by 2 stars. I heard back from the vendor customer support the same day as emailing them. They are sending me a new one. Good customer support from this company! I really like how this device works.Update 11/6/2021The new B05 arrived within 2 days (excellent customer service!)...so see my "story" below:I received the new device today…many thanks. I cleared out the Bose headphone BT connection and paired the headphones to the B05. Low volume still. Tried the Bose cable again…volume OK.Really odd, I thought. I had already gone through all the Win10 properties before I contacted the vendor. So, I went through them again. Couldn’t see any issues.I nosed around the web but couldn’t see anything about Win10 low volume using BT that was useful to me. I looked at the headphones and raised the volume. Now, using the B05, I can get volume again on the headphones. What is really odd is that I did NOT turn the volume down on the headphones.Maybe my story above will help some other customers in the future?

This thing is great!! It feels a little cheap, not like my airpods and case but it works great! I sync it up with my AirPod pros. Love the fact that i don’t have to resync it every time i use it. It remembers my airpods. I use it mostly with my Nintendo switch. Haven’t used it on a plane yet (freaking covid) but if it works flawlessly with my switch I’m sure it’ll work on the plane. Highly recommendedUpdate. After 5 months of use the charging case will not charge the unit. The case still does charge but doesn't help much if i can't charge the bluetooth itself. The bluetooth unit has a charging port so i have to charge it there but now it only lasts one charge and the case is pretty useless.Update. So i changed my review to 4 stars. I contacted customer service and they replied in a few hours. They sent me a new replacement in 2 days. Great customer service. Good product, one star off for durability

I bought this before my series of long haul flights across Asia and Europe as I wanted to use my own aNC headphones instead of the ones provided by the airlines. These adapters paired perfectly with both my Sony ear buds and B&O H95x. The connection was strong and audio clarity was great. They lasted through a 7 hour flight and were ready to go the next day (after being charged in the case). The case does take a lot longer to reach full charge but you can also charge the case and the adapter in the flight.

It was said to last 6 hours + 24 hours (case). It worked through my 13hour flight without any charging but on the return flight , it lasted only 11 hours. Still it did more than the 6 hour touted. Connection was stable that I could go to the lavatory with my headphone on. Sound quality equally good. Definitely worth every penny.

I was impressed with the packaging and build quality of this product.Unfortunately, there is a latency in the sound transmitted to headphones - which means the audio and video are out of sync! Making the product unusable.I have an email from 1Mii confirming that the product doesn't work with Apple airpods!Sadly I missed the return window because I was traveling - so now I'm stuck with a Bluetooth adapter that doesn't actually work properly.

I owned a few of these Bluetooth airplane connection devices. This is one of the best and the fastest to connect to the earphones
