My original review of this product wasn’t great to say the least but I do want to add this info as I just completed my warranty claim with Bose on these earbuds and I’m very happy with the outcome. My original review is still available below and although I do still have the same feelings for this exact product, the problem was rectified by the manufacturer. I contacted Bose with the issue I was having and was emailed a shipping label to return the earbuds and was offered their newest model (Quiet Comfort Ultra) as a replacement. Within 7 business days of me sending my earbuds in to Bose I have received the new product which came brand new in the original packaging and for this I’m beyond grateful. I decided to leave my original two star rating however because it pertains to the original earbuds that were a nightmare. If I were to review the new model they had sent as a replacement it would be 5 stars though!Original Review (before warranty replacement)Let me start by saying that I am a huge Bose fan and would consider myself very loyal to the brand. The very first product I purchased was the 3-2-1 home entertainment system probably around 17 years or so ago and since then if it has anything to do with speakers for me, it is most definitely a Bose product. This even includes my vehicle which I am thrilled that Cadillac always have Bose speakers installed. As for earbud headphones, I started with the Bose SoundSport model and they were great. Unfortunately, after almost a year and a half of heavy use the batteries were shot and only lasted about 30 minutes on a full charge so I upgraded to the Quiet Comfort model which I also loved. Unfortunately, after owning those for a year the glue that held them together began to break down and one of them separated into two pieces and would no longer play sound. For the amount I use these, I don't think that them only lasting a year was that bad. I basically wear them for at the least an hour every single day and most days 4+ hours. It was after the Quiet Comforts fell apart that I purchased these Quiet Comfort II series earbuds and the first thing I noticed was that there didn't seem to be much of an upgrade in sound quality or at least it wasn't as noticeable as the upgrade from the SoundSports to the first Quiet Comfort model. After a few days of using them they began to constantly lose connection to my iPhone & iPad and most of the time when this happens, a simple reset won't fix the issue and they refuse to connect to any of my devices. Ive tried everything to correct this when it happens, forget them in my phone's settings, erase them from my Bose Music app, etc. Nothing corrects it other than time. After a few hours of being in their case they will connect again after being removed but this is happening more frequent than not and it is extremely annoying. They also very recently started doing this thing where the sound gets all distorted while using them and then it will start playing sound from only one side for a few seconds and then it will switch to the other side and back continuously for a minute or so. It just really shocks me that I had absolutely zero complaints on any of my previous Bose earbud models and here I am having a nightmare of a time with these Quiet Comfort IIs. I did notice there is a new series/model out now(Quiet Comfort Ultra) and I really wish my Quiet Comfort 1s lasted just another two months or so as I would've just purchased whatever the newest model was at that time but to now spend another $300.00 +/- after just spending $275.00 on these only four months ago is very upsetting as well as the thought that the new model might also not be the same tremendous quality that I believed my previous Bose ear buds were. To tie up this review, I can't say enough good things about Bose products, however I would personally stay away from this model as they've been nothing but issues for me since the very first few times that I used them.
