AMAZING Battery Life!
Okay, wow. Where to start? The value for these earbuds is beyond amazing. I have basically zero complaints, but I’ll try to give a well-rounded review.The Feel:As someone with small ears, I do struggle to keep these in at times. No matter what size tip I use. For some reason my right in particular refuses to stay in but I finally figured out how to get the left to stay. This is more a me issue though, nothing to do with the buds. They don’t hurt at all, and despite looking a bit bulky in your ear, they’re really not at all heavy.The Sound:If you’re looking for a sound system to blow you away? These probably won’t do it. If you’re not super picky and just want a clean, crisp sound for music? These are great! I don’t think they’re revolutionary in the sense of their sound- so those seeking the BEST sounding earbuds will look elsewhere. However, for the average listener, I really can’t complain. They’re clear, crisp, and plenty loud if you want them to be- without blasting those around you with your choice in music. :PThe Battery Life:O. M. G. I can’t even begin to praise this aspect enough. I bought these mainly for my bf to use on his way to and from work (he walks) but we both use them throughout the week. It’s been two weeks. Each earbud gets about 10 hours, give or take, of use PER DAY between the two of us. WE HAVEN’T CHARGED THEM YET. When I tell you the battery life on these things is possibly far better than advertised? I mean it. Like… I’ve been on calls with these things for 6+ hours NON-STOP and I don’t even get a low battery warning. I don’t know what it is but I think the battery in these will be hard to beat.The Mic:VERY impressive. Each bud has a mic in it and it is very clean and clear. It blocks out background noise VERY well. Not much to say here other than 10/10!! I like that each bud has a mic because I often only use one at a time when taking calls and these can do just that!Overall:Extremely impressive ear-buds for the cost. They’ve got a nice, sleek design and the charging box is convenient and long-lasting. It is a bit difficult to press the answer/end call button on the bud itself while it’s in your ear, but that’s not a huge deal for someone like me. I just grip the bud in my ear by the edges and push to keep it from pushing further into my ear.If you’re looking for a general use type of wireless mic / earbuds, these are a great, solid choice. I’m so impressed with these it’s crazy.

Great little earbuds for third of the price of AirPods, although a few problems with battery life
EDIT (23/08/19): Added in battery life testing, will slightly change my opinions about these earbuds but they’re still very great otherwiseIâve bought from Back Bay Audio prior to buying these earbuds (American EQ 40) and because of that, I knew these earbuds would be amazing from the start.Where to start? Well, of course, great audio quality as I was expecting from Back Bay Audio, banging bass! I use a customised EQ on Spotify all the time and these earbuds really bring out the lows and highs (which is my preference, I usually keep the mids pretty quiet). To be honest, I actually found these earbuds to have better sound quality than the American EQ 40s, these earbuds sound more fuller than the EQ 40s.Battery life; during my testing, the claims for 8-hour playtime is true. 40-hour total playtime, not so much. Iâm not sure if itâs because of the battery capacity itself or because of standby time. Youâll find my battery life testing at the bottom of this review. Thereâs one thing Iâve noticed as well, on every occasion where the right earbud runs out of battery, thereâs always 60% battery left on the left earbud. And also right when the charging case hits 25% battery (indicated with 1 quick flash of the blue light), it stops charging the earbuds altogether even though when it just flashed 2 times earlier.Comfort; using it for the first time was a bit difficult to find the perfect spot for the best sound quality (even right now while Iâm listening with these earbuds while writing this review, I still have to adjust a bit to find the just-right spot). Unfortunately, because of this, I have to give it 4 stars in comfort, but when I do find that perfect spot it sits there perfectly without falling out.All in all, if you want great sound quality with excellent battery life in your truly wireless earbuds and donât want to spend over $100 on AirPods, the Back Bay Duet 50 Earbuds are a major go!BATTERY LIFE TESTING:All battery readings are from the battery widget used on an iPhone XR with iOS 13 Beta 5 installed, so there may be inaccuracies with the readings.Charging case at 75%Test #1 (7 August): ~9:00 AM – 4:49 PM7 hours 49 minutes total100%, drained to less than 10% leftListening to SpotifyTest #2 (7 August): 4:58 PM – 6:11 PM1 hour 13 minutes total20%, drained to 0%Listening to SpotifyTest #3 (7 – 8 August): 7:50 PM – 12:34 AM4 hours 44 minutes total100%, drained to 50%Mostly watching YouTube, listened to some SpotifyCharging case fully chargedTest #4 (8 August): 10:59 AM – 11:50 AM51 minutes total100%, stayed at 100%Listened to SpotifyTest #5 (8 August): 12:58 PM – 6:36 PM5 hours 38 minutes total100%, drained to 50%Mostly listened to Spotify, watched a bit of YouTube and took a few callsTest #6 (9 – 10 August): 11:02 PM – 3:20 AM4 hours 18 minutes total100%, drained to 60%Watched YouTube for most of the timeCharging case at 75%Test #7 (10 – 11 August): 4:24 PM – 12:17 AM7 hours 53 minutes total100%, drained to 0%Mostly watched YouTube, a bit of SpotifyTest #8 (11 August): 11:35 AM – 11:45 AM10 minutes total100%, stayed at 100%Listened to SpotifyCharging case at 50%Test #9 (11 August): 12:48 PM – 8:35 PM7 hours 47 minutes total100%, drained to 0%Listened to Spotify mostly, watched a bit of YouTubeCharging case at 25%, but doesnât seem to charge the earbuds or turn them off anymoreTest #10 (11 August): 9:39 PM – 11:31 PM1 hour 52 minutes total100%, drained to 90%About half/half with Spotify and YouTubeTest #11 (12 August): 12:53 AM – 4:02 AM3 hours 9 minutes total90%, drained to 50%Mostly watched YouTube, bit of SpotifyTest #12 (12 August): 3:21 PM – 5:09 PM1 hour 40 minutes total50%, drained to 0%Listened to Spotify the whole timeTotal playtime: 33 hours and 18 minutesCharging case fully chargedTest #13 (13 August): 3:02 PM – 8:55 PM5 hours 53 minutes total100%, drained to 50%Mostly listened to Spotify, a bit of watching YouTubeTest #14 (14 – 15 August): 5:37 PM – 1:02 AM7 hours 25 minutes total100%, drained to 40%Mostly watched YouTube, listened to Spotify for a bit.

Good quality earbuds, sound quality is pretty good as expected of Back Bay. The material of the earbuds is pretty sleek. The only complaint is that the casing cover seems abit flimsy but for the price, it is worth the money.
