    Great little earbuds for third of the price of AirPods, although a few problems with battery life
    5 Stars
    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 otherwiseI’ve 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. I’m not sure if it’s because of the battery capacity itself or because of standby time. You’ll find my battery life testing at the bottom of this review. There’s one thing I’ve noticed as well, on every occasion where the right earbud runs out of battery, there’s 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 I’m 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 don’t 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 doesn’t 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.

    5.0 out of 5 stars I'm impressed--Amazing Quality and Value!
    Reviewed in the United States on January 21, 2024
    Like a lot of people, I've been trying to find a high quality pair of earbuds that fit right and work well--that also don't break the bank. Been there, done that... I bought a $200 pair of Bluetooth earbuds from a BIG, well-known brand. They were great! But in just over a year of use, the right earbud completely lost the ability to hold a charge. :( So disappointing. Prompted by positive reviews, I bought these Back Bay Duet 50 Pro buds. I can't speak to their longevity yet, but right out the box I am really impressed. The sound quality is easily comparable to the $200 buds from before. The controls are on point, and I happen to much prefer the push-button type of control versus tap. I have a slight tremor and I believe it affects my coordination with the tap, haha. I realize it's a unique-to-me issue, but nevertheless, the push button feature works seamlessly in any case! As for fit, I switched to a medium tip, which maximized the bass and comfort. I have a bit smaller sized ear canals, but these sit so nicely without creating any ache, which is a major plus. Because Back Bay provides 6 different sizes, you're sure to find the perfect fit for your ears. I'm pleased at the various features, such as a dust and sweat resistance, LONG playback time and robust powerbank capability of the case. It can even charge your cellphone with the included cord/adapter. I'm looking forward to testing out the phone call quality due to the CVC noise cancellation. I am really happy with the purchase!

    Pros
    - good enough battery life at price point
    - good sound quality
    - good distance / strong connection
    - good price
    - earbuds have fit options

    Cons
    - Advertised that each charge of earbuds should last 8 hours, but only lasts 6 hours, I tried this 3 times.
    - Not great for charging a smartphone, as the full charge was only enough for 8% of total batteries. For emergency use only.
    - see image: my earbud fits came with one tip missing. Contacted their support, and they said they'd mail me new ones, and send shipping info. Been a week, and haven't heard from them yet

    Overall: for the price, I'm pleased with the product as long as the battery life doesn't decrease significantly with use.
