Review: I'm impressed--Amazing Quality and Value! - 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!
Review: Great sound - These are great ear buds. They feel great and the battery life is awesome. I love to take them camping with me, gives me an extra charger, definitely recommend

## Questions & Answers

**Q: Do these earbuds have active noise cancellation?**
A: No, but the earbuds do have very good passive noise isolation. When you are playing music through the earbuds, you cannot hear your surroundings if you use our isolation ear-tips included with your earbuds.

**Q: How many mics do each of the buds have?**
A: Each earbud has one mic. (So 2 mics total)

**Q: I can't get the larger buds on the earbud. If i can't get a solution i will be returning them**
A: My 9 year old got them on with no problem

**Q: I've got l & r connected on my devices but i'm only hearing sound from one of the earbuds. how can i get the sound to play on both sides?**
A: To listen to both earbuds at once, only connect to "D50R".  If that doesn't work, just do a quick reset and it will fix the issue. Reset instructions are here: https://www.backbayaudio.com/pages/duet-50-reset-to-default-settings

### ⭐⭐⭐⭐⭐ Great For the Price
*by A***N on July 14, 2020*

I’ll start by saying these are not the best sounding earbuds I’ve used. They are, however, the best sounding TWS earbuds under $80 that I’ve used. The five star rating is in relation to the $55 price point. If I had paid over $100 for these, my rating would be lower. For $55, though, these are seriously impressive. I purchased them to hold me over while I’m waiting on my warranty replacement from Jabra on the Elite Active 75t that only lasted me about three months (never buy Jabra). I’ve been waiting almost two months for that replacement and needed something in the meantime. I didn’t want to spend a lot of money, so I ordered some cheap Anker earbuds. They were okay, but then I saw a review for these on the Gamesky YouTube channel and they seemed impressive. They are SO MUCH BETTER than the Ankers were, and for only $15 more. For one thing, they’re tiny. They’re at least as small as the Jabras, maybe even smaller. They fit in my ears better than any earbuds I’ve ever owned. The fact that they come with six different sized tips to try certainly helps. The passive noise isolation is impressive. The only downside is that there is no hear-through mode (for $55, that does seem like a lot to ask for), and I can’t hear anything outside of the earbuds when I’m walking my dog or in the grocery store. In the gym, or for anyone who uses public transportation, the noise isolation will be great. The sound is super clear. Every high and mid tone comes through clearly and beautifully. They are a little lacking in bass, though. Rock and metal sound great on them, but EDM and hip hop are just missing that extra punch. However, considering the size and price, the bass is as good as can be expected. They’re much cleaner sounding than the much larger Ankers are. I also really like the controls. The buttons on the buds control everything that I could ask for. Volume, track selection, answer/hang up calls, play/pause, voice assistant, etc. The buttons do require a very firm press, but I figured out that I can hold the bud in place with my forefinger and press the button with my thumb and they don’t jam into my ears that way. I have not yet tested the call quality on them, so I can’t give any feedback on that. In retrospect, I probably should’ve done that before leaving this review, but I’ve already typed all of it. Hopefully the call quality is up to par with the rest of the greatness of these buds.
