Excellent Noise-Canceling Headphones
These headphones are impressive! The noise cancellation works really well, blocking out distractions. They are lightweight, comfortable, and have a sleek design. The battery lasts a long time, making them great for travel or work. The sound quality is decent for everyday use. Overall, a solid choice at an affordable price!

Strong ANC performance and LDAC included
The FirstClass 50 (FC50 hereon) is my first exposure to Back Bay Audio’s products and I’m impressed. The ANC is quite good but falls just short of the Soundcore Space 40 which itself ranks as one of my best ANC TWS and right up there with the Bose QC2 TWS. The key frequencies the FC50 struggles a little with is the upper-mids/lower-treble (which is quite common for most ANC); while testing it on the subway platform, the sound of the wheels roaring on the tracks are more pronounced vs. the two aforementioned ANC leaders. One thing I’m glad it doesn’t feature is auto-tuning of the ANC; the ANC strength stays consistent regardless of the frequencies being canceled. This is in contrast with the SoundPeats Air 4 Pro’s ANC which does a poor job at times; specifically, when riding the bus going over bumps, the clatter of the metal panels creates higher pitched noises which would occasionally cause the Air 4 Pro fits with the ANC but the FC50 handles this with aplomb.The FC50 also features a transparency mode but I find it to be rather meh. It’s perhaps good for letting in environmental sounds but I don’t find it loud enough to hold a proper conversation (YMMV), hence deducting a star for that.In terms of the sound quality, this has a darker, almost a U-shaped signature. I find the mids to be a bit recessed while the bass and treble are fine. For bass heads, there’s also a “Boosted Bass” mode that’s invoked by tapping the right bud three times but it doesn’t just boost the Bass but the Treble somewhat as well and I do feel it’s a bit strong (I’m not a basshead) so I don’t really use this mode.There are touch controls invoked via the thin shiny part of each TWS. I like that it’s not too wide as it reduces the chances of accidentally invoking the touch feature when adjusting each bud.Aside from the included cable, there are also 6 different sized tips which should accommodate all but the most extreme ear anatomies. It should go without saying by now that a perfect fit is critical to get the best ANC; it came pre-installed with the medium tips, I went one size up which improved the ANC for me. The battery life is as advertised, I got a little over 5 hrs but the case didn’t seem like it held four more charges (I’ll have to do additional testing to confirm).The overall quality is quite good but the finish is that satin-like plastic which based on experience usually becomes a sticky mess over time but that should take a few years so not an immediate concern. The other downside to this finish is that it’s a fingerprint/grease magnet.One thing I discovered in the manual and which wasn’t advertised on the product page is that the FC50 also supports the LDAC codec which should delight audiophiles (check pic). I personally don’t have a huge collection of lossless files so I won’t be using this much but it’s nice to know that it’s included (how does the saying go? “It’s better to have it and not need it than to need it and not have it”).

Worth the buy
Very clean and minimal looking earbuds. Sound is great and blocks out noise. Earbuds last long until having to charge again and you can just charge by putting into case, this will work 4 times until having to charge case. Love everything about these fit great sound great highly recommend. These were complimentary.

Great Deal
After using these headphones for a month, I have to say I really enjoy them. They have a good sound and comfortable fit, and they don’t fall out of my ears all the time like my Samsung headphones.
