I have been using these for almost a year now. Straight up lets do the pros & cons: Pros: 1. Batter life - its insane. With ANC on it easily lasts for 8+ hours when listening to around 60-70% volume. Plus, the case has enough juice to charge up the buds 2-3 times. 2. Soundstage - I know JBL is known for its heart thumping bass, these completely justify in that regard. However, what surprised me was the wide soundstage. I am not a hardcore audiophile but I would call myself an audio enthusiast. Instrument separation as well as vocals can be easily heard and identified over the deep bass. Yes, it requires some amount of tweaking the EQ from the default sound signature. 3. App integration/Connectivity - I used these with an android device and currently with iOS. No integration & connectivity issues whatsoever. Pairing is a charm. Though I haven't used these much for taking calls and all, with the limited time I have, I had absolutely no issues. The 4 mics seem to work like a charm. Moreover, the JBL app has been finely crafted with whatever choices you need. 4. Portability - Though the case with the sticks inside aren't featherlight (as expected with massive batteries), the sticks themselves are light enough for regular use. 5. Noise Cancellation / Talk thru etc. - I generally turn on the NC when using outdoors and its decent. Not flagship level creating vacuum in your ears, but they do cut down background noise (specially low to mid tones) quite well. The talk thru feature isn't gimmicky at all as I was skeptical of initially. Cons: 1. Multi-device connection - I wish JBL gave it a dual device connectivity since its a real pain putting the sticks in and out of the case and pair them with a different device than the one its regularly paired with. 2. Fit - This is purely personal issue I would say, I tried multiple ear-tips but somehow the left stick seems to fall off during my running sessions. Maybe I haven't tried enough changing to different tips. 3. The case locking mechanism seems to be a little flimsy compared to some of its rivals in this price range. However, I'm nitpicking here, the case and the sticks have taken quite bit of impact from my hand / pockets but held up pretty well till now. No signs of wear and tear I dare say. Overall, the JBL 230NC is a proper bang for your buck. Read more
