So after a prolonged delay (due to mail forwarding), I finally got the E50BT's yesterday. Here are my initial impressions and only based on what I'm actually able to test (e.g. I'm not going to be able to provide feedback on ShareMe since I don't have another headset with that feature) using my iPod touch 5G as source and most listening material @ 320k (only listened via passive briefly so my comments are focused on BT connection): PROS - Stylish good looks (subjective) - Nice solid construction although not on par with S400BT as that actually featured metal yokes to hold the cups whereas this is all plastic with the exception of the bolts for each hinge - One-touch instant on (this can also be a con since it can potentially be easily turned on during transport since no case is included) with quick connection to last device used - Large dial on left cup with buttons arranged in N,S,E,W pattern. Interface is pretty intuitive and easy to use once you familiarize yourself with it - Track seek by holding down Multi-Function-Button (this single button also controls pause/play and track forward/backward depending on # of presses and duration) - Volume control directly integrated with iPod's (i.e.: not necessary to adjust headphone volume independently of source - don't have Android device so can't say if it's same on those devices) - 50mm drivers offer ear-deafening volumes at max CONS - I think there should an industry-wide standard as to what can be construed as circumaural... the E50BT is of a decent size but the pad's ID measures ~46mm. I honestly don't believe I have Dumbo ears but my lobes are now pinched by the bottom of the pad and it's incurring pain after about 30 minutes worth of wearing them. Another point to this then is I wonder if this impedes the 50mm drivers thus affecting the sound profile? - Somebody in marketing/design obviously doesn't subscribe to the "less is more" school of thought; there are three very large and distinct JBL logo's; one on each side of the cup and one in silver letters on the top of the leather headband, it totally detracts from the otherwise (IMO) nice design - Somebody in engineering obviously doesn't believe or care that rattles are desired by headphone wearers as much as one desires a trephine's results to the head; seriously - who wants to hear the headphone itself? The button on the side while nicely implemented, doesn't have enough of a spring backing to prevent it from rattling. This is the exact same issue that the FSL 360 had albeit on a smaller scale. The "button" is so loose that merely turning one's head can invoke rattling... :rolleyes: - Continued use of their proprietary charging cable vs. the ubiquitous micro USB - So-so isolation (exacerbated by the fact this isn't truly circumaural - at least not for me) - Lack of memory-foam on pads - however they are reasonably comfortable - No case or even carrying pouch - if the FSL 360 can include a very nice hard shell case for the original release price of $69.99 (now only $39.99), I'd imagine that more mfg's can include one as well (especially for a headphone costing more than double) - No aptX support (confirmed via lack of indication when connected to aptX adapter) - Strange/poor bluetooth implementation - upon turn on, it'll default to pairing mode, once paired, if you pair with a new device you can't reconnect back to the first device that you paired without first deleting the profile and re-pairing. What???? :confused: - Cups can only pivot so that the pads can be folded flat towards your chest (when worn around your neck) rather than facing away from you. This prevents you from angling the cups so that it tapers towards the back of the head where it makes more sense IMO since one's ears are usually aligned closer to the back of the head. This is important to create a good seal, case in point, I wore these reversed and angled the cups to taper towards the back of my head and sure enough, this improved seal and bass as well. - While the headphones do fold, since the hinges are on the same axis, you have to twist the frame a little to make the cups overlap, they should've made the hinges offset from each other so that you can truly fold these in a compact manner with the cups resting comfortably over each other - Aesthetic triangle-shaped cut-out on the hinge bolt not fully deburred so it has sharp jagged edges (not an issue as long as you're not in habit of touching it or plan on storing in cloth case where it may snag) SOUND Being a relative newb, I'm going to keep it simple here and let those who are more articulate and experienced go into finer details. The E50BT offers a clean listening experience that isn't clinical (e.g. ATH-M50). Despite JBL touting that this features PureBass and offers "powerful bass", it's slightly bass light (IMO) and has a upper mid/lower treble hump thus while I wouldn't necessarily consider this a bright headphone, there are certain tracks that exhibit mild sibilance (e.g. Titanium (feat. Sia). Soundstage is slightly better than other closed back headphones that I have. I think it's great for Rock but not as good on other genre's (electronic). INITIAL CONCLUSION Disclosure: I'm a huge fan of Harman products but I feel they missed the boat on this one. It's a decent headphone if you love mid-centric sound profile and only ever plan on pairing it with just one device and will take advantage of the ShareMe feature but other than that I feel there are better choices in the market in this price bracket. Of course it's still early in the stages of testing and I haven't let this fully burn-in yet (albeit I remain somewhat skeptical to this phenomenon - at least in terms that my ears can hear and that my brain can remember) but even if the sound profile were to improve, some of the con's I mentioned like the weird bluetooth connection and especially that rattle will lead me on the path to returning these.

I bought one of these for my daughter and one for my niece for Christmas. After several hours the right ear stopped working already and had to take them back to the store the day after Christmas! The new one is still working though. They get great sound.

Comments about JBL Synchros White On-Ear Bluetooth Headphones:

Owned them for a day and all I can say is the sound quality is exactly what I wanted. Noise canceling, great bass, and overall great sound. They look nice, adjustable fit, and comfortable to wear. The bluetooth is easy to connect. Haven't tested the battery life too much yet, but I'm impressed.

Right side not working

Comments about JBL Synchros White On-Ear Bluetooth Headphones:

Not even a month has gone by and the left side of the headphones has already stopped working. What a shame, I was really enjoying their sound and how comfortable they are, and I would consider them to be cheap AT ALL. Therefore, a waste of money.

Comments about JBL Synchros White On-Ear Bluetooth Headphones:

Received this headset as a gift from my job for 5 years service. Am enjoying the Bluetooth capability. Fit on the ears is a tad tight, but a minor pt. I haven't seen how to register them for warranty coverage? What's the best way? Teedmk

I love these headphones

By 

from Tempe, AZ, United States

Comments about JBL Synchros White On-Ear Bluetooth Headphones:

After a lot of research, I settled on the Synchros E50BT, and honestly I couldn't be happier. The sound quality is amazing, and I just started using them yesterday! Great distance on the Bluetooth reception, I can walk across my office without having to carry my phone with me, and the battery life has been great thus far. Have used them 8 hours now and I'm still showing full battery. My one complaint is the ear cups themselves, as they don't completely cover my ears, but they do create a pretty solid seal and I don't get any noise from around me in the office with them on. I love the ability to run passive as well, as I will be traveling over the holidays and know I can't have Bluetooth on during the flight. Overall, I am very pleased with these, and they have again proven that JBL should always be my choice when selecting quality speakers/headphones. Love you guys! Thank you!
