The JBL Everest 110 Wireless Bluetooth headphones are actually only the second pair of wireless headphones that I have used, with my first ones being the Bose Soundsport Wireless Headphones. As such, I was eager to try the Everest 110 and compare them to the Bose as they have a slightly smaller footprint on the ear. Inside the box you will note several accessories, including a Micro USB cable to charge the headphones, three different sizes of caps for the headphones, and lastly three corresponding ear tips for the actual round headphone part. Construction wise, the headphones do feel sturdy despite the thin cable that connects them. As for the cable length, I felt like it had a good amount of slack and definitely had more room on the cable as oppose to the Bose.
On the comfort side of things, I was a bit frustrated initially with how they fit in your ear. For some reason, they kept falling out once I thought they were secured in. Ironically, it would always be the right speaker, of which I assumed because of the added weight of the volume control and microphone. After fiddling with them a bit, they eventually stayed place but on a numerous of occasions, the right speaker would eventually work its way out or just enough for the sound to change. I also tested them leaning my head towards the left and right and both would eventually work its way out. Thus, I changed the tips to the larger covers and the thicker ear tips (the default ones are medium). This was a huge improvement. Once the new tips are on, focus on pushing the ear hook piece up while slightly positioning the ear phone piece (where the JBL logo is at a slant). After a bit, the headphones did not move nor fell out when I tilted my head to each side. I recommend that you test all ear tips sizes because at first I felt like these were not going to work and was ready to write them off. Fortunately, the larger covers and its corresponding tips worked extremely well. In addition, I also tested the smaller ear tips with the largest headphone covers and that also seem to work as well (ear tips will fit all cover sizes). When I tilted my head, they did not fall out. Naturally, these will take some getting used to as the shape is a bit awkward. Nonetheless, they work and was extremely pleased after I switch the sizes.
As for sound quality, I tested various genres of music ranging from classical, metal, rap, jazz, and dance music. All the songs I tried were from my personal CD collection encoded in FLAC. They were played off my Xperia Z3+ Smartphone as well as my Z4 tablet. Any sound enhancements were disabled as well. For the most part, I generally liked how everything sounded. With the Bose as my only comparison, I was pleasantly surprised on how well these handled bass orientated tracks especially when you see how small the actual speaker really is. On extremely bass heavy songs, they did rumble quite well. For me personally, I do not like an extreme amount of bass as some might, but on the songs I observed, you can definitely tell it is there. For me, I think between these and the Bose, they are fairly close in bass, but only once the JBL's are secure in your ear. On some songs, I felt like the Bose inched out ahead, while on others the JBL seemed to have a nice clarity to its bass and surpassed the Bose. It rumbled but it did not over mask the middle or higher frequencies and I actually heard some sounds that I did not on the Bose. On more instrumental tracks, I did notice really good channel separation when the songs transitioned from the left to right speaker and vice versa. Overall, I think most people will pleased at the sound of these. Classical music sounded excellent, and I could clearly hear most of the instruments. In comparison, I think the JBL 110's handle highs and middles a bit better versus the Bose. On a side note, I wish these supported the lossless APTX codec, but sadly they do not.
In conclusion, I would say at its price these are fairly good and they do sound really good and are in some places on par or better than my Bose ones. After some frustration on initially setting them up, they do eventually become quite comfortable. They are light weight as well and once you find the sizes that fit your ears, you will almost certainly forget they are there. While I think my Bose might be a tad bit more comfortable, the JBL 110s are by no means horrible but do require some time to get used to them. Naturally, I think here the Bose design was slightly better as they happened to fit my rather large ears. Nonetheless, the JBL 110s get the job done once you fix those minor issues. Lastly, after listening to the Everest 110s for a few hours, I do quite enjoy them. As for sound quality, they really do sound amazing especially for such a small speaker. The bass was there and was not lacking as well as the higher frequencies. In addition, it did a good job of maintaining clarity throughout all the genres I tried. However, I would like to caution here that because sound quality is extremely subjective to go into these with relative reasonable expectations. For its price, I would say these do hold up really well and I do think most will be pleased aside from its initial odd shape and fitting these to your ears. Overall, recommended with some minor grievances.
