FiiO brings its latest masterpiece, meet their latest flagship tribrid IEMs, the FiiO FX17. The pair packs a whooping 13-driver per side setup featuring one 10mm lithium-magnesium alloy dynamic driver with four high-performance custom Knowles BA drivers and eight SONION EST drivers on each side. These drivers are arranged together using a precisely crafted chamber featuring both electronic and physical five-way crossover channels. Each driver performs to the best of their abilities and we are greeted with an unparalleled high-end sound experience. Using FiiO’s patented S.Turbo Acoustic design, the FX17 ensures that users are greeted with a deep, impactful bass response. The pair features premium titanium alloy ear cavities crafted to perfection. Experience the charm of true high-fidelity sonic excellence with the all-new FiiO FX17 Flagship IEMs!!

The Ultimate Driver Setup:-

FiiO FX17 is at the top of their IEM chain, and it has got this masterpiece tag because it is designed with an extensive R&D. FiiO has equipped the pair with a 13-driver configuration per side taking the benefit of dynamic driver, balanced armature drivers, and EST drivers. They feature one 10mm lithium-magnesium alloy dynamic driver unit that produces a deep and punchy bass response. It is combined with four custom-balanced armature drivers from the famous brand Knowles. Lastly, we have eight units of highly-resolving EST drivers from SONION. This 13-driver setup is tuned to deliver an impressive acoustic response that brings you every detail effortlessly.

Professionally Crafted Five-Way Crossover Design:-

FiiO is a mastermind brand when it comes to high-fidelity audio gear. The brand has extensive experience in designing premium-quality products. This experience has helped them develop this new flagship FX17. The 13-driver setup is arranged with a professionally designed five-way electronic+physical crossover design. They have implemented a 3D printed cavity for proper placement of each driver unit. With a carefully designed Electronic PCB, the electronic crossover is achieved where each driver is adjusted for the desired frequency band response. This five-way crossover not only ensures smooth sound response, but it also introduces a flat impedance curve resulting in a good source across different devices.

Patented S.Turbo Acoustic Design:-

Inspired by the turbos in supercars, FiiO has implemented this special S.Turbo technology on the FX17. This technology is a patented property of FiiO. FiiO’s professional acoustic team has designed this Turbo-like internal chamber design that cleverly enhances the bass response with more punch and a clean textured finish. At the same time, this S.Turbo technology also filters out the excessive mid-high frequency band, resulting in a cleaner sound response.

Optimized Rear Cavity For Enhanced Sound Reproduction:-

FiiO has optimized the rear cavity of FX17 for an enhanced sound response. They have dampened the rear vents to precisely control the airflow and achieve air damping balance system between the front and rear cavities of the dynamic driver. It also enhances the low-frequency depth and also results in enhanced clarity for the midrange frequencies.

Pure Titanium Construction:-

Fiio FX17 has all the characteristics of a premium flagship set. The pair features solid titanium material construction, from the inner cavity to the face covers, the entire shell is made up of high-purity Titanium material. It treats the pair with a high-strength, robust build structure. The shells are hand polished and are treated with vapor deposition that gives the pair a lustrous, premium finish.

Comfortable Snug Fit With Ergonomic Ear Shells:-

Based on user feedback and scientific research, FiiO has precisely raised the angle between the sound nozzle and the wearing surface by about 10°, this allows the IEMs to provide better comfort while wearing. They promise a comfortable and snug fit, making the FiiO FX17 a great choice for long music-listening sessions.

Top-Quality Material Premium Hybrid Cable:-

Fiio bundles the FX17 with a high-purity flagship-grade stock cable. It is a premium quality cable which is made using three different transmission material wire cores including, Gold, Silver, and Copper wire cores. The wire cores are forged at over 1000° and undergo secondary refining to form crystalline mono crystals. This cable has an interchangeable termination plug design with 2.5mm, 3.5mm, and 4.4.4 mm plugs included in the package. It adopts expanded MMCX connectors for easy and firm connection.

Fire Resistant Maybe, Not Fireproof
This small passport holder/bag from Ready Now Bags is quite unusual, it claims to be fireproof! We tested it with a lighter flame and the 'fireproof' claim initially seemed to hold up: a few seconds of direct flame on one spot had no effect on the main outside material of the bag or on the zipper material. It did cause the [nylon?] fabric running across the top of the outside pocket to start melting, and presumably the tag would also melt (as another reviewer found). My wife didn't like the bag anyway, so we decided to try a more rigorous test (initially I was hesitant, because I didn't want to ruin the bag). We put a spot in the middle of the back side of the bag in a direct candle flame for 30 seconds. It did not melt or catch fire and was only a bit degraded in appearance after the soot was scrubbed off. The inside of the bag in the area where the flame had been was hot, but not too hot to touch. We repeated the 30 second candle flame test on a corner of the bag. This time the corner of the bag caught fire after about 20 seconds (specifically, the piping material around the edge), and the fabric part of the zipper melted all the way through. I haven't tried lighting other hand bags on fire, so I'm not sure how an average one would compare, but I think 'fireproof' is too much of a claim, it may be fair to say this bag is 'fire resistant'. The material is neat and I would say attractive. Note that the bag is pretty thin [8.9in x 4.8 in x 0.7in], which is perfect for some purposes but you can't cram a lot of stuff into it. I don't know whether the RFID block works, but it doesn't seem to impede a cellphone signal at all when a cellphone is placed inside the bag (tested before fire tests). The construction quality of the bag is just okay, it's a little bit uneven/wrinkled around the edges; this material is probably difficult to work with. No functional problems, though. The pockets and slots for organizing on the inside of the bag are nice. The loop on the back that the hand strap is attached to is pretty thick and seems robust, you could attach a longer strap for shoulder or neck carry if desired. If the bag was only advertised as 'fire resistant' I would give it a higher score, but it is advertised as 'fireproof' which is quite an overclaim.

Quality and security-oriented wallet
Color: Adventure Brown - Forest Brown
This is a neatly constructed wallet. The material of the leather feels satisfying to carry unlike previous wallets. This wallet consists of many card slots, and allows ease of access between them. The wallet can fit checks, cash and is just a nice layout and style to be able to look through it. Because some of our cards support RFID and NFC technology, bad actors can try to steal our credentials. This wallet has a material to mitigate these occurrences, but like anything in security whether it be physical security controls or the wide scope of cybersecurity, do not rely on it and try to be up-to-date with the trend. I am sure we would all want to be one step above in relation to keeping our credentials secure. Still, it is an excellently built wallet and I highly recommend it.

Beautiful Wallet
Color: With NO Logo - Smooth Nappa Black
Well constructed and beautiful wallet. The black Nappa leather I ordered is soft and smooth to the touch and you can tell by the look, feel, and smell that it is high quality. I love that you can order this with both a logo and no logo for a clean look. The design on this is well thought out. I'd definitely recommend this wallet to anyone. It is an amazing value and far superior to any other $30 wallet I've ever seen.

Almost perfect!
Color: With Coin Pocket - Forest Brown
I purchased this wallet primarily for its generous number of conveniently located slots and its coin pocket. If you can't fit everything you want to EDC in this wallet, you need to think about getting a sling bag! Having returned the same model in Grizzily Brown due to a stitching defect and ordered this one in Forest Brown, I can see it is a richer, lighter shade and the finish seems smoother and more refined. Some of my cards were tight in previous wallet slots, but everything fits great in this one. Why the one star off? First, this wallet is about a quarter inch too large in all dimensions, especially thickness. While it doesn't protrude out the top of my back pocket, it is a challenge to close the button on some pants and it is also snug side-to-side, so removal involves some wiggling until pockets stretch and the wallet breaks in. The leather used in its construction is smooth but stiff at first, given that it is about twice as thick as most American or European wallet leather I've owned: think bullhide. The smell is also a little off, definitely natural cowhide but processed with whatever is used to tan leather in India rather than in the United States. Finally, this looks like something that belongs in a pair of jeans or casual pants, NOT pulled out of a suit at a Michelin star restaurant. The stitching, evenness of dye and lines are far from perfect, but what it lacks in looks it more than makes up for in every day function, character, and anticipated durability.
