Review on 🎧 KBEAR ST1 Wired Earbuds: Deep Bass in Ear Headphones with Mic - iOS & Android Smartphones by Jose Smith

The Smabat M1 Pro are high-quality in-ear headphones with a large 14.2mm dynamic driver with composite diaphragm, detachable MMCX cables and unique, by Loudspeakers inspired Maze Bass Boost system transmission lines. .The packaging is clean, simple and neat. The plain white cardboard box with the Smabat logo contains the headphones, to which a silver-plated MMCX cable is attached. Also included are two pairs of foam ear cups, one pair of rubber ear cups, three pairs of ear hooks, and an instruction manual. All in all, this is a good presentation. The earbuds are very well made from metal and there is a dual vent on the top of the case which is the exit for the Maze camera. This sends the driver's bass output through an extended path to complement the bass response and it works very well (see text below). The included MMCX cable is made from high quality silver plated copper with a brushed aluminum 3.5mm straight plug and mating Y connector. There is also a clear plastic chin slider. The M1 Pro was used with a Hifi Walker H2 DAP via a Fiio A5 amp line-out to score and burn a wide range of music across genres for 100 hours. out. Having used the IEM for at least the past eight years, a different liner display took some getting used to. A good seal was key to getting the most out of the M1 Pro and I did it with the included foam sleeves and ear hooks. The lack of insulation was another difference, offset by the increase in volume. In fact, I found the M1 Pro to be particularly power-hungry, and the best results were achieved with an increase in amplifier volume of around 25% compared to my regular headphones. The first impression was of a very wide and deep soundstage with unusually good high-frequency imaging. Detail reproduction was excellent, especially in the high frequencies, which were very extended and crisp. The overall balance was neutral with a very linear bass profile that also showed good extension and excellent texture. The picture was also above average. The prevailing impression was "natural" with an effect similar to listening to high quality speakers. That "intimacy" found in listening to perfectly tight headphones has been replaced with an airy, relaxed and open presentation. More specifically: Bass Since Maze's bass boost is the unique offering of these headphones, I was dying to hear what the bass was like, especially since my home speakers use a transmission line bass system. Happy to report this is a success, the bass has a very natural relaxed quality with great extension. The sub-bass was deep and nicely structured, and the resolution was top-notch. The powerful bass drums on the Minnesota Orchestra's excellent 88 kHz reference recording release of Rachmaninov's Symphonic Dance No. Electronic music also benefits from this, with the deep synth bass tones of "Music from the Sky" by Charles Crevier and François Kiraly penetrating the lower regions with ease! The mid-bass continues linearly into the mids without too much emphasis, giving this range a very neutral quality and allowing all the details to be overlooked. open, transparent quality so you can hear details that other transducers can't resolve. There was no sense of a deepened midrange. The level of detail on offer here was definitely amazing, and I was able to hear things I hadn't heard before, even on familiar recordings. The guitar and percussion elements in Chris Spheeris' song "Lovers and Friends" from his album "Desires of the Heart" are played more clearly than I've ever heard, providing additional detail and creating a very lively effect that is very enjoyable was. The transient response was very sharp and made everything I played more attractive. "Music for Orchestra" by Geoffrey Bush, performed by the LPO under Vernon Handley, demonstrated this perfectly. Composed in 1967, this piece showcases all of the orchestra's instruments in a lively, contemporary composition and was enjoyed by the M1 professionals for delivering superb natural timbre and dynamic, relaxing performances. Renewal. Even at the highest frequencies, there seemed to be very little roll-off, allowing the fine detail and subtle overtones required for accurate timbre to be discerned. That was very impressive for a single dynamic driver. This resolution is typically found in devices with multiple drivers and dedicated HF BA drivers. As a result, electronic music has been particularly successful. Andrew Forrest's latest album, Freefall, consists of three long electronic tracks with an impressive array of keyboards and electronic effects. The crystalline high-frequency details in the first part revealed many details with distinctly different textures and an intricate arrangement that showed excellent separation of different elements. George Deuter's "Petite Fleur" from his album "Land of Enchantment" also impressed with the subtlety of the percussive sounds, reproduced cleanly and accurately. The orchestral strings were also well resolved with the high violin parts in the second movement of Benjamin Britten's Four Sea Interludes, Sunday Morning, beautifully rendered and presented with verve and animation. Soundstage The M1's soundstage was exceptionally wide, deep and high, much higher than any IEM I've heard and reminiscent of a full-size headphone stage. It was also like listening to quality speakers in a large room with a spacious and airy quality. The imaging and separation was also very good, with a very good arrangement of the orchestral instruments. The deep brass accompaniment at the beginning of Lyadov's "Enchanted Lake" in the recording, conducted by Charles Gerhardt, exhibited a startling sense of depth and distance: horns and harp occupied opposite sides of the frame, and in the background the drums rumbled in an ominous combination to create a beautiful live convey quality. Pink Floyd's Division Bell's "Cluster One" also made an impression, with Rick Wright's keyboards and Nick Mason's drums scattered across the stage, complemented by Dave Gilmour's moody guitar solo high in the frame to great effect. "Antarctic Echoes" from the Kurosawa soundtrack by Vangelis featured cavernous acoustics punctuated by impressive synthesizer elements that had an impressive decay that added to the track's atmosphere. I used a portable cassette player. The M1 Pro is the first earbud I've tested since IEM opened about nine years ago and I have to say it's been a revelation. The presentation differs from the IEM in that it has a more open perspective. Based on the V-shaped IEMs, initial impressions were light bass and a mid-centered sound, but further listening resulted in a nicely balanced neutral or "flat" response that allowed the music to be heard as the artist ( or manufacturer) intended. The bass was actually well extended with great texture. So it's hard to compare, but the closest sounding IEM in my collection to the M1 would be the Tin T3, which has a similarly neutral character with a bit of a bright top end. If you are looking for a converter that offers accurate and musical reproduction, then this M1 Pro should be at the top of your list.
