Monoprice Monolith M1570 Planar Magnetic Headphones: Review

Monoprice has invested a good deal of time and cash in its Monolith collection products and solutions that give a tiny bit of anything for new music listeners and residence theater fans. The variety of products features loudspeakers, subwoofers, turntables, energy amplifiers, and headphones. We a short while ago reviewed the M1070 headphones that Monoprice released to compete with some of the more economical choices from Audeze and HiFiMAN.

It’s grow to be a acquainted tale that most of the Monolith collection solutions present a whole lot of general performance for prices that are super aggressive which is not to say that they are best since just about all of them have some rather noticeable shortcomings. You just can’t be expecting perfection in precise value categories but you always do relatively well with their elements.

The superior-close headphone class is a great instance the Monoprice M1570 Planar Magnetic Open up-back again Headphones retail for $599 (even though you can locate them on sale for $449 USD) and that places them in the lion’s cage with some formidable goods like the Audeze Liquid crystal display-2, HiFiMAN Sundara, and Edition XS Headphones.

The M1570 ended up unveiled at the exact same time as the M1070 and whilst there are some similarities in between the two goods, the extra high-priced Monoprice M1570 should really be viewed as a different animal entirely.

The Skinny

Positioned on the desk, the two headphones do share a passing resemblance and use some of the similar elements in the frame and ear cups. Both equally versions also make the most of a 106mm planar magnetic driver with an impedance of 60 ohms and sensitivity score of 96 dB/mW. 

The M1570 ships in a hatbox type circumstance that is way too big to be a practical vacation companion for commuters. Monoprice incorporate two cables and two sets of earpads with the headphones.

The measurement and excess weight of the M1570 may verify to be a turn-off for some who really do not have huge heads or absence the motivation to wear a 700 gram pair of headphones for prolonged durations of time.

That somewhat shocking sum of bodyweight will make them one particular of the heaviest in the class the regular pair of ANC wi-fi headphones are among 320 and 380 grams as a place of comparison.

Most of that excess weight is in the cups and the issue for me is exacerbated by the headband style and design swapping out the Focal style single padded band with a suspension model frame would support distribute pounds improved and may possibly make these a bit far more comfortable for long listening periods.

The headband has a few other problems worth mentioning the metal is thinner than it should be and it doesn’t really feel quite stiff. This will verify to be valuable if you have to have to change the clamping drive, but it may perhaps bring about long-expression durability concerns.

The 2nd concern concerns the conclusion to put 50% of the padding on the major of the headband the place it will never ever do anything at all Monoprice demands to move most of it to the underside of the band which would enable increase the ease and comfort degree.

There are some elements of the design that are really helpful the micro-XLR ports on the ear cups have a 45° ahead angle building them a bit less complicated to wear, and the offered pads are pretty great. 

Possibly not really Dekoni good, but even now fully serviceable, comfortable, and interchangeable. The capacity to change the pads is a big additionally and the end result of consumer complaints in regard to more mature versions exactly where that wasn’t an option.

Ear pads can have a substantial impact on the audio top quality of a headphone, and Monoprice produced the correct alternative to supply two sets for people to swap out the velour pads on both the M1070 and M1570 are the better possibility due to the fact they minimize the sum of bass and far better control the reflections — resulting in a cleaner and slightly leaner sound as opposed to the inventory protein leather-based pads that ship put in on the M1570.  

The leather-based pads are 2 times as thick and present extra bass emphasis which will be preferable to some listeners — the velour pads develop a better general equilibrium which we identified preferable.

The equipped cables are similar in construction both equally are fabric wrapped with micro-XLR connectors on the headphone connector end. 1 terminates in a 6.35mm jack with a 3.5mm adapter though the other terminates in an XLR.  

Monoprice delivers a wiring diagram for the micro-XLR ports as they are not the regular wiring plan so cables for other micro-XLR headphones will not perform properly.  

Additional cables are offered for obtain from Monoprice for $55 USD every single and making a 4.4mm balanced cable ought to be a fairly straight forward by replacing the XLR jack.

The aforementioned leather pads deliver larger passive isolation and have a important impact on the bass response there is a apparent maximize in effect and definition but it experienced a slightly damaging effects on the lower midrange.

Most large open up-back again planar magnetic headphones share a linear sounding reduced end and midrange and then shed that as one particular moves into the higher midrange and treble. The M1570 do a alternatively superior career of remaining rather neutral during most of the frequency assortment with only some minor emphasis in the treble.

The small conclusion is fairly clean up sounding with enough depth and texture, and it in no way truly thickens up the rest of the tonal harmony (with the velour pads). The leather pads incorporate also significantly thickness and effects but some may perhaps like that relying on the style of tunes.

The mid bass is alternatively cleanse sounding and provides a good deal of texture and velocity there is a lot more than more than enough impression to maintain your focus the overall tonal equilibrium is on the leaner side and I suspect that bass heads will not gravitate to this facet of its general performance.

The bass overall performance is instead related to that of the Audeze Lcd-X both equally emphasize velocity and total command as opposed to influence.

Midrange efficiency is the hallmark of any planar layout and the M1570 does not disappoint the in general presentation is very linear sounding with the ideal quantity of excess weight for male vocals and bass guitar. The emphasis below is on velocity, management with quick transient reaction, and instead audible maintain and decay which offers the midrange a really all-natural sounding presentation.

Pretty much each individual style of music is effectively served by the midrange timbre, accuracy, and pacing are excellent in this range. Piano notes (which are rather challenging for some headphones to properly reproduce) are reproduced with somewhat exact timbre, fat, and decay.

Feminine vocals do element a bit a lot more emphasis than their male counterparts and that does thrust them marginally ahead of the instrumentation the upper strings also profit from this added degree of emphasis and have enough system and electricity.

The treble is extremely excellent as well but does have some minor grain to it there are a handful of little peaks and valleys in the lower and mid treble regions. This is an typically an region where by planar magnetic headphones battle and there is no query that the Monoprice M1570 exhibit some of that.

Having said that, the treble is even now extra linear sounding than a number of other types in the very same selling price array and when I like the treble overall performance of the Lcd-X and HiFiMAN Arya Stealth — both equally are almost 2 times the price of the M1570.

There is ample power and extension to make a single come to feel that the M1570’s treble is a little bit ethereal sounding and it is definitely not a fatiguing listen in any ability. Monoprice went for a protected tuning in the treble and even though it is not the last word in detail retrieval or general extension — it is the correct conclusion on their aspect.

The soundstage depth and width are great fantastic it is undoubtedly wider and there is some feeling of peak — but it is not as evident as the other proportions.

Seating the orchestra is straight ahead with no huge gaps or overlaps as instrument separation is really excellent and layering as well. Imaging is fantastic with actions simply tracked all over the phase and areas in place tightly outlined.

There was practically no feeling of compression as tunes became much more sophisticated and the motorists seemed to be capable of large dynamic swings anything that 1 should expect from substantial planar drivers.

We’re a little bit torn about these headphones.

Their sound high-quality is outstanding to other planar headphones in the exact same price assortment and it would not be an exaggeration to state that they choose aim at the Audeze Lcd-X and contend somewhat favorably. These are the most effective sounding planar headphones obtainable for $599.

Acquiring reported that, their industrial style and design leaves a lot to be sought after. The construction high quality could be better the sheet metal bends way too easily in some sections, the headband padding is in the mistaken spot, and the bodyweight is fairly substantial for a headphone in this segment in 2022.

Ad. Scroll to continue reading through.

If Monoprice can shave some excess weight off the style, transfer the padding beneath where it belongs and use a thicker gauge of metallic — they have a $500 planar magnetic headphone that can compete with everything up to $750 to $800.

An audition would make a lot of perception with these simply because of the bodyweight to see if you would be relaxed with them on your head for prolonged listening sessions.

The best information for Monoprice? They have ultimately designed a actually superb pair of headphones that are cost-effective the seem excellent is really outstanding for the rate.
