Where the Sound Goes Once It Is Stuck to the Wall

The Q90 is a squat 88 mm cylinder, 53 mm deep and 180.5 g on the listing's own spec panel, with five buttons and a clock on top and a clear suction disc on the underside that the what-is-in-the-box panel shows as a separate part. Amazon pools the reviews across black and blue, but all eight are the same hardware, and the one that matters most for a shower is Clo's two-star: "one of the sound output speakers is on the back! So as soon as you put it down or suction it to the wall the sound output of the back became very muffled and it totally ruins the quality of sound!" Clo adds that, being round, "you can't really balance it on its side but if you find a way to do so then it has the potential to be a really good speaker", and face down is out because the buttons and, in Clo's words, the main bass speaker are on top.

We cannot confirm the driver layout. Bullet one claims "40mm dual bass diaphragms", which says nothing about where they point; the spec table's driver rows contradict each other; and no listing image shows anything on the underside but the suction disc. One owner in eight reports the muffling, and no other owner tells us how it sounds once it is on a wall. Dicken confirms the cup grips, "strong and holds the speaker securely", but never says where it ended up and rates the sound only against "my old speaker". Mount it on the tiles and let the 30-day window do the testing.

Dicken, who volunteers that "there are some mixed reviews about the sound with some happy and others critical", does not resolve it either. EB, a month in, puts a level on it: "The sound quality is not exceptional but very good considering the price and fact it is waterproof", and "load [sic] enough to hear clearly" for music and TV. With Jack's "can go very loud" and CW's "Sound is decent quality", five of the eight are positive on sound; Clo thinks the placement wastes it and Megan's never played.

The Pairing Sequence the Listing Never Prints

Before any of that matters you have to pair it, and the one owner who looked could not find the step in the instructions. Do this, in A. Dicken's words from a five-star: "in order to enter Bluetooth pairing mode, the speaker must first be off, then hold the on/off button. Keep holding for a few seconds after the speaker powers on and it will enter pairing mode (I could not find this information in the instructions, but it was easy to figured out and pair)." It then appears in your phone's Bluetooth list as "Q90", the only name the listing ever gives it. That is one owner's method, not the manufacturer's, so we cannot promise it works on every unit, and it is a first-run step rather than a daily fight: EB says it connects quickly when switched on after that, and CW had it running in under a minute.

The button diagram says nothing about pairing, and the only procedure PRSCFUM does publish is the four-step one for linking two Q90s together, on an A+ panel.

Megan, the one-star, names the same design: the unit would not connect to a phone, and "Button to put it into Bluetooth pairing mode is the power button which is an odd design choice." Megan returned it and bought a different model. LORD_ORiGiNALz, whose four-star is the longest of the eight, also found it tricky to pair with some devices. So: three quick, one tricky, one never connected, and the sequence came from a five-star review rather than PRSCFUM.

Water, Wet Hands and the Clock Nobody Explains

The water rating holds up across the eight. EB, after over a month of shower use, says "Very waterproof", and not one of the eight reports a water failure; LORD_ORiGiNALz adds a direct-spray test, "I've tested it in the shower, and it's worked flawlessly even with water splashing directly on it". Strictly, IPX7 is the immersion step on the IEC water-ingress scale and spray and jet resistance are separate tests, so the mark alone does not cover a speaker parked right under the head: keep it out of the main spray line if your shower allows it, and do not lose sleep if it does not.

The other reason to buy one is to leave the phone dry outside, and EB confirms you can: "Very waterproof can be controlled on the devise (only annoyance is the forward and back/up and down buttons are on the opposite site to what you would expect)". The listing's diagram labels five physical buttons, all on the top face: M for Bluetooth and FM mode, a sun icon for the lights, volume-up on the left sharing with previous track, volume-down on the right sharing with next, and power sharing with play/pause. That volume pair is the wrong way round against most kit you own, while previous and next are the normal way round on the same two buttons, so learn it with dry hands.

The clock is sold hard and never explained. Nothing on the page says how the time is set, and none of the eight mentions setting it; Dicken reports only that "once on and connected it displays the time". There is no alarm or timer control on the five-button diagram either, and the only mention of alarms in the corpus is a passing line in LORD_ORiGiNALz's four-star. Treat it as a clock you can read, not a timer you can set.

Ten Hours on the Bullets, Eight in the Spec Table

Even 6 hours, the bottom of the only owner estimate, covers a month of ten-minute showers between charges. Charging is USB-C through a side flap, with a USB-A-to-C cable in the box; press the flap fully home before it goes near the water.

Bullet four says a 1200mAh battery and "over 10 hours" of music, with the 10-hour figure repeated on the gallery spec panel and two A+ panels, while the Additional details table on the same page says 1000mAh, an average life of 8 hours and a 1.5-hour charge. PRSCFUM's listing for its sibling shower speaker reconciles them in one bullet: a 1000mAh lithium polymer battery giving "7-8h of playback time on a single charge (1.5h)", the same cell and charge time as this table, then "up to 10 hours of continuous playback at 70% volume". So the 10 hours is a 70%-volume figure on the maker's own sibling page, a qualifier that appears nowhere on this listing, and neither figure is a measurement. The one owner estimate is LORD_ORiGiNALz's "around 6-8 hours of playback time, which is decent but not exceptional"; EB had not needed to charge it after a month, which gives no hours and no usage pattern either; Jack calls the battery life good. Three of the eight.

FM Mode Is on One Button and Nowhere Else

Megan's one-star says the Q90 "has no FM radio functionality as stated in the description." Search the listing's text and radio is not there: not in the title, the five bullets or either spec table, which lists MP3 player as No, and whose one radio-adjacent row, "Antenna Location", answers with a list of compatible devices. Open the labelled button diagram in the gallery and there it is. The legend for the M button reads "Bluetooth Mode / FM Mode". That is the only surface on the listing that claims a radio, and it is a picture.

Against Megan sits LORD_ORiGiNALz, the only other owner in our eight to mention radio at all, in a four-star that reads like a template, with labelled sections and a pros list: "The built-in radio function is a nice bonus", used to listen to stations without connecting a phone. We cannot adjudicate it: Megan's unit never connected over Bluetooth either and went back, which leaves a faulty unit and an undocumented FM step both open. No tuning procedure or station readout is documented anywhere on the page.

In the UK you do not need a tuner in the speaker. BBC Sounds, Global Player and the stations' own apps stream over Bluetooth to this speaker today, whatever the M button does, and the only loss is the benefit LORD_ORiGiNALz names, which the phone itself makes moot. So do not buy the Q90 for its radio, and do not trade down for one: the FM shower speakers we looked at either rate below four stars or drop to IPX4.

Against the Pocket Speaker Most People Already Own

Most people looking at a shower speaker already own a JBL Go or Anker Soundcore pocket speaker; the Q90's case is the mount plus the readout. The bullets say the negative-pressure cup holds on tiles, glass and worktops, and once it is up the LCD shows the time and battery level, which three of the eight single out. Five of the eight, including Clo's two-star, praise the lights, and per EB and Dicken they switch off entirely. Add a built-in microphone and a spec-table range of 15 metres, which matters with the phone outside: none of the eight reports a dropout.

On build feel the two owners who describe it disagree. EB, after a month, says it "Has the feel of a robust and good quality product." Megan says "Quality felt cheap as expected for the price." Nobody has a track record: none of the eight reports a unit dying in use, but the longest ownership stated is EB's month and CW had used it once.

If that is what worries you, buy the EWA A106 Pro instead. It sits at 4.5 stars across more than 50,000 ratings, carries IP67 rather than IPX7, and its listing states a "12-month warranty and a 30-day risk free guarantee". What you give up: a carrying case and clip instead of a suction cup, so no wall-mounting; no clock, no RGB ring; and its own bullet says it dropped the microphone, the 3.5mm jack and "unnecessary buttons", so no hands-free calls. It claims 4.5 hours of play time, or up to 12 at half volume, shorter on its headline figure than either figure PRSCFUM gives. It does not fix Clo's complaint, it sidesteps it by not mounting, and it has no radio.

Why the Listing Itself Costs the Q90 Half a Point

The eight average 4.00 against the listing's lifetime 4.2 over 1,279 ratings, and they carry a slightly higher share of low scores than that full base, so we are not discounting them. We score the Q90 at 3.5 out of 5, argued from the page rather than the sample.

The case for it: five of the eight gave five stars, the cup gripped for the one owner who mentions it, and the lights are what owners most consistently enjoy. Against it stands the listing: a battery figure its own spec table contradicts, a radio claim that lives in a picture and splits the only two owners in our eight who mention it, and a pairing step written by a customer rather than the manufacturer. One buyer who never got it connected sent it back. It cannot settle the sound-when-mounted question, the one that matters most in a shower, and behind a "Limited" warranty the eight cannot say whether the Q90 lasts past a few months. That is a 3.5: half a point under the 4.0 we give most often, and a full point under the highest mark this site has awarded.

Buy it if you want a cheap wall-mounted clock-and-lights speaker for Bluetooth: stick it on the tiles the day it arrives, play something you know well, and send it back inside the 30 days if Clo was right or if the power-button hold never gets it paired. Skip it if you want radio, because nothing here can promise you one. Skip it too if you want a warranty longer than the return window, in which case the EWA above is the safer bet.
